SILENCE/ACKNOWLEDGE
SILENCE
The purpose of the bells and internal buzzer, is to alert persons of a potential fire danger. Once the fire's
location has been determined and appropriate measures are being taken, the firefighter may wish to silence
the internal buzzer and bells without having to totally reset the alarm.
When the buzzer and bells are operating, pressing the "SILENCE" key once will silence them, however if a
subsequent alarm arises, the buzzer and bells will be reactivated and a second silence operation will be
required to silence them.
When silenced, the "Buzzer Isolate" and "Bells Isolate" LEDS will flash. The re-activation of the buzzer and
bells will cause the "Buzzer Isolate" and "Bells Isolate" LED's to turn off.
If the buzzer or bells are already isolated, the isolate LED's will be illuminated continuously; pressing "silence"
will have no effect on the display.
If the buzzer or bell isolate LEDS are illuminated due to a "silence" operation, once the zone(s) in alarm is
reset, the isolate LEDS will be automatically turned off.
BUZZER ISOLATE
BUZZ

Depressing the "BUZZ ISOL" key will isolate the buzzer, the "buzzer isolated" LED will illuminate and the
buzzer will not sound until the buzzer is de-isolated. Pressing "BUZZ ISOL" for a second time will de-isolate the
buzzer.
BELL ISOLATE
BELL
ISOL
Depressing the "BELL ISOL" key will isolate the bells. The "bells isolated" LED will illuminate and the bells will
not sound until the bells are de-isolated. Pressing "BELL ISOL" for a second time will de-isolate the bell.
Opening the outer door of the panel when no alarms are present will automatically force a bells isolate
condition. This can be over-ridden by pressing bell isolate again, effectively de-isolating bells.
Opening the outer door of the panel when there is an alarm will have no effect on the bells.
Once the outer door has been closed, the bells will be placed in the de-isolated mode, regardless of their
previous state.
