INTRODUCTION  
1. INTRODUCTION  
Preamble  
Thank you for choosing the DYNACORD PROANNOUNCE System. With the PROANNOUNCE System you  
purchased a high-quality product which is going to satisfy your highest demands. This extraordinarily flexible and  
versatile system allows the configuration of either small or complex installations as well. Most functions are realized  
through software modules, which - when compared to conventional PA-systems – not only reduces the amount of  
cabling but also the costs. Next to extensive audio signal generating and distribution functions, the PROANNOUNCE  
system provides ample control functions. On one hand, these functions offer the possibility to register and rate  
external events, as well as to control different external components, on the other hand. Boolean operations and  
relations to the internal state of the system can be programmed as well.  
To be able to take advantage of all possibilities that are offered by the PROANNOUNCE system, we would like to ask  
you to read this handbook carefully. For getting a quick overview about the PROANNOUNCE system's components  
and functions, we recommend consulting the chapter System Description.

OPERATION INSTRUCTIONS  
CAUTION !  
1.  
2.  
To prevent the risk of fire and shock hazard, do not expose any appliance or module high humidity or water.  
Make sure that no alien objects enter the appliances or get in contact with the modules – especially no metal parts  
– since this would very likely cause dangerous electric shock and/or malfunctioning. There are no user-  
serviceable parts located inside the appliances or on the modules. Opening appliance enclosures and/or rack  
shelf systems can lead to dangerous shock hazard. Do not open or try to reach inside the enclosures of  
appliances. Leave installation, servicing, maintenance, and any other works on the appliances or the rack shelf  
system to qualified service personnel only.  
3.  
4.  
When exposing appliances/modules to extreme temperature changes, i. e. when moving them from the outside  
into a warm room, condensation may occur. If so, it is necessary to wait before use until the devices gained room  
temperature.  
Under no circumstance place any liquid-containing cans, glasses, mugs, etc. on top of an enclosure. In case any  
liquids or foreign obstacles entered the enclosure of an appliance, immediately unplug the device from the mains  
supply and have it serviced.  
5.  
6.  
7.  
8.  
Make sure that appliances/modules are always provided with sufficient ventilation. Do not expose devices to  
direct sunlight or any other heat-radiating source.  
Do not expose appliances/modules to extreme dust or humidity. Operating the system under environmental  
conditions like these can lead to severe damage through fire or cause bodily harm to the operator.  
Make sure that the stated mains voltage is in accordance to the specifications of your mains supplier.  
Mismatching will cause severe damage to all appliances/modules.  
Make sure that mains cords and/or any other cabling are not damaged or being jammed by the turning frame or  
any other movable parts of the rack shelf. Damaged cables can lead to fire hazard and/or can be the cause for  
electric shock.  
9.  
The mains cord of the rack shelf installation is supplied with a 3-pole plug to minimize the risk of electric shock. It  
should only be connected to a grounded wall outlet. Under no circumstances insulate the ground contact. When  
using an extension cord, always use a 3-pole grounded cable. When using multi-outlets for distributing, make sure  
that the wall outlet's capacity is not exceeded, since this could lead to fire hazard and/or can be the cause for  
electric shock.  
10. The DPM 4000 contains a lithium-type battery to provide the internal clock with power. The lifetime of this battery-  
type spans approximately 10 years. When the battery's voltage drops below a certain minimum, an according  
message appears on the paging station display. In this case, the battery has to be exchanged by an EVI Audio  
GmbH authorized service technician. Under no circumstances try to exchange the battery yourself!  
CAUTION! There is a severe risk of explosion when incorrectly exchanging the battery. Only replace with  
the same type of battery or one especially recommended by the manufacturer. For  
environmental awareness: Take care of used batteries following the manufacturer's advice.  
11. Obeying the VDE-regulation DIN VDE 0800 is necessary when installing and operating 100V-loudspeaker  
systems. Especially with 100V-loudspeaker systems that are part of an emergency alert installation, protection  
measures have to be in accordance with safety class 3 regulations.  
CAUTION! During operation, speaker group connectors (POWER OUTPUT) may carry shock hazard output  
voltages (>34V peak value). Thus, the installation of the connected loudspeaker groups has to in  
accordance to security standards and regulations as stated above.  
12. Make sure to establish all connections before operating the system. Connecting/disconnecting cables during  
operation can cause malfunctioning or damage to the correspondent appliances.

SYSTEM DESCRIPTION  
3. System Description  
This chapter provides an overview of the general configuration of the PROANNOUNCE system and its most important  
functions. The following block diagram shows a typical PROANNOUNCE system installation including the DPM 4000  
central unit, paging stations, audio equipment, amplifiers, power supply unit, relay board assemblies, loudspeaker lines,  
and control board assemblies for external signals.  
figure 3.1 PROANNOUNCE System  
3.1  
General Overview  
The digital PROANNOUNCE manager DPM 4000 represents the central unit of the system. It is used to control and  
monitor all connected components via several serial interfaces. The chapter Single Device Descriptions contains all  
necessary information about the DPM 4000 and its available modules.  
The kind and amount of connected audio sound sources, amplifiers, and relay board assemblies are extremely  
variable. This allows configuring the system to basically match any requirement. The system is capable of managing up  
to 16 paging stations and up to 100 output lines. More than 150 control inputs and outputs are available for controlling  
and monitoring purposes providing the possibility to generate and manage logic levels and analog levels as well. For  
detailed information, please refer to the chapter DCS 400 Control System.  
Configuration and documentation of a PROANNOUNCE system installation is established through the use of the  
PROANNOUNCE Designer software – a comfortable graphical user interface that runs on a PC under Windows  
95/98/NT. This allows changing the system’s setup at any time to meet new requirements, without the need to alter the  
actual installation. The PC has to be connected to the system only when loading or changing its configuration. During

SYSTEM DESCRIPTION  
normal operation, PC-interaction is not necessary. Anyway, in most cases the permanent connection of a computer  
bears benefits, like displaying detailed status reports or the printing of protocols. It also offers the possibility for remote  
diagnosis and remote maintenance via modem.  
3.2  
Audio Routing  
The DPM 4000 employs a digital audio matrix providing 4 inputs and 4 outputs. Additional matrix junctions for the  
integrated gong and alarm signal generators, the vocal recording/playback unit, and the lock-on of the pilot tone and its  
evaluation are incorporated. All input signals and internally generated signals can be freely mixed inside the matrix and  
outputted through the 4 amplifier channels. Routing speaker lines to these amplifier channels is achieved via the relay-  
matrix, which offers up to four separate audio buses simultaneously, while the DPM 4000 takes over the management  
of all these signals according to their priority.  
Next to connecting paging stations, the audio inputs also serve for the connection of other audio sound sources, like  
microphones, mixers, CD-players, cassette decks and DAT-recorders, tuners, etc. Several different input modules are  
available to optimally adjust and match signal levels and connections.  
3.3  
Volume And Tone Controls / Delays  
The PROANNOUNCE system provides individual volume controls for each input, output, and paging station. Even the  
internal audio sources, like gong/alarm tone generators, voice message playback, and pilot tone generator employ  
individual level controls, each. Additionally, it is possible to set an attenuation that unanimously affects the inputs. This  
value determines the degree, by which the input signal is attenuated during the reproduction of messages or other  
signals with a higher priority setting. This allows to smoothly fade-out and fade-in background music during the  
transmission of important messages.  
Besides, each of the four inputs embodies three fully parametric digital filters allowing for optimal tone control. The  
filters provide different filter types like Hi-/Lo pass filters, shelving filters, and peak-dip-filters providing the possibility for  
adjusting the sound within the entire audio transmission range. Factory-preset filter settings for the DPC 4000 Series  
paging stations are already provided.  
Setting volume levels and filter parameters is accomplished via PC during the configuration procedure. Further, it is  
possible to alter any volume setting during the later operation of the system via special-function keys on the paging  
stations or through external controls that are connected to analog or digital control inputs.  
All four outputs employ digital delays allowing signal delays of up to 330 ms per channel. Natural delays, resulting from  
loudspeaker positioning which causes time differences in the traveling of sonic events or environmental circumstances  
related to architectural characteristics of the location, can be equalized without additional effort.  
3.4  
Signal Generators / Voice Message Memory  
The DPM 4000 provides a variety of tone generators for the generation of gong, alarm, and text signals. Signal  
generation is realized through DSP-algorithms, which are extremely flexible in use, so that they can be adjusted to  
match nearly any possible application. Factory presets include 6 different gong signals, 18 different alarm signals, plus  
sine cycle at any frequency. Other than in comparable equipment, the PROANNOUNCE signal generating DSP-  
algorithms do not take up any extra storage of the voice message memory.  
In addition, a voice message recording/playback module providing CD-quality sound is optionally available. With a total  
recording time of approximately 6 minutes, 25 different messages are being managed. The DPM 4000 provides the  
possibility to install up to four optional FLASH-memory modules, depending on individual desires or requirements.

SYSTEM DESCRIPTION  
3.5  
Paging Stations  
The DPC 4000 Series paging consoles are mainly meant for transmitting voice messages and calls but also to  
manually control the PROANNOUNCE system. Available paging station functions are: line/group selection, voice  
messages, program assignment, launching gong and alarm signals, and reproduction of voice message memory  
announcements. Additionally, special commands include volume control, monitor selection, preset switching, lighting  
control, function status indication, etc. Thus, it is possible to configure the paging consoles to serve as operation panels  
for general control purposes.  
If a voice call is being launched into a speaker line that is already busy with other audio transmissions, the caller gets a  
busy-sign, i. e. the BUSY-LED blinks. In case the calling terminal has a higher priority it will interrupt any messages  
from other paging stations or audio signals with lower priority levels. Interruption does not take place uncontrolled  
anymore. Before actually interrupting a transmission, the blinking LED indicates that a line or group is busy when  
selecting a destination, leaving the choice to the operator, whether he/she immediately wants to interrupt or wait upon  
the conclusion of the momentary reproduced program.  
3.6  
Control Inputs And Outputs  
By using the control inputs, it is possible to link the PROANNOUNCE system to fire alert systems, burglary alert  
systems, or to a central operating desk. It is also possible to connect external switches, breakers, rotary controls or  
rotary encoders, respectively to query control outputs of external units (power supplies, power amplifiers, …).  
The control outputs allow switching external devices ON or OFF, trigger signals and events, switch monitor sources,  
remote control doors, gates or shutters, generate analog signals for the control of multimedia systems, etc.  
A total of 130 control inputs for logic levels, 128 control inputs for analog levels, 16 inputs for rotary encoders, 127  
logic-control outputs, and 128 analog-control outputs are usable.  
3.7  
Clock / Calendar  
The PROANNOUNCE manager DPM 4000 has an integrated quartz-controlled real-time clock which can be set for  
radio-controlled DCF 77 operation using the optional antenna (DCF 77 tuner NRS 90193). The system clock  
automatically recognizes leap years and, if in DCF 77 mode, automatically switches between daylight saving time and  
standard time.  
The system clock provides the possibility to control up to 40 external slave clocks. For this purpose, the DPM 4000  
employs a special, short-circuit-proof output for pole changing impulses. Slave clocks are automatically re-  
synchronized whenever a time difference to the system clock is detected; like for instance in cases of power outage or  
when time values were entered manually.  
It is possible to activate pre-set functions like break-gong signals, background music, remotely controlled gates, switch  
lights ON/OFF, etc. when using system clock and calendar function together All the functions mentioned before can be  
programmed for specific days; but also hourly, daily, weekly, monthly, and yearly activation is possible. Up to 500 time-  
controlled events can be programmed.  
3.8  
Monitoring  
The PROANNOUNCE manager DPM 4000 embodies a monitor amplifier with headphones/speaker output. The  
integrated logic-switching circuit provides the opportunity to listen to the signals of any internal input and output.  
Assigning external sound sources to the monitor bus is possible as well. This additionally allows monitoring amplifier  
outputs or pre-listen to the contents of external voice message memories and other audio devices.  
The remote control’s wiring already includes all the cabling necessary for the pre-/post-listen feature when using  
remote-controlled amplifiers.  
When using the DCS 420 PROANNOUNCE MONITOR MANAGER, easy programming and operating is available. See  
also chapter 5.4.7

SYSTEM DESCRIPTION  
3.9  
Macros  
Macro is defined as the combination of several commands, functions, and their parameters in an internal consecutive  
sequence. For example a gong signal with specific volume and priority settings has to be transmitted in different calling  
zones, while simultaneously activating a control output. In that case the macro consists of the functions “gong” and  
"control" with the parameters gong-type, volume setting, priority number, calling zone numbers, and the type and id-  
number of the control output.  
It is possible to initiate a macro via the special function keys on the paging consoles or to trigger it via control input. It is  
also possible to combine a macro with the internal clock or calendar.  
The PROANNOUNCE system provides a number of pre-programmed macros, where only individual parameters still  
have to be entered. Additionally, it is possible to combine several macros in a sequence. Using pre-defined macros and  
sequences lets you create new, user-specified and application-related macros, which basically are capable of  
managing any control function imaginable. A total of up to 250 user-macros can be programmed.  
3.10 Interfaces  
Besides its control inputs and control outputs, the PROANNOUNCE system provides additional interface ports. The  
connection of paging consoles to the PROANNOUNCE manager DPM 4000 is performed via serial RS-485 ports. This  
allows connecting up to four terminals at a single port. Power amplifiers and the DCS 400 controller are connected to  
another independent RS-485 port, which allows direct management of up to 64 power amplifiers and 8 DCS 401.  
Connecting a PC is established via serial RS-232 port on the rear panel of the DPM 4000. It is not necessary for the  
PC to be permanently connected to the DPM 4000.  
An additional RS 485-interface offers the possibility to operate several DPM 4000 in a network.  
3.11 Safety Standards  
The PROANNOUNCE system complies with all applicable requirements of the IEC 849 standard – electro acoustics  
emergency alert PA-systems. The digital PROANNOUNCE manager DPM 4000 guards and monitors its entire internal  
functions. All connected paging stations and power amplifiers, including the wiring, are monitored via polling and pilot  
tone functions. Using the remote control units in the power amplifiers, it is also possible to monitor the loudspeaker  
lines. Of course, the PROANNOUNCE system is also prepared for operation with emergency power supply. In case of  
a power outage, the DPM 4000 takes over the entire power management; i. e. all internal and external power  
consuming components are switched to stand-by mode. Only when necessary, they are turned on again. This  
minimizes the total power consumption efficiently and guarantees maximum operational reliability when the system is  
operated from a battery power source.  
Fault messages are being displayed in plain text on the paging console displays and a floating contact is provided for  
collective fault messages. An automatic protocol facility of the system's individual state of operation is optionally  
possible. This protocol is stored in the DPM 4000's internal memory. If necessary, it can be displayed on the screen of  
a connected computer or printed out via a printer.

5.1.2 Front View  
figure 5.2 DPM 4000 front view  
The following controls and indicators are located on the DPM 4000's front panel:  
1. LED DCF 77  
This LED indicates the operation mode of the DCF 77 radio-controlled-signal receiver. The following table shows  
the different indications and explains their corresponding status:  
LED indication  
OFF  
status  
No radio control signal detected or no DCF 77 antenna connected. The  
system clock is quartz-synchronized.  
ON  
The radio control signal is received. The system clock is synchronized  
to the DCF 77 signal.  
Blinking, one cycle per  
second  
The radio control signal is present and the system clock is being  
synchronized. This procedure can take up to 2 minutes. After  
synchronization is complete, the DCF 77 LED light continuously.  
Blinking, fast  
The radio control signal is detected but its reception is jammed. Re-  
adjusting the DCF 77 antenna or choosing a location with improved  
reception is recommended.  
2. LED READY  
This LED indicates the operation mode of the PROANNOUNCE System. After switching the power on, the READY  
LED blinks while the system boots. Depending on the complexity of the installation blinking can take several  
seconds. After successful initialization, the LED lights, signaling that the system is ready for operation. Whenever  
erroneous operation – either in the DPM 4000 or in one of the connected components – is detected, the LED goes  
out indicating that a system error occurred. When the system power is OFF, the READY LED is OFF as well.  
3. LED POWER  
This LED lights as soon as a power source (24 V =, power supply or battery) is connected to the DPM 4000. The  
LED does not light when the DPM 4000's power supply is disconnected, switched off or fails.  
4. LED FAULT  
This LED lights during a reset or when an internal watchdog error is being detected within the DPM 4000. It also  
indicates erroneous operation of external system components (power amplifiers, paging stations, relay boards, ...).  
The LED is connected to the READY relay on the rear of the appliance, which allows remote indication of system  
errors.

figure 5.3 DPM 4000 rear view  
The following module ports and connections are located on the rear panel of the DPM 4000:  
1. DC INPUT 24V ==  
The DPM 4000's power supply source has to be connected here; a 24 VDC power supply or a PROANNOUNCE  
system battery module using insulated AMP flat-connector plugs 6.3 x 0.8 mm. The DPM 4000 is protected against  
polarization mismatch and all positive and negative conductors within the device are fuse-protected. The fuses are  
located inside the enclosure on the printed board assembly 80430. The connection cables have to be 1,5 mm2 in  
diameter at least. With this diameter the cable length of a single path should not exceed 4.0 m (max. drop in voltage  
<1V).  
CAUTION: Using the DPM 4000 is only permissible with batteries that are not grounded or provide a grounded  
negative pole. Operation with grounded positive pole is not admissible.

5.1.5 2-Channel Paging Station Module (NRS 90215)  
This 2-channel audio input module is meant for the  
connection of DPC 4000 Series paging consoles. Each of  
the two input channels provide RJ-45 sockets allowing  
the connection of up to 4 paging stations plus paging  
station extensions per input. The microphone terminals  
are interconnected via 6-conductor parallel cables. The  
module can be installed in slot 1 and slot 2.  
DPM - PCI  
DPC 4000 IN  
A
Next to the electronically balanced audio input, each input  
connector provides a serial RS-485 interface port and the  
power supply connection for the paging stations (see  
also: pin-assignment of the RJ-45 connector). The paging  
stations' power supply employs an electronic,  
programmable fuse, through which the maximum output  
current can be matched to meet actual system  
accommodations. This prevents the entire installation  
from malfunction, in case of short-circuit occurring in a  
single paging station only.  
DPC 4000 IN  
B
Input channels can be switched separately onto the  
monitor bus and you can monitor the audio signal via  
headphones or loudspeaker, either which is connected to  
the monitor output. Automatic pilot tone surveillance of  
the entire input stage is integrated as well. If necessary,  
retrofitting the audio inputs with transformers is possible.

figure 5.7 2-channel paging station module  
Note:  
When connecting several paging consoles to a single input, please keep in mind that line interruption or  
short-circuit can cause malfunction of several or even all paging stations of that specific line. In  
emergency alert installation, connecting security-related consoles to individual inputs is therefore of  
major importance.

DEVICE DESCRIPTIONS  
Pin-Assignment Of DPC 4000 Connectors And The Extension Cord:  
Connecting DPC 4000 paging stations to the DPC 4000 IN connector is established through the use of common RJ-45  
extension cords, where the conductors are twisted in pairs as follows: pair 1 = 1/2 (24 V/GND), pair 2 = 3/6 (free), pair  
3 = 4/5 (RS-485), pair 4 = 7/8 (AUDIO).

Retrofitting Input Transformers:  
In case galvanic separation of the audio signal is necessary, the module is prepared for retrofitting two input  
transformers. Separate NRS 90208 extensions consisting of audio transformer and insulation plate each are needed  
per input channel.  
When retrofitting the transformers, please proceed as follows:  
1. Disconnect the DPM 4000 from the mains power supply.  
2. Loosen the two locking screws and carefully slide the module out of the slot.  
3. Remove the two resistors of the corresponding input channel (IN A: R6 / R7, IN B: R3 / R8).  
4. Place the insulation plate between the transformer and the printed board assembly and solder the transformer to  
position T1 for IN A or to position T2 for IN B.  
5. Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.  
6. Fix the module in place using the two locking screws and reconnect the power supply.

Retrofitting Input Transformers:  
In case galvanic separation of the audio signal is necessary, an input transformer can be retrofitted to channel B  
of the MIC / LINE module. This is accomplished using the extension kit NRS 90233.  
When retrofitting input transformers, please proceed as follows:  
1. Disconnect the DPM 4000 from the mains power supply.  
2. Loosen the two locking screws and carefully slide the module out of the slot.  
3. Remove the two resistors of input channel B (R7 / R11).  
4. Solder the transformer in position T1 onto the printed board assembly.  
5. Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.  
6. Fix the module in place using the two locking screws and reconnect the power supply.

5.1.9 MIC/LINE + Paging Station Module (NRS 90234)  
This 2-channel audio input module is meant for the  
connection of DPC 4000 Series paging stations and other  
external audio sources. The RJ-45 socket of channel A  
allows the connection of up to 4 microphone terminals  
plus paging station extensions. The MIC / LINE input of  
channel B is furnished through an XLRF-type connector  
allowing the connection of microphones, mixers and other  
audio signal sources. The module can be installed into  
slot 1 and slot 2.  
Next to the electronically balanced audio input, the DPC  
4000 input connector provides a serial RS-485 interface  
and the power supply for the connected paging consoles  
(see also pin-assignment of the RJ-45 connector). The  
paging stations' power supply employs an electronic,  
programmable fuse, through which the maximum output  
current can be matched to meet actual system  
accommodations.  
The MIC / LINE input employs an internal switch (PAD)  
providing 30 dB of attenuation. The GAIN-control located  
on the appliance's rear panel offers additional control in a  
range of 40 dB. The input is electronically balanced and  
prepared for retrofitting a transformer. Phantom power  
can be switched via jumper. If necessary, a compressor /  
figure 5.22 MIC/LINE + paging station module (NRS 90234)  
limiter circuit can be incorporated in the audio path.  
Input channels can be switched separately to the monitor  
bus and you can listen to the signal via headphones or  
loudspeaker, either which being connected to the monitor  
output. Automatic pilot tone surveillance of the entire  
input stage is integrated as well.  
Note:  
When connecting several paging consoles to a single input, please keep in mind that line  
interruption or short-circuit can cause malfunction of several or even all paging stations of that  
specific line. In emergency alert installation, connecting security-related consoles to individual  
inputs is therefore of major importance.

Pin-Assignment Of RJ-45 Socket And Extension Cord:  
Connecting DPC 4000 paging stations to the DPC 4000 IN connector is performed using common RJ-45  
extension cords, where the conductors are twisted in pairs as follows: pair 1 = 1/2 (24 V/GND), pair 2 = 3/6 (free),  
pair 3 = 4/5 (RS-485), pair 4 = 7/8 (AUDIO).

Internal Settings:  
1. MIC / LINE switching and sensitivity of the MIC / LINE input  
The MIC / LINE input's internal PAD-switch (S1) allows switching the channels' sensitivity between  
microphone and line levels (30 dB). The GAIN-control on the module's front panel is provided to precisely  
adjust the input sensitivity (range 40 dB).  
In addition, a MIC/LINE jumper (JP1, pins 5-6) is located on the printed board assembly, which allows  
correctly configuring the input. It is important to change the jumper accordingly (open = LINE, closed = MIC)  
when changing the MIC/LINE switch.  
When shipped the switch S1 is pre-set to LINE and the jumper JP1 to its open position.

2. Phantom power  
Closing the pins 1-2 and 3-4 of the jumper JP1 offers the possibility to engage 24 V phantom power for  
microphones that are connected directly. When shipped, the jumper is factory pre-set to its “open” position (no  
phantom power).  
3. Compressor / Limiter  
The MIC / LINE input channel embodies a compressor / limiter circuit which can be incorporated into the  
signal path via jumper JP2 (position COMP). Normally, the compressor / limiter should be used to eliminate  
the risks of overdrive and clipping, when directly connecting a microphone. When shipped, the jumper is pre-  
set to its “Linear” position (LIN).

Retrofitting Input Transformers:  
Retrofitting two input transformers onto the module is possible for the case that galvanic separation of the audio  
signals is needed. For the DPC 4000 input a NRS 90208 extension is needed, which consists of an audio  
transformer and an insulation plate. For the MIC/LINE input a NRS 90233 extension is needed.  
When retrofitting input transformers, please proceed as follows:  
1. Disconnect the DPM 4000 from the mains power supply.  
2. Loosen the two locking screws and carefully slide the module out of its slot.  
3. Remove the two resistors of the corresponding input channel (IN A: R8 / R9, IN B: R3 / R4).  
4. With the DPC 4000 input (IN A), you have to place the insulation plate between the transformer and the  
printed board assembly. Then solder the transformer in position T2; with the MIC/LINE input (IN B), you have  
to solder the transformer in position T1.  
5. Re-insert the module into the slot and carefully push it into the DPM 4000 until it firmly locks in place.  
6. Fix the module in place using the two locking screws and reconnect the power supply.

5.1.10 2-Channel LINE Output Module (NRS 90218)  
The output module is meant for the connection of power  
amplifiers with an input sensitivity of 0 dB or +6 dB. Two  
XLRM-type connectors allow the connection of up to 20  
power amplifiers each. The audio signal is electronically  
balanced; if necessary, transformers can be retrofitted.  
The module can be installed in slot 3 or slot 4.  
DPM - OUT  
The output channels can be switched separately to the  
monitor bus and you can listen to the signal via  
headphones or loudspeaker, either which is connected to  
the monitor output. Automatic pilot tone surveillance of  
the two output channels is also integrated. The jumpers  
for adjusting the output voltage to 0 dB or +6 dB are  
located on the printed board assembly. At the same time  
you have to alter the jumper setting of the monitor signal  
correspondingly.

5.1.11 8 I/O Control Module (NRS 90219)  
This control module provides 8 floating control inputs and  
7 floating logic level outputs (0 V, 24 V). An additional  
output provides pole change impulses for controlling  
slave system clocks. Contact is established via 4 x RJ-45  
sockets providing 8 contacts each. The module can be  
installed in slot 5.  
The slave clock output (NU, OUT 1) is short-circuit proof;  
up to approximately 40 slave clocks can be connected.  
Please make sure to connect all slave clocks according to  
their correct polarity.  
The control outputs (OUT 2 - 8) are capable of switching  
voltages of either polarity and up to a maximum current of  
1 A.  
The control inputs (IN 1 - 8) are capable of handling  
voltages of either polarity between -31 V and +31 V; for  
voltages between 0 and 5 V the inputs are not active  
(low), for voltages between 10 V and 31 V the inputs are  
active (high). The control inputs can ignite switching  
functions or macros either during a change of state or in  
any stationary state. This offers the possibility to monitor  
line idling currents (e. g. in fire alert system installations).  
figure 5.31 8 I/O control module  
Note:  
The opto-coupler inputs are primarily meant to prevent noise loops that can result from dropping  
voltages in long distance cabling. They are not suitable for separating networks from each other.  
Therefore, only floating sources should be connected.

PROANNOUNCE – DPC 4000 Paging Consoles  
5.2.1 System Overview  
The PROANNOUNCE system includes 5 different models of DPC 4000 Series paging stations and one paging  
station extension. All microphone terminals employ gooseneck microphones, 6 or 8 function keys and a covered  
alarm key. An additional alarm key and a key-locked switch can be retrofitted. The paging stations are available  
with 10, 20, 30, or 50 selection keys. All models also employ LC-displays (2 lines with 16 characters each).  
The following list provides you with an overview of available paging station models:

All paging consoles are processor-controlled and extensive monitoring functions are provided. The watchdog  
function monitors the processor system while a switchable pilot tone generator monitors the audio section.  
Additionally, the internal supply voltage is constantly measured. When it falls below a critical threshold an alert  
message is being displayed. The line surveillance function recognizes any line-interruption and/or short-circuits in  
the audio and RS-485 control cabling. Upon the detection of failure a corresponding message is displayed.  
The PROANNOUNCE Designer software allows comfortably configuring the paging stations. Its graphic,  
dialogue-oriented user interface offers effortless assign of key functions, priorities, options, and many other  
paging station functions.  
Note:  
Up to four paging consoles can be connected to a single input of the central unit. However, it  
is important to keep the fact in mind that in case of line interruption and short-circuit several  
microphone terminals may fail. Despite, one input allows only launching one message at a  
time. All other connected paging stations are presented with a busy-message. If these  
restrictions are not acceptable, every microphone terminal – or at least all directing stations  
and other important paging stations – should have its own input at the central unit.

Selection Keys and LED’s  
Depending on the individual paging station model, 10, 20, 30, or 50 selection keys with corresponding LED’s  
are provided. The selection keys are used to pre-select areas or groups for the reproduction of messages,  
gong or alarm signals, vocal messages, or to assign programs (pressed once = ON, subsequently pressed =  
OFF). The LED’s indicate the momentary selection status (also refer to the paragraph “indications”). It is also  
possible to assign special functions or no function at all (no function assigned) to the selection keys. Assigning  
functions is performed during the configuration procedure via PC.  
Note:  
When shipped, these keys are factory pre-set as area selection keys, where key 1 –  
area 1, key 2 – area 2, ..., key n – area n.  
2

4
ALL key and LED  
The ALL key allows the selection of all programmed areas at once for transmitting messages, gong or alarm  
signals, vocal messages, or to assign programs. One time pressing selects all areas. The corresponding  
LED’s and the ALL LED are lit. Subsequent pressing cancels the selection.  
CANCEL key  
This key offers different functions, depending on the actually selected operation mode, e.g. cancel calling  
pattern or cancel program-assignment. Which function is carried out at times is explained in detail in the  
paragraph OPERATION.  
GONG key (ESC) and LED  
Pressing this key starts the transmission of a gong signal in the pre-selected areas or groups. The GONG LED  
lights or blinks during the transmission of a gong signal. What kind of gong signal is being transmitted is  
defined during the configuration procedure. Pressing the STOP key cancels the reproduction of the gong  
signal.  
While in setup-mode, this key is used to return to ‘normal’ user mode (ESCAPE = leaving setup-mode).

TEXT key () and LED  
Pressing the TEXT key starts a prerecorded message (optional voice reproduction), which is transmitted into  
pre-selected areas or groups. The TEXT LED lights or blinks during the transmission of a prerecorded  
message. The desired text message is selected during the configuration procedure. Pressing the STOP key  
cancels the reproduction of a text message.  
While in setup-mode, pressing the TEXT key decreases the selected parameter value (parameter entry).  
6
7
TALK key and BUSY-LED  
This key activates a message for pre-selected areas or groups. The BUSY LED lights during transmission.  
The TALK key has to be pressed until the end of a message. The BUSY LED blinks when one or several  
areas are busy or when an event with higher priority setting interrupts the output message (see paragraph  
indications). In the latter, it is necessary to repeat the message.  
ON key (<) and LED  
This key turns the system’s power on or off. Turning the power on can take several seconds. The ON LED  
blinks while the system boots. The ON LED lights steadily when the system is operational. To prevent  
inadvertent erroneous operation pressing the key for at least 1 second is necessary when turning the power  
off. It is also possible to prohibit the operation of the ON key during the configuration procedure.  
In setup-mode this key is used to select the previous parameter (parameter selection).  
8
STOP key ()  
Pressing the STOP key cancels an output alarm signal or text message. Terminating an alarm signal is also  
possible by subsequently pressing the ALARM key. Only events that were triggered from a specific paging  
console can be stopped from the exact terminal with the exception of the directing station. This terminal allows  
canceling all signals.  
While in setup-mode, this key increases the selected parameter value (parameter entry).  
9
PROGRAM key (>) and LED  
Pressing the PROGRAM key selects the program assign mode. The selection keys are used in this mode to  
assign a program (background music) to the desired areas or groups. The PROGRAM LED lights while being  
in the program assign mode. In this case the selection LED’s indicate the areas / groups the program is being  
transmitted into.  
Keeping this key pressed and simultaneously pressing the STOP key selects the setup-mode and the  
PROGRAM LED starts blinking. Now you can alter preferences or make other changes as described in the  
chapter 5.2.7 Paging Station Configuration In Setup Mode.  
When in setup-mode, this key is used to select the following parameter (parameter selection).  
10 ALARM key and Indicator  
Pressing the ALARM key starts an alarm signal that is transmitted into all areas. The alarm indicator lights  
when launching an alarm. Pressing the STOP key or subsequently pressing the ALARM key terminates the  
alarm signal. What kind of alarm signal is being transmitted is defined during the configuration procedure of  
the PROANNOUNCE system.  
11 Optional Key-Slots  
These slots allow retrofitting an additional covered key and a key-locked switch. The front panel is already  
prepared for the installation of two 18 mm pushbuttons / switches. You only have to cut suitable holes into the  
front panel foil. Internal fittings and cables are also already prepared. The newly installed switches’ functions  
are assigned during the configuration procedure via PC; e.g.: second alarm-pushbutton for transmitting an  
alarm signal into specific areas (selective alarm), or assigning the system ON / OFF function to the key-locked  
switch.  
Detailed information and installation instructions are provided in the chapter 5.2.13 Optionally Available  
Accessories.

12 Microphone  
After pressing the TALK button and after the BUSY LED lights making announcements in pre-selected areas  
or groups is possible using the integrated gooseneck microphone. The optimum distance from the microphone  
is approximately 20 to 35 cm. The microphone pre-amplifier embodies a limiter to control signal peaks and  
protect the system against overdrive.  
The extension socket (EXT) allows connecting a second microphone with TALK button. Assigning the function  
(area, group) of the external microphone is performed during the configuration via PC.  
13 Display  
Depending on the actual operational status of the system, the LC-display with 2 lines of 16 characters each,  
shows information on time, operation mode, user notes, setting up, fault messages including precise device /  
module specification, etc.

5.2.5 Key-Labeling  
Labeling the keys of paging consoles is done using label-strips, which can be slid in from the side. The label-strips  
for the 6 or 8 function keys are slid in from the right while the selection key strips – for 10, 20, 30, or 50 selection  
keys – are inserted from left. Therefore, you have to detach the correspondent side panel (2 screws) and insert  
the labeled strip into the gap between the front panel and the front panel foil.  
The most convenient way of printing the labels is to utilize the word processing software MS-WORD. A suitable  
MS-WORD template file is supplied. Please note that with different printer models margin-settings may vary.  
Please adjust the layout form according to the individual specifications of your printer model.  
Tested printer models are:  
HP LaserJet 6P  
HP LaserJet 5  
HP LaserJet II  
The recommended paper thickness is between 120 g/m2 and 200 g/m2.  
Also supplied with this handbook are prepared label-strips in German, English and French as well as empty strips  
which only have to be cut out. You can label the empty strips in handwriting or by using Letraset® letters.

5.2.6 Operation  
This chapter explains all functions that are used during general operation.  
Selective Call  
The user can launch calls or announcements into freely selectable areas or groups.  
Pressing a single or several selection keys defines areas or groups where a call is launched into – corresponding  
LED’s will light. By pressing the key of an already pre-selected line once again deactivates that line and the  
corresponding LED goes out.  
After making a selection, pressing the TALK-button ignites the call. Prior hereto, the BUSY LED allows checking  
whether all lines and the paging station input are actually free. If single lines or the terminal input are busy with  
lower priority transmissions, the BUSY LED will blink slowly. Whilst making an announcement is possible, this will  
interrupt any other transmitted event. If single lines or the terminal input are busy with higher priority signals, the  
BUSY LED will vastly blink and the calling attempt is ignored (also refer to the description of indications).  
The BUSY LED lights during the transmission of an announcement. The TALK button has to be pressed during  
the whole message. Until the user makes any changes, the defined selection stays memorized, even after  
releasing the TALK button. Pressing the CANCEL key de-selects the entire selection.  
Additionally and in case of a pre-gong signal has previously been programmed, the GONG LED will light during  
the transmission of the pre-gong signal.  
Collective Call  
The announcement is launched into all areas of the entire installation.  
The procedure is similar to making a selective call. First, all areas of the installation are selected by pressing the  
ALL key. Pressing the TALK button activates the collective call. During the transmission of a call, all area and/or  
group LED’s as well as the ALL LED will light (also refer to the paragraph “indications”). The TALK button has to  
be pressed down until the end of the announcement. BUSY LED indication and the behavior of the pre-gong  
signal are equivalent to the selective call.  
Direct Call  
Principally, assigning a direct call to any selection key (area key, group key, ALL key) is possible via PC during  
the configuration procedure. This allows making an announcement directly by pressing the desired selection key  
– without need to press the TALK key. For direct calls the BUSY LED also signals the status of correspondent  
areas (free, busy with lower priority signal, busy with higher priority signal; see “indications”). When shipped, there  
is no factory pre-set direct call programmed.  
Gong (Chime) Signal  
By factory the Gong key is programmed as a general call  
A gong signal can also be transmitted into any selectable area or group of the entire installation (if programmed).  
First, the desired areas / groups have to be selected; either by use of the selection keys (selective gong) or with  
the ALL key (general gong). Pressing the GONG key releases the gong signal. While the gong signal is being  
transmitted, the GONG LED lights continuously or blinks (also refer to indications). The gong’s priority can be set  
to 6 or 7. Therefore it has priority over announcements from any paging station, except for the directing terminal  
(priority 10).  
Pressing the STOP key cancels the transmission of a gong signal.  
During setup mode this key is used to go back to the normal operating mode (escape).

DEVICE DESCRIPTIONS  
Text Message  
A text message recorded via the optional message module or using an external recording/playback device can be  
transmitted into any selectable area or group of the entire installation.  
First, the desired areas / groups have to be selected; either by use of the selection keys or via the ALL key.  
Pressing the TEXT key starts the reproduction of a prerecorded message that had been assigned during  
configuration. While the text message is being transmitted, the TEXT LED lights steadily or blinks (also refer to  
indications). The text message priority can be set to values between 2 and 8.  
Pressing the STOP key cancels the transmission of a text message.  
General Alarm  
A general alarm signal is always transmitted to all lines of the entire installation.  
Pressing the covered ALARM key launches the integrated alarm. The key lights during the transmission of the  
alarm signal. The priority of the alarm can be set between 7 and 9. Therefore it has priority over any  
announcement or other event, except for those that were ignited from the directing paging station (priority 10).  
Pressing the STOP key or subsequently pressing the ALARM key cancels the alarm.  
Selective Alarm  
When a paging station is equipped with a second ALARM key providing the option for selective alarms, it is  
possible to transmit alarm signals into selected lines.  
Similar to the procedure for making a selective call you first have to select areas or groups to which the alarm  
signal shall be transmitted. Afterwards, pressing the covered ALARM key starts the selective alarm. The key lights  
during the transmission of an alarm. Already now, you are able to enter the lines for the following alarm.  
Pressing the STOP key or subsequently pressing the ALARM key cancels the alarm.  
When shipped, there is no factory pre-set selective alarm pre-programmed.  
Note:  
The launch of an alarm does not depend on a paging console’s priority setting it had been  
activated from. Launching an alarm is possible from any microphone terminal at any time,  
even when the system is in stand-by mode. A running alarm is optically and occasionally also  
acoustically indicated at every paging station.  
Canceling Signals  
Pressing the STOP key cancels alarms, gong signals and text message transmissions. Events can only be  
terminated at the paging station they were launched from with the exception of the directing terminal (paging  
console with the highest priority possible 10). Through the directing station it is possible to cancel any signal in  
progress.

DEVICE DESCRIPTIONS  
System ON / OFF  
The ON key switches a PROANNOUNCE system ON or OFF. Mostly, it is not intended that any paging station be  
provided with the possibility to do so. Thus, this function can be programmed via PC-configuration.  
When the system is in stand-by mode, the ON LED is off. Pressing the ON key turns the PROANNOUNCE  
system’s power on which can take up to 10 seconds, while the ON LED is blinking. Once the system is ready for  
operation, the ON LED lights continuously (which also applies for all paging stations of the entire installation).  
To switch the system OFF, you have to press the ON key for approximately 1 second. This is to prevent  
inadvertently turning off the system.  
Pressing an ALARM key or igniting an alarm sequence at external terminals automatically switches the  
PROANNOUNCE system’s power on and boots the system.  
Program Assignment  
Activating this feature allows the assignment of programs to individual areas and groups of the entire installation  
during the PC-configuration procedure.  
First, by pressing the PROGRAM key, the paging station has to be set to program-assign mode. Pressing a single  
or several selection keys assigns the outputted program (background music) to the selected areas and groups.  
The corresponding LED’s are lit. Program transmission has always the lowest priority (1). The signal level is  
determined during system configuration. The assignment stays memorized until the selection keys are pressed  
again. Pressing the CANCEL key erases the entire assignment-pattern.  
Subsequently pressing the PROGRAM key or any other function key cancels program-assign mode. It is also  
automatically canceled after approximately 15 seconds.  
In single-program configuration the music reproduction into all areas of the installation is attenuated for the time of  
an announcement. In double-program configuration parallel transmission of a background music program into  
rooms that are not part of an actual announcement selection is possible as well. If every line incorporates its own  
LF-output and separate power amplifiers, mixing announcements and background programs is possible in any  
way.  
Special Functions  
Generally, assigning a function to each selection key is possible. This allows utilizing a paging station to control  
the lighting, door openers, blinds, etc.; even controlling volume settings is possible through the use of the UP /  
DOWN keys.  
When shipped, there are no special functions assigned.

5.2.7 Paging Console Configuration In Setup Mode  
Configuring paging consoles is preferably performed on the central unit via computer and using the  
PROANNOUNCE Designer software. This represents the most convenient way without any limitation, while a  
paging terminal itself offers only limited programming ability.  
Several key functions differ between setup-mode and operation mode. Alternate functions are marked on the right  
top corner of the individual key area.  
Pressing PROGRAM key and STOP key simultaneously for at least 1 second – the PROGRAM LED starts  
blinking – engages a paging station’s setup-mode.  
Note:  
Paging stations where program-assignment has been activated indicate the program  
assignment-pattern for a short period of time.  
Using the ‘<‘ and ‘>‘ keys lets you step through the setup menu items in forward and backward direction  
(parameter selection). Parameter number and name are shown on the display.  
The following table shows an overview of parameters and their meaning:

The ‘‘ and ‘‘ keys activate / deactivate corresponding parameters or increment / decrement according  
parameter values. For directly entering numerical parameters, use selection keys 1 to 10, where the 10-key  
represents the “0”.  
Pressing the ESC key returns to ‘normal’ operation. The setup-mode is also automatically canceled when for  
approximately 15 seconds no entry or change has been made. All parameters are automatically stored.  
1
Address  
Paging consoles accept the assignment of addresses between 1 and 16. The setting is generally performed  
using the numerical keys 1 to 10, where the 10-key represents the “0”. For paging stations without selection  
keys, the address has to be set using the ‘‘ und ‘‘ keys.  
CAUTION: When shipped all paging station addresses are set to OFF (no address). Therefore it  
is important to assign a correct address to a microphone terminal, before the first  
operation. Within an installation terminal addresses have to be assigned exclusively;  
a specific address can exist only once!  
When applying operation voltage for the first time, paging consoles start up in entry  
mode right away.

DEVICE DESCRIPTIONS  
2
Password (does not apply to paging consoles without selection keys)  
3 or 4-digit passwords provide protection for paging consoles against unauthorized operation. Password  
protection can be established in two levels. The first level is the ‘normal’ user-level. In case this level is  
password-protected, the paging station cannot be operated except for launching an alarm. The second level is  
the setup-level. If this level is password-protected, the setup-mode is not accessible while unlimited ‘normal’  
operation is possible.  
Level 1 and 2 passwords are assigned and transferred to the individual paging stations during the PC-  
configuration procedure. As factory preset the level 1 password is set to ‘111’ and the level 2 password is  
‘2222’; level 2 (setup-mode) is password-protected (factory pre-set).  
To prevent a paging station from unwanted access, you have to enter setup-mode and select parameter 2  
“password”. Depending on which function of the paging console you want to protect, by using the selection  
keys you have to enter either the 3-digit level 1 password or the 4-digit level 2 password. Protection is now  
activated and operation (1st level) and/or programming (2nd level) are not possible anymore. The blinking  
PROGRAM LED indicates this status.  
The protection is canceled by re-entering the correct password while being in setup-mode.

Pre-Gong Signal  
It is possible to program a pre-gong signal that is heard before an announcement. The pre-gong signal is  
transmitted into the selected areas when pressing the TALK-button. You can begin with your announcement  
during the transmission of the pre-gong signal; you can talk “into” the pre-gong.  
Using the arrow keys (<>) first select parameter 3. Now, you can ignite the pre-gong signal with the ‘‘ key or  
cancel it by using the ‘‘ key. The pre-gong function can also be activated or deactivated during PC-  
configuration.  
Buzzer  
The integrated buzzer can be programmed as acoustic alert signal. During failure, malfunction, or as general  
alert a buzzing sound is heard. When an alarm has been launched, the buzzing can be heard for the whole  
period of the alarm.  
First, select parameter 4 using the arrow keys (<>). Now, you can activate the buzzer by pressing the ‘‘ key.  
Pressing the ‘‘ key deactivates the buzzer. The buzzer function can also be activated during PC-  
configuration.  
Compressor  
The paging stations’ microphone pre-amplifier incorporates compressor / limiter circuitry. While the limiter is  
constantly activated, the compressor can be switched ON or OFF. When the compressor is engaged, low-  
level signals are amplified to a higher degree, which results in constant talking levels although the distance  
between the announcer and the microphone varies. Besides, you have to keep in mind that also  
environmental noise is amplified. Thus, on-site testing with and without compressor will reveal which results in  
the better performance.  
First, by using the arrow keys (<>), select parameter 5. Pressing the ‘‘ key activates the compressor.  
Pressing the ‘‘ key deactivates the compressor. It is also possible to activate the compressor during the PC-  
configuration procedure.  
6
7
Time / Date (does not apply to paging consoles without selection keys)  
The connected paging stations allow setting the date and time of the PROANNOUNCE system.  
First, by using the arrow keys (<>), select parameter 6. Using the selection keys 1 to 10 – with the 10-key  
representing the “0” – you can enter the correct time. Date and time are indicated in the following format:  
tt.mm.yy hh:mm. They have to be entered in that sequence  
LCD-Contrast  
Paging consoles with display allow the user to individually adjust LCD-contrast and viewing angle. This allows  
optimum legibility from the user’s location.  
First, by using the arrow keys (<>), select parameter 7. Now, you can adjust the LCD-contrast via the ‘‘ or ‘‘  
keys.

5.2.9 Priorities  
The PROANNOUNCE system allows setting 10 priority levels (highest priority = 10, lowest priority = 1) that  
include announcements, as well as alarm and gong signals, and vocal message reproduction. A higher prioritized  
event principally interrupts any other event with a lower priority setting. For events with equal priority the earlier  
launched signal is continued; has priority over the latter.

5.2.10 DPC 4350 Paging Station Extension  
The DPC 4350 paging station extension provides selection keys only. It is employed whenever a higher amount  
than 50 lines need to be accessed or when an installation’s requirement of group and special function keys  
exceeds the existing amount of selection keys. The DPC 4350 can be easily combined with any other paging  
station model. The following list shows the amounts of maximally accessible lines for various combinations:  
Combination  
Maximum amount of lines  
DPC 4106 + DPC 4350

The extension unit is directly connected to the extension interface of the main paging station using the supplied 8-  
pole RJ-45 cable and plugging it into the EXT-socket. A single paging station then consists of two devices that  
report to a common address. Therefore the central unit recognizes them as one single microphone terminal with  
an increased amount of selection keys. Also from the viewpoint of the user the two devices act as only one paging  
station; i.e. the selection keys of the main and the slave paging station provide equal access to their assigned  
areas, groups and special functions.  
Note:  
During the configuration of the system using the PROANNOUNCE Designer software, it is  
important that the main paging station’s EXT-socket is configured for the connection of a DPC 4350  
extension.  
The extension unit can only be operated together with DPC 45.. or DPC 40.. Series paging console  
models!

CAUTION: Install the switch so that the gap  
for changing the switch’s operation points  
towards the TALK key. This allows for easy  
changing its function even after it has been  
inserted.  
Note:  
Please make sure to solder the cables after the switch has been installed. Otherwise it is virtually  
impossible to slide the counter-nut over the body of the switch!  
4. Adjust the switch and tighten it using the supplied  
milled nut.  
5. Connect the cables and the resistor according to the  
circuit diagram on this page.  
6. Please mind the sequence in which you connect the  
flat wire cables. The two outside wires 1(rt) and 4(gr)  
need to be soldered to the contacts of the lamp. The  
two inner wires 2(gr) and 3(gr) need to be soldered to  
contacts 1 and 2 of the switch. Polarity of either pair  
of wires is not critical.  
7. Afterwards, you have to connect the 4-pole female  
plug to the corresponding OPTION 1 or OPTION 2 -  
terminal strip on the basic printed board assembly.

5.3.2 Instructions For Using Remote-Power Amps:  
1.  
2.  
Each power amplifier has to be set to the exact address as it is specified in the PROANNOUNCE Designer  
software (A=low value part, B=high value part). Address setting is performed using hexadecimal code.  
An RS-485 connection needs to be established between the DPM 4000 (remote socket) and maximally eight  
DCS 401, and maximally 64 amplifiers (DPA 4411 counts as a single unit). The RS-485 bus may not exceed a  
maximum length of 1,000m and must follow a line-structure with stub cables being as short as possible. When  
including more than 30 amplifiers, both ends of the bus have to be terminated with 120 ohms resistors. This  
bus is also used for monitor signal transmission.  
3.  
4.  
Connect the amplifier(s) to an operation voltage source.  
Perform a Netscan procedure via the PROANNOUNCE Designer software. In ‘normal’ operation the status-  
LED’s on the rear panel of the amplifiers have to light periodically, depending on the number of participants on  
the bus (communication with the DPM 4000).  
5.  
6.  
Within the communication window of the PROANNOUNCE Designer software checking which addresses are  
registered as participants is possible using the command “/AMP/AVLBL ?”.  
Once a participant on the bus had been disconnected from the DPM 4000 for a short term (e.g. because the  
RS-485 line had temporarily been disconnected), it is included again in the query sequence after 10 sec.  
5.3.3 Remote Module for Single-Channel-Amplifiers DPA 4120 and DPA 4140 NRS 90222  
This single-channel input module provides DPA 4120 or DPA 4140 power amplifiers with remote functionality.  
(For detailed information on DPA 4120 and DPA 4140 power amplifiers, please refer to the owner’s manual 355768.)  
The module allows connecting balanced XLR-input and XLR-thru lines as well as connection to the remote control bus  
of the DPM 4000 (RS-485). Prior to connecting the amplifier to the operating voltage, the unit’s address has to be set  
using the switches “A” and “B” (A=low value part)

rotary encoder  
A PROANNOUNCE installation allows integrating a maximum of up to 8 DCS 401 control modules. A single control  
module can host up to 12 relay boards of the types DCS 408 / DCS 409 in any sequence. Besides, it is possible to  
connect up to 5 logic input modules, 2 analog I/O modules, and 2 rotary encoders.  
The PROANNOUNCE operating system defines the total amount of supported control inputs and outputs. The  
PROANNOUNCE system can manage following amounts of different cards:  
S Control module DCS 401  
S Relays modules DCS 408 / DCS 409  
S Logic input module DCS 412  
S Analog I/O module DCS 416  
S Monitor module  
max. 8 boards  
= 16 rotary encoders  
max. 48 boards = 240 relays  
max. 10 boards = 120 logic inputs  
max. 8 boards  
= 128 analog inputs / outputs  
max. 1 per DCS 401  
Note:  
The power supply of individual boards can be provided either via RJ-45 connection (DCS 401), flat-  
wire cables (DCS 408, DCS 409, DCS 412, DCS 416) or via 2 binding posts (±24 V) that are  
located on each board. The current that runs through the RJ-45 connection or the flat-wire cables  
has not to exceed 1 A max. The current for modules that are connected to the DCS 401 via flat-  
wire cables may not exceed 700 mA max. The connectors CN7, CN8, CN9 share an electronic  
fuse. For higher currents, it is important that under all circumstances the binding posts are used  
instead. When cascading several modules, it is necessary to provide the power supply anew via  
binding post connection. Directly cascading up to 7 or 10 modules is admissible while taking power  
consumption features of the different types of incorporated modules into consideration. All modules  
need to be fed from a single power source! Data inter-exchange amongst modules has to be  
established via flat-wire cabling.  
CAUTION:  
For safety reasons, DCS 400 modules may only be installed in rack-shelf systems or enclosures  
that are locked and may only be opened by means of a tool (e.g. screw-driver, special key, etc.).  
When installing modules, make sure to follow all requirements of the EN60065:1993 regulation.  
Obeying the regulations for interference-emission (EN55022, class B) and interference-stability  
(EN50082-2), DCS 400 module printed board assemblies need to be grounded at their fixing points  
(e.g. using a metal bolt).

4. Before initial operation  
Connect a 24V source. Now, each DCS 401 control module verifies whether any local modules (DCS 408, DCS  
409, DCS 412, DCS 416) are connected, and if so, how many. The red LED blinks when the initialization process  
has not been performed yet.  
Only for DCS 401 control modules with software version previous to V1.1:  
Each  
DCS 401 control module is initialized by pressing the S2 button for approximately 3 seconds. Afterwards, the red  
LED has to light continuously signaling that initialization was successfully completed.  
Launch netscan (menu communication / netscan within the PROANNOUNCE Designer software). Now, the DCS  
401 modules are being initialized. Afterwards, the DPM 4000 runs a test verifying all addresses and recognizes the  
amount of DCS 401 control modules installed in the system. All components sharing the network are listed in the  
component list. This procedure takes approximately 20 seconds. Afterwards, the system is ready for operation.

APPENDIX  
6.2 DMM 4650 Interconnection  
Interconnecting the DMM 4650 is established through control inputs and outputs on the DPM 4000 or on the DCS 400  
monitoring system (DCS 408, DCS 409, DCS 412).  
Every single sequence needs a control output for the start / stop command and a control input for the transmission of  
the return signal. The control output starts the DMM 4650 sequence with a positive slope and stops it with a negative  
slope. The return signal's control input reacts to the negative slope and activates the macro "Message Stop".  
Additionally, in most cases a control input is needed for the DMM 4650 READY / FAULT signal. The following cabling  
example offers a possibility for controlling three different sequences including fault recognition. This is accomplished by  
utilizing Port A on the DMM 4650 and the 8 I/O control module (IN 5 - 8 and OUT 5 - 8) of the DPM 4000.

Using an adapter cable (2 x RJ-45 to 25-pole D-Sub), the shown cabling is established with relative little effort.  
For a larger amount of sequences, it is necessary to additionally utilize Ports B, C, and D on the DMM 4650. Triggering  
the sequence start / stop is accomplished through additional control outputs on the DPM 4000 control module (OUT 2 -  
4) or via relay contacts on the DCS 408 respectively on the DCS 409 modules. The return signal is present at the  
control inputs IN 1 - 4 of the DPM 4000 control module; additional control inputs can be provided via DCS 412  
modules.  
For controlling a DMM 4650 sequence, first you have to assign the start / stop and return message lines in the  
PROANNOUNCE Designer software. Afterwards, defining the audio signals in the window “External Audio Signals  
DMM 4650” is possible (the window opens when double-clicking onto the DMM 4650 symbol), where start / stop and  
return message lines are assigned to individual audio signals. When this is done, starting a DMM 4650 sequence from  
a paging console is already possible. Individual zones are assigned in the paging console dialog (key-assignment).  
Defining additional triggers and zones is possible for the case that different events than a paging station keystroke  
(external triggers, timer) are used to start a DMM 4650 sequence. Displaying text on the LCD during the output of a  
DMM 4650 sequence is possible as well.  
Programming examples for interconnecting the DMM 4650 are provided in the file Demo99_2.pmx, which is installed  
during the installation of the PROANNOUNCE Designer software within the following directory:  
/proannounce/examples/.
