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 !

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.

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.

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.

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.

DEVICE DESCRIPTIONS

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.

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.

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

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

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.

90215

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.

2. Phantom Power

By closing the jumpers JP1, pins 1-2 and pins 3-4 (IN A) respectively JP2, pins 1-2 and pins 3-4 (IN B), it is

possible to (separately) engage 24 V phantom power when a microphone is connected to the corresponding

input. When shipped, jumpers are set to “open” (no phantom power).

3. Compressor / Limiter

The MIC / LINE input channels embody compressor / limiter circuits, which can be incorporated in the signal

paths via the jumpers JP3 for IN A and JP4 for IN B (position “COMP”), if needed. Normally, the compressors /

limiters should be used to eliminate the risks of overdrive and clipping, when directly connecting microphones.

When shipped, the jumpers are set to “LIN”.

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.

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.

5.1.11 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:

DPC 4106

DPC 4510

DPC 4520

DPC 4530

DPC 4550

6 function keys

8 function keys + 10 selection keys + alarm key

8 function keys + 20 selection keys + alarm key

8 function keys + 30 selection keys + alarm key

8 function keys + 50 selection keys + alarm key

DPC 4350

paging console extension with 50 selection keys

All paging consoles include the following common features:

all functions are processor-controlled

configuration data is stored in non-volatile FLASH RAM

condenser microphone with pre-amplifier and compressor / limiter circuitry

freely programmable key-assignment

easy key-labeling through label-strips and MS WORD™ templates

analog circuitry surveillance via integrated pilot tone generator

processor surveillance via watchdog function

line surveillance via pilot tone and polling functions

covered alarm key (not with DPC 4106)

additional alarm keys or key-locked switches can be optionally retrofitted

connection of an external PTT-microphone or audio source

piezo buzzer for acoustical alerts

an optional loudspeaker can be retrofitted

setup-mode allows direct parameter setting at the paging station

two-line LC-display

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.

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).

DEVICE DESCRIPTIONS

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).

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).

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).

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.

DEVICE DESCRIPTIONS

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.

5.2.4 Connections

LAN socket

This is the interface for connecting DPC 4000 Series paging stations to the PROANNOUNCE system. The 8-

pole RJ-45 connector provides power supply, control interface RS-485, and audio connections. The

microphone terminal has to be connected to a corresponding RJ-45 wall outlet using the supplied connection

cord (3 m). The following figure shows the pin-assignment of LAN socket and RJ-45 network cable. Please

also pay attention to chapter 5.2.14 Cable Lengths.

figure 5.36

LAN socket and RJ-45 network cable pin-assignment

EXT socket

Mostly, this socket is used for connecting a DPC4350 paging station extension. Use the supplied network

cable (0.5 m) to connect the DPC4350 to the paging console’s EXT socket.

In case no paging station extension is being connected, utilizing the EXT socket for connecting a second

microphone with TALK button or other external audio signal sources to the paging console is possible as well.

Detailed information is provided in chapter 5.2.13 Optionally Available Accessories.

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/m²and 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.

DEVICE DESCRIPTIONS

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:

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.

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

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.

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

DPC 4510 + DPC 4350

DPC 4520 + DPC 4350

DPC 4530 + DPC 4350

DPC 4550 + DPC 4350

100

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!

5.3.2 Instructions For Using Remote-Power Amps:

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.

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).

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)

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).

When configuring and initially operating the DCS 400 system, please proceed as follows:

1. Cabling

➨ Use the supplied flat-wire cable for connecting the relay modules DCS 408, DCS 409 in the desired order to the

control module DCS 401. Mixed installation of relay modules is possible; numbering the relays is type-specific and

has to be performed according to their sequence.

APPENDIX

2. Voltage Supply

➨ Insert bridges serve to select the voltage supply connector of different modules. Please refer to the corresponding

description of individual modules or to their block diagrams.

CAUTION: The maximum current handling capacity of RJ-45 connections and flat-wire cables has to be

observed under all circumstances!

3. DCS 401 Addresses

➨ Using the Dip switch S1, the addresses of all connected control modules DCS 401 have to be set to different

numbers (addresses 0 - 7).

Dip switch S1

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.

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/.
