Materials Included  
1.0 Overview  
The D2071A Fire Alarm Control Panel (FACP) is a  
three-zone digital alarm communicator transmitter  
(DACT) used in limited stand-alone applications or in  
off-premises monitoring of existing FACPs in slave  
applications.  
1.3.1  
D2071A  
The D2071A is shipped completely assembled and  
includes:  
Installation literature  
Zone 1 is a Class A” (NFPA Style D) alarm initiating  
circuit. It can monitor waterflow or other alarm  
initiating devices in a stand-alone application. Zone 1  
can also monitor an alarm output in a slave application.  
End-user information label  
15 in. (2.7 cm) double-sided adhesive strips (2)  
Mounting screws and washers (2)  
Strain relief cable tie (1)  
Zones 2 and 3 are Class “B” (NFPA Style A)  
supervisory circuits that monitor sprinkler supervision  
devices such as valve tampers in a stand-alone  
application or trouble outputs in a slave application.  
32 in. (81 cm) dual connector battery leads  
1.8 kend-of-line (EOL) resistors for Zone 2 and  
Zone 3 supervision circuits (2)  
Primary and alternate telephone outputs allow the  
D2071A to communicate to the central station or remote  
station. A built-in telephone line supervision circuit with  
trouble buzzer, LED, and optional Form “C” Relay  
provides local telephone line trouble annunciation for  
both telephone lines. The D2071A also provides an  
optional Form “C” Relay output for alarm annunciation  
on the alarm initiating circuit.  
1.3.2  
D2071AC  
The D2071AC Kit include the D2071A and:  
Installation literature  
End user information label (1)  
Mounting screws and washers (2)  
Strain relief cable tie (1)  
The D2071A is housed in a red plastic, nonconductive  
enclosure that insulates the device from surrounding  
circuit boards or metal surfaces. You can mount the  
D2071A in fire alarm control enclosures specified in  
Table 1 on page 5.  
32 in. (81 cm) dual connector battery leads  
1.8 kEOL resistors for Zone 2 and Zone 3  
supervision circuits (2)  
D4103R Enclosure (1)*  
D161 Telephone Cords (2)  
Conduit support washers (2)  
1.1  
Communicator  
The D2071A uses a built-in communicator to transmit  
reports to a digital receiver. Two RJ31X or RJ38X jacks  
connect to two separate telephone lines for primary and  
alternate transmissions. The D2071A has full telephone  
line seizure and complies with FCC regulations for  
using the public telephone network.  
* The D4103R includes a D2002 Mounting Plate and a Basler  
Electric Transformer (Model A9115 [P/N: 58-06306-000])  
installed in the enclosure. This transformer is Underwriters  
Laboratories, Inc. (UL) recognized, Class II rated for 20 VA at  
12 VAC. It uses pigtails to hard wire directly to a 110 VAC or  
120 VAC power source.  
You must program two receiver telephone numbers for  
the D2071A. Initially, the communicator attempts to  
transmit reports to the primary telephone number. If it  
cannot, the communicator switches to the alternate  
number. Reports are transmitted to the receiver in  
binary frequency-shift keying (BFSK) format or pulsed  
fast single round format. The communicator only  
accepts the 2300 Hz acknowledgment tone. It is  
compatible with most major digital receivers that accept  
the BFSK or Pulsed Fast Single Round format, and  
generates a 2300 Hz acknowledgment tone.  
1.4  
Required Materials  
Table 1 lists additional parts necessary to install the  
D2071A.  
1.5

For slave communicator applications, connect the  
D2071A to a 24 VDC FACP.  
Do not install a battery in this configuration.  
Do not connect the D2071A to a 12 VDC  
power supply or a control panel that only  
provides 12 VDC output.  
1.8.1  
Terminal Strip  
The terminal strip (Item 1 in Figure 1 on page 7)  
connects system wiring for power, ground, a Class A”  
Alarm Initiating Circuit, two Class “B” supervisory  
circuits, and two Form “C” Relay outputs.  
If the FACP does not provide a 24 VDC auxiliary  
power output, you must use a D126 Battery, a D1220  
Transformer, and a D8004 Transformer Enclosure.  
1.8.2  
Programmer Connector (J3)  
If using the D2071AC, the Basler Electric Model A9115  
Transformer (P/N: 58-06306-000) installed in the  
D4103R Enclosure replaces the D1220 Transformer and  
the D8004 Transformer Enclosure. This is a UL  
recognized, Class II transformer rated for 20 VA at  
12 VAC. It uses pigtails to hard wire directly to a  
110 VAC or 120 VAC power source.  
Connect the D5100 or D5200 Programmer to the J3  
programmer connector (Item 2 in Figure 1).  
1.8.3  
D2071A Enclosure Cover  
The D2071A Enclosure Cover (Item 3 in Figure 1) slides  
open approximately 2 in. (5.1 cm) to expose the terminal  
strip, programming jack, and two Form “C” Relay  
sockets. You do not need to completely remove the  
cover during installation or for service.  
1.6.2  
UL Listed Enclosure  
Unless the monitored FACP is specifically listed or  
approved for use with the D2071A installed in the same  
enclosure, install the D2071A in a separate UL Listed  
enclosure. Connect the separate enclosure to the FACP  
by a conduit that is no more than 20 ft (6 m) long. The  
D4103R, D8109, and D8108A are all suitable for this  
purpose. The D2071AC includes a D4103R with a Basler  
Electric, UL recognized, Class II, hard wire transformer  
rated for 20 VA at 12 VAC mounted in the enclosure. It  
uses pigtails to hard wire directly to a 110 VAC or  
120 VAC power source.  
1.8.4  
Phone Line Trouble Buzzer  
The Phone Line Trouble Buzzer (Item 4 in Figure 1)  
sounds when either the primary or the alternate  
telephone line is in a trouble condition, or when  
communications failure occurs. Ten failed attempts to  
transmit any report puts the control panel in  
communications failure. The Phone Line Trouble LED  
and Phone Line Trouble Relay follow the Phone Line  
Buzzer.  
The buzzer, LED, and relay deactivate after a trouble  
condition occurs on the telephone line and the receiver  
acknowledges the Phone Line Trouble Report, or when  
the line returns to normal. If the D2071A attempts to  
transmit the Phone Line Trouble Report ten times  
without acknowledgment from the receiver,  
1.7  
Receiving Equipment  
The D2071A must report to compatible, UL Listed  
receiving equipment that meets the following processing  
capabilities:  
Fire alarm  
communication failure occurs.  
System trouble  
Low battery  
24-hour test  
If the D2071A is in communication failure, either the  
primary or alternate telephone line must be detected as  
normal and a report acknowledged by the receiver  
before the buzzer deactivates.

To determine the circuit’s electrical condition:  
2.1  
Earth Ground Wiring  
1. Ensure the D2071A is powered up and the loops are  
in a normal condition.  
Only use Terminal 3, not telephone or  
electrical ground, for earth ground  
connections.  
2. Use a multimeter to measure the voltage across the  
terminal connections. Connect one lead of the  
multimeter to a negative (-) terminal (6 or 7).  
Connect the other lead to a positive (+) terminal (8  
or 9).  
2.1.1  
12 VAC Mode  
To prevent damage from electrostatic charges or other  
transient electrical surges, use 16 AWG (1.5 mm) wire to  
connect the D2071A to earth ground at Terminal 3  
before making other connections to the control panel. A  
grounding rod or cold water pipe are good earth ground  
references.  
The measured zone input voltage reading for the  
electrical condition multimeter is Normal when  
Terminals 7 and 8 equal 1.0 VDC to 1.9 VDC, and  
Alarm (shorted) when Terminals 7 and 8 equal  
0.0 VDC to 0.3 VDC.  
2.2.2  
Retard and Reset Times  
2.1.2  
24 VDC Mode  
When the D2071A is connected to an  
FACP 24 VDC output, do not connect  
Terminal 3 to earth ground. This might  
cause a continuous ground fault condition  
on the FACP.  
Only use the Zone 1 retard or reset feature  
for waterflow switches and controls without  
their own retard and reset features.  
The retard timer prevents false alarms from conditions  
such as water supply surges in wet pipe sprinkler  
systems. These surges can occur during a brief  
activation of a waterflow alarm switch. The value you  
enter in Retard Time determines the length of time the  
waterflow switch remains activated before an Alarm  
Report is initiated. Generally, a 15-sec retard is adequate,  
but a longer interval might be necessary during  
extended surge conditions.  
2.2  
Zone 1, Alarm Initiating Circuit  
Use Terminals 6, 7, 8, and 9 for Zone 1  
alarm initiating circuit connections.  
Zone 1 is a four-wire, Class A” initiating circuit. You  
can connect up to five waterflow alarm switches or up to  
100 mechanically operated devices such as heat  
detectors or manual pull stations to this zone. NFPA 72  
requires you to connect a single pull station with  
waterflow switches. The AHJ might specify the location  
of this pull station. Other than this exception, do not  
combine waterflow switches with other types of devices.  
Reset Time is the parameter that compensates for  
sprinkler alarm valve fanning conditions in wet pipe  
systems with unique hydraulic problems. Fanning occurs  
when a sprinkler head activates or the inspector’s test  
valve opens and the waterflow switch does not activate  
long enough to overcome the retard time, but the  
waterflow switch cycles between alarm and normal  
conditions.  
Unlike the two-wire Class “B” circuits supervised by  
EOL resistors, the double loop Class A” circuit  
provides alarm response from all initiating devices with  
a single open or ground fault condition on the circuit.  
Connect the initiating devices to the D2071A as shown  
in Figure 2 on page 8 and Figure 3 on page 9.  
The retard and reset timers work together as follows:  
The retard timer tracks the time the alarm initiating  
circuit is in the alarm condition. It begins counting  
when the circuit enters the alarm condition.  
The reset timer determines when the retard timer  
resets to zero. When the alarm initiating circuit  
enters a non-alarm (restored or trouble) condition  
after being in the alarm condition, the retard timer  
stops at its current value and the reset timer begins  
counting.  
The D2071A has programmable retard (retard time) and  
reset (reset time) timers for waterflow alarm installations  
on wet pipe sprinkler systems. These timers compensate  
for water pressure surges and sprinkler alarm valve  
fanning conditions.  
If another alarm condition is detected before the  
reset timer reaches the value entered in reset time,  
the retard timer resumes counting from where it  
stopped and the reset timer is set to zero.  
2.2.1  
Class “A” Circuit Parameters  
The maximum resistance on the Class A” circuit sensor  
loop wiring is 100 per loop (between A1 and A2  
100 maximum, between B1 and B2 100 maximum).

Installation  
If the time specified in the retard time accumulates in 2.3.1  
Mode 1  
one or more successive alarm activations, the  
D2071A transmits an Alarm Zone 1 Report and  
activates the Alarm Relay.  
In Mode 1 (Figure 4 ) the loops are configured for NC  
devices only, no EOL resistor is used. The loops are not  
supervised for troubles. This mode is not acceptable for  
the stand-alone applications.  
The retard timer resets to zero only when the circuit  
remains in a non-alarm condition (restored or  
trouble) for the time entered in reset time.

When the alarm initiating circuit is normal for the  
time specified in reset time, the D2071A sends a  
Restoral Zone 1 Report.

Secondary Power Supply and  
Charging Circuit (12 VAC Mode Only)  
NFPA 72 applications require 110 VAC or 120 VAC,  
60 Hz commercial power for the transformer to be  
unswitched and from a reliable source. NFPA 72  
applications need a dedicated branch circuit to supply  
the 110 VAC or 120 VAC transformer power. Identify  
the method of disconnecting the circuit as a fire alarm  
control circuit. Only authorized personnel can  
disconnect the circuit.  
Use Terminals 4 and 5 for secondary power  
supply and charging circuit connections.  
2.7.1  
Battery  
The D2071A’s charging circuit is only calibrated for  
lead-acid type batteries. Do not connect D2071A to a  
battery when it is using 24 VDC from an existing  
FACP. The battery supplies power to the system during  
interruptions in primary power (AC) while in 12 VAC  
Mode.  
Never share the transformer with other  
equipment. Foreign grounds on the AC input  
damage the D2071A power circuit.  
For NFPA 72 applications, use a 12 VDC, 2.3 Ah,  
sealed, lead-acid, rechargeable battery (Model D1219).  
You can also use a 12 VDC, 7 Ah, sealed, lead-acid,  
rechargeable battery (Model D126) that exceeds the  
standby requirements.  
2.6.2  
24 VDC Mode  
Connect a 24 VDC, uninterrupted, regulated, auxiliary  
output from an FACP to Terminals 1 and 2. Set the  
12 V Mode to NO. Terminals 1 (+) and 2 (-) are polarity  
protected when the D2071A is programmed for the  
24 VDC Mode.  
Installation  
1. Install the battery in an upright position at the base  
of the metal enclosure.  
Do not connect a 12 VDC standby battery  
and do not connect earth ground to the  
D2071A when it is in 24 VDC Mode.  
2. Use the black lead to connect the negative side  
(black) to the D2071A Terminal 4.  
The discharge and recharge schedule in Table 4 shows  
the voltages at Terminals 1 and 2 used to generate  
Battery Reports with the D2071A in 24 VDC Mode. If  
the voltage falls below 11.1 VDC, the D2071A does not  
operate.

second D161 or D162 Phone Cord to connect the  
alternate telephone line to the D2071A Modular Jack  
(J2).  
The buzzer, LED, and relay deactivate after a trouble  
condition on the telephone line when the receiver  
acknowledges the Phone Line Trouble Report, or when  
the line returns to normal. If the D2071A attempts to  
transmit the Phone Line Trouble Report ten times

2.8.4  
Call Routing  
After one failed attempt to transmit a report, the  
D2071A tries to transmit a TROUBLE ZN E Report in  
addition to the original report. After two failed attempts  
to reach the receiver, the D2071A switches from the  
primary to the alternate telephone line. During the  
switch, the D2071A tries dialing even if you did not  
program an alternate telephone number.  
If the telephone company makes changes in  
its communications facilities, equipment,  
operations, or procedures that can affect  
communicator performance, the telephone  
company is obligated to notify the user in  
writing.  
The D2071A continues alternating between the primary  
and alternate lines for a total of ten attempts. If the  
D2071A cannot make contact with the receiver after ten  
attempts, it goes into communications failure and  
activates the Phone Fail LED, Phone Line Trouble  
Buzzer, and Phone Line Trouble Relay (if installed). The  
time from the first attempt to the communications  
failure is up to 10 min.  
2.9  
Cable Tie Installation  
After making the necessary connections, secure all wires  
from the D2071A to the strain relief tab:  
1. String the cable tie through the middle of the  
H-shaped strain relief tab.  
2. Group the wires attached to the D2071A, ensuring  
RESTORAL ZN E is the only report transmitted after a  
communications failure. Any report in the D2071A  
buffer before a communications failure is not  
transmitted. The buffer is cleared.  
no wire is disconnected (Figure 9 on page 17).  
3. Wrap the cable tie around the wires and firmly  
secure the tie to the strain relief tab (Figure 10 on  
page 17).  
For all applications, program both a primary and an  
alternate telephone number using different numbers.

Program Modules  
4.0 Program Record  
Unlike larger Bosch products, the D2071 Product  
Handler does not group program items in program  
modules. When you enter the 2071 program, you are in  
the Program Item Level.  
The 2071 Program Record selects several functions of  
the D2071A DACT, including the account number that:  
identifies the location during communication,  
decides how the telephone number is dialed,  
determines how the D2071A is powered, and  
controls the loop response times.  
3.9  
Editing the Program Record  
Each D2071A DACT programming option is listed as it  
appears in the Programmer Display. The default, a set of  
selections, and a description follows.  
Account #  
Default:  
Blank  
The selections are the only entries available for a  
particular program option. For example, Account #  
only uses numbers 0 through 9, letters B through F, or  
no entry. Do not use unlisted entries.  
Selections: 0 to 999, BBB to FFF, or Blank  
Ensure all entries are right-justified. The blank entry,  
equaling no account number, sends 000 in pulse that  
sends nothing in the BFSK format.  
To edit program options, change the entry and press  
[ENTER]. If the entry is valid, the programmer moves  
the cursor to the next prompt. When all program  
options in the record are edited, the programmer returns  
to the first program option in the record.

Maintain a short between Loop ”A”  
(Terminals 6 and 7) and Loop “B”  
(Terminals 8 and 9) for at least the  
time programmed in Retard Time.  
When a TROUBLE ZN 9 Report occurs in 12 VAC  
Mode:  
1. Confirm there is at least 12 VAC on Terminals 1  
and 2.

devices connected  
to the circuit  
Time.  
2. Ensure the outlet the transformer is plugged into  
meters between 110 VAC and 120 VAC.  
An open or ground on the circuit  
causes a Trouble Report.  
3. Confirm the output for the transformer connected to  
Terminals 1 and 2 is rated for 12 VAC and at least  
20 VA.  
Remove the circuit loops from the  
D2071A and meter them for  
continuity. There should be no  
more than 100 resistance  
between the wires that connect to  
Terminals 6 and 7 and between  
the wires that connect to  
normal.  
4. Disconnect the transformer from Terminals 1 and 2  
and meter the battery at Terminals 3 and 4. A fully  
charged battery should show 13.8 V.  
Terminals 8 and 9.  
5. Ensure the battery is a 12 V sealed, lead-acid type. It  
should be rated at 2.3 Ah or 7 Ah or greater,  
depending on the NFPA classification of the  
installation.  
With the wires for the circuit  
loops still removed from the  
D2071A, meter them for  
continuity to ground.

D2071A to confirm the Class “B”  
Mode is correctly programmed.  
3. Confirm Terminals 4 and 5 are not connected to a  
battery.  
An open on the circuits causes a  
Trouble Report for Modes 2 and 3,  
and an Alarm Report for Mode 1. A  
ground can cause an Alarm Report  
for Modes 2 and 3.  
4. Confirm program item 12 V Mode is set to NO.  
Remove the circuit loops from the  
D2071A and meter them for  
continuity. There should be no  
more than 100 plus the value of  
the resistors in the circuit  
between the wires that connect to  
Terminals 10 and 11, or between  
the wires that connect to  
Terminals 11 and 12.  
With the wires for the circuit  
loops still removed from the  
D2071A, meter them for  
continuity to ground.
