BASIC CIRCUIT OPERATION
DESCRIPTION OF SEQUENTIAL MODE:
Actuation of one detector in any one zone will create an alarm condition. Actuation of a second detector in the same zone will
start the pre-discharge timer (this mode is usually used with smoke detectors).
DESCRIPTION OF CROSS-ZONING MODE:
Actuation of one or more detectors in any one zone will create an alarm condition. Actuation of one or more detectors in both
zones, in addition to creating an alarm condition will start the pre-discharge timer. This mode is usually used with smoke
detectors.
ALARM CONDITION:
Provided all associated switches are in their normal condition an increase of current on any alarm initiating device circuit to
approximately 15mA or greater will result in the following:
1)
The zone or zones that have been activated will be displayed along with the word “ALARM” on the alpha-numeric
display.
2)
Operation of the red alarm LED.
3)
Operation of the auxiliary alarm contacts.
4)
Positive 24 VDC will appear on the associated zone electronic output terminal.
5)
Operation of one or both of the indicating appliance circuits depending on how they are programmed.
TROUBLE CONDITIONS:
Microprocessor failure: The yellow “System Trouble” indicator will be on; the “Trouble” buzzer will be pulsating and you will
be unable to silence the buzzer by operating the trouble silence switch. To silence the buzzer, disconnect the battery and turn off
the AC power. After 30 seconds reapply power. If the trouble still exists, call the factory. The supervision of the microproces-
sor is a safeguard feature that is built into the panel.
Other System Trouble: System trouble conditions will result in the following common trouble indications.
1)
Operation of the system trouble LED.
2)
Operation of the built-in trouble buzzer.
3)
Operation of the auxiliary trouble contacts.
INITIATING DEVICE CIRCUITS RESPONSE:
A decrease in current to approximately 3 mA or operation of the zone disable switch to the disable position on any initiating
device zone will result in the following:
1)
The zone or zones that are affected will be displayed along with the word “TROUBLE” on the alpha-numeric display.
If more than one trouble condition exists the conditions will be alternately scrolled every 2 seconds.
2)
Operation of all of the common trouble outputs (see “Common Trouble Outputs”).
