5.3 Waterflow Alarms
If the Waterflow Silence option is turned off (see 6.3.5 Waterflow Alarms Programming on
page 47), when a waterflow zone (type 03) initiates an alarm the NACs cannot be silenced
until all waterflow zones are returned to normal. If all waterflow zones return to normal after the
30 minute automatic signal silence timer has expired, then the panel will silence the NACs.
If the Waterflow Silence option is turned on, then an alarm on a waterflow zone is treated like
any other fire alarm.
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.
5.4.1 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.
5.4.2 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.
5.4.3 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.
5.5 Trouble Operation
When a trouble occurs, if there is a corresponding trouble LED it turns on steady. The common
trouble LED and the trouble relay also turn on. If no alarm is present on the system, the buzzer
will sound at a rate of ½ second ON/OFF. The buzzer and trouble LEDs will remain on until the
trouble is restored. If the Silence Trouble button is pressed, the buzzer turns off. Subsequent
troubles will resound the trouble buzzer.
Note: If there is no trouble present in the system then pressing the Silence Trouble button will result in
a 1 second error tone.
