D2071A | Operations & Installation Guide |
1.0 Overview
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.
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.
1.1 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.
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.
1.2 RFI 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
1.6 Slave 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.
1.6.1 Slave 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.
1.6.2 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

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.
1.8.2 Programmer Connector (J3)
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.
1.8.4 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, 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.
