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.
WARNING
Do not silence signals until all occupants are
evacuated to a safe area.
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 zones.
Low Air Alarm
1. Operation of supervisory relay contacts and local buzzer.
2. Activation of the notification 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 flashing mode. NOTE: The supervisory LED will continue to flash 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 releasing 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 Notification appliance circuit(s)
described as SUPERVISORY BELL.
7. Activation of the amber SUPERVISORY LED in a flashing modes well as the corresponding zone LED. NOTE: The
SUPERVISORY LED will continue to flash 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
supervisory events have been viewed.
