The D2071A Fire Alarm Control Panel (FACP)
generates, uses, and can radiate radio frequency energy.
If this device is not installed according to the
manufacturer’s instructions, it can cause interference to
radio communications. The D2071A was tested and
complies with the specifications in Subpart J of Part 15
of Federal Communications Commission (FCC) Rules
for Class “B” Computing Devices.
If the D2071A interferes with radio or television
reception, determined by turning the radio or television
on and off, correct the interference by one or more of
the following:
•Reorient the radio or television antenna.
•Connect the AC transformer to a different outlet so
the D2071A and radio or television are on different
branch circuits.
•Relocate the D2071A with respect to the radio or
television.
If necessary, consult an experienced radio and television
technician for additional suggestions on correcting
interference. You can also send for the FCC’s InterferenceHandbook (stock no. 004-000-00450-7) at:
U.S. Government Printing Office
Washington D.C. 20402
The D2071A Control Panel is registered with the FCC
under Part 68 for connection to the public telephone
network using an RJ31X or RJ38X jack installed by
your local telephone company.
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.
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.
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.
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.
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.
1.1Communicator
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.
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.
1.2RFI and Lightning Protection
The D2071A resists radio frequency interference (RFI)
and high-voltage surges common to lightning areas.
Spark gaps and metal oxide varistors (MOVs) give the
D2071A additional electrical protection.

1.0 Overview
1.6Slave Communicator Applications
To use the D2071A as a slave communicator that only
provides signaling connections, connect the D2071A to
an existing UL Listed NFPA 72 FACP. Use the D2071A
in compliance with NFPA standards to provide:
•NFPA 72 central station connections for an existing
FACP when only a summary alarm and up to two
trouble signals are required, and
•NFPA 72 remote station signaling connections for an
FACP listed for NFPA 72.
1.6.1Slave Application Power
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.
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.
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.
1.6.2UL 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
120 VAC
power source.

Construction
1.8.1Terminal 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.
1.8.2Programmer Connector (J3)
Connect the D5100 or D5200 Programmer to the J3
programmer connector (Item 2 in Figure 1).
1.8.3D2071A 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.
1.8.4Phone 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,
communication failure occurs.
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.
