Supervisory
Zone 4 is always used for monitoring supervisory devices (such as valve tamper
switches). A short circuit on this zone (activation of a N.O. contact) will cause the
supervisory LED and the zone 4 yellow LED to flash. The piezo sounder will generate
a unique Pressing TONE SILENCE will silence the piezo and cause the supervisory
LED to illuminate steadily, but the Zone 4 Trouble LED will continue to flash.
Supervisory signals latch and require RESET to clear. The ALARM SILENCE switch
will silence the piezo, cause the supervisory LED to illuminate steadily and turn off the
Supervisory Notification Appliance Circuit. An open circuit on Zone 4 will be reported
as a zone trouble.
Zone Disable
If a zone has been disabled, an alarm
that occurs on that zone will flash the
red zone LED, but not the piezo or any
output circuit.
If both power sources
are removed from the system, all zones
will be re-enabled upon restoration of
power. Disable status will be lost.
The Zone Disable routine makes use of
the four panel switches as follows:
1. Press and hold in the TONE
SILENCE switch.
2. With the TONE SILENCE switch
held in, press (in sequence) the
ALARM SILENCE switch, the
ALARM ACTIVATE switch, and
then the RESET switch.
3. The Zone 1 Alarm LED will flash.
4. To disable Zone 1, press the RESET switch. The Zone 1 yellow LED will light to
show that the zone is disabled.
Note: The RESET switch toggles disable status for the selected zone.
5. To select the next zone, press the ALARM SILENCE switch.
6. To select the previous zone, press the ALARM ACTIVATE switch.
7. When disable selections are complete, release the TONE SILENCE switch.
If any zone has been disabled, the trouble relay will activate and System Trouble LED
will flash.
Last Event Recall
Last Event Recall allows the user to display the previous panel status. The last event
recall uses the four panel switches as follows:
1. Press and hold in the TONE SILENCE switch.
2. With the TONE SILENCE switch held in, press (in sequence) the RESET switch,
the ALARM ACTIVATE switch, and then the ALARM SILENCE switch.
3. Last Event is displayed.
4. Release the TONE SILENCE switch to return to normal operation.
Note: To clear the last event buffer, press RESET twice.
