5.4 Supervisory Zone Alarms

When an alarm occurs on a supervisory zone (type 04), the corresponding zone supervisory LED begins
flashing. The common supervisory LED and supervisory relay (supervisory relay is optional) turn on steady,
and the buzzer turns on steady. If there was a trouble on that zone, the zone trouble LED turns off. The buzzer
remains on until the trouble silence button is pressed. Once the buzzer is silenced any flashing zone
supervisory LEDs turn on steady. The zone supervisory LEDs, common supervisory LED and supervisory
relay remain on steady until a system reset is performed.
Subsequent Fire Supervisory
After silencing a fire supervisory, a subsequent fire supervisory from another zone will resound the trouble/
supervisory buzzer and the new zone supervisory LED flashes until the Silence Trouble button is pressed.
Supervisory / Trouble Priority
If a supervisory zone has a trouble and it goes into alarm, the zone trouble LED is extinguished until that zone
is restored and the panel has been reset. The common trouble LED will remain on steady until all supervisory
alarms have been restored and the panel reset. All other 'common' trouble indicators will operate normally.
Supervisory / Fire Alarm Priority
The supervisory zone LED, the common supervisory LED and the buzzer (in the steady supervisory mode)
function normally whether there is a fire alarm present or not.
