Optional Accessories

CA2Z module (Class A initiating device circuit)

Converts two Class B initiating device circuits to two Class A circuits.

CAM Module (Class A Indicating Appliance Circuit)

Converts indicating appliance circuit from Class B to Class A. One model CAM (Class A Module) is required for each circuit. (Do not use this on an output programmed as “TROUBLE BELL”.)

ARM-1/ARM-2 Module (Auxiliary Relay Module)

Activated by 24VDC Indicating and/or Releasing, polarity reversing circuits. The module provides a non-supervised DPDT Relay that can be used for fan shutdown, door release, elevator recall, etc.

RA-4410RC(Remote Annunciator)

Connects to RS-485 & 24VDC terminals. Provides 34 LED’s for each zone in alarm supervisory, or trouble, each output activated or in trouble, AC power, Power trouble, System trouble, Ground fault, Supervisory, Supervisory trouble, Alarm, Alarm silence and Pre-discharge/Discharge.

Basic Operation

In addition to the following events, the panel also provides an output via the RS-485 terminals to the RA-4410-RC remote annunciator to light the appropriate indicators. See remote annunciator operations, page 12. In addition, the remote annunciator has a silenceable buzzer that sounds on supervisory or trouble conditions.

Initiating Device Circuits Alarm Condition

An increase of current on any alarm initiating device circuit to approximately 10 mA or greater will result in the following:

Alarm (Except zones programmed as LOW AIR ALARM):

1)Activation of the common alarm relay contacts.

2)Activation of the output circuit(s) which are mapped to the initiating device circuit(s). Providing all zone(s) necessary for the activation of those circuits is in alarm

3)“ALARM” and zone # displayed on LCD.

4)Activation of the red ALARM LED in a flashing mode as well as corresponding zone. NOTE: The ALARM LED will continue to flash until the Signal Silence button is pushed. The silence button will remove power from all outputs set up as Indicating except those activated by zones programmed as Waterflow.

5)Activation of zones programmed as waterflow will operate the common waterflow relay contacts in addition to the above. Note: If Zone 1 is programmed as Firecycle, an open circuit will result in the above.
