DESCRIPTION:

The zone card ZC-91A provides two Class A/B alarm initiating device circuits configured for alarm monitoring. Each zone is indi-

vidually equipped with alarm (red) and trouble (yellow) indicators for immediate status identification. This card plugs into the sec-

ond edge connector slot of the Main Board (MB-91A/M) and/or any Expander Board module (EB-91A/M)

Operation:

Alarm - A shorted detection circuit will initiate the panel into an alarm condition. The detection zone “ALARM” (red) indicator

will light steady and the “SYS. ALARM” (red) indicator on the Control Card (CC-91A) will activate. The common alarm contacts

on the MB-91A will transfer, and both general alarm Notification Appliance Circuits will operate.

Alarm Point Location

- In metered systems, once a zone is in alarm depress and hold down the respective zone switch (SW1 or

SW2) to display zone alarm point location of corresponding zone. Depressing switch will transfer alarm point location onto alarm

point location digital display (PWM-1000-2).
