The annunciator also has a lamp test switch.

ARM-44 (Relay Module) - Relay installs in a cabinet and provides 8 relays. 4 relays mapped to inputs and 4 relays mapped to the

outputs in a 1 to 1 relationship selectable selectable disable switch.

RCDS-1 (Release Circuit Disconnect Switch)

Provides physical means of disconnecting release circuits in compliance with NFPA 72, 2007, 6.12.5.2.

Basic Operation

In addition to the following events, the panel also provides an output via the RS-485 terminals to the RA-4410RC remote

annunciator to light the appropriate indicators. See remote annunciator operations, page 15.

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 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. “PRE-DISCHARGE” displayed on LCD if zone(s) in alarm activated pre-discharge timer (In chemical mode only).

5. Activation of red ZONE indicator(s) on LED display for the initiating device circuit(s).

6. Activation of red ALARM indicator on LED display.

7. Activation of red OUTPUT indicator(s) on LED display module for the output circuit(s) which are mapped to the

initiating device circuit(s).

8. Activation of ashing red PRE-DISCHARGE indicator on LED display if in chemical mode and pre-discharge timer

was activated by zone(s) in alarm. Providing all zone(s) necessary for the activation of those circuits is in alarm.

Low Air Alarm

1. Operation of supervisory relay contacts and local buzzer.

2. Activation of the notication appliance circuit(s) or releasing 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. LOW AIR ALARM and <CIRCUIT #> displayed on LCD.

4. Activation of yellow ZONE indicator on LED annunciator module for the initiating device circuit.

5. Activation of yellow ZONE indicator(s) on LED annunciator module for the initiating device circuit(s) described as

“LOW AIR ALARM”.

6. Activation of yellow OUTPUT indicator(s) on LED annunciator module for the output circuit(s) which are mapped to

the zone. Providing all zone(s) necessary for the activation of those circuits is in alarm.

7. Activation of the amber supervisory LED in a ashing mode. NOTE: The supervisory LED will continue to ash

until all events in the SUPERVISORY queue are viewed. This is accomplished by scrolling through all of the events by

use of the scroll up and scroll down buttons. The LED will go steady after all alarm events have been viewed.

Supervisory

An increase of current to approximately 8 mA or greater on the supervisory initiating device circuit(s) or disabling an output

programmed as realeasing will result in the following:

1. Operation of supervisory relay contacts and local buzzer.

2. Operation of any output circuits that have been described as SUPERVISORY BELL.

3. “SUPERVISORY”, “TAMPER”, “LOW AIR”, or “HIGH AIR” and <CIRCUIT> displayed on LCD.

4. Activation of yellow SUPERVISORY indicator on LED display.

5. Activation of yellow ZONE indicator(s) on LED display for the initiating device circuit(s) described as

“SUPERVISORY”, “TAMPER”, “LOW AIR SUPERVISORY”, or “HIGH AIR”.

6. Activation of yellow OUTPUT indicator(s) on LED display for the Notication appliance circuit(s)

described as SUPERVISORY BELL.

7. Activation of the amber SUPERVISORY LED in a ashing modes well as the corresponding zone LED. NOTE: The

SUPERVISORY LED will continue to ash until all events in the SUPERVISORY queue are viewed. This is accomplished by

When in CHEMICAL EXTINGUISHING mode, the release circuit(s), are not activated until the pre-discharge timer expires,

if a pre-discharge time was programmed. The predischarge time defaults to 30 seconds for Manual Release and 60 seconds for

all other alarm tones.
