D2071A Operations & Installation Guide 1.0 Overview

1.0Overview

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.
