Signal Silence Button
Activation of the Signal Silence button when the Panel is in Alarm, turns on the Signal Silence Indicator and
deactivates any Silenceable NACs. Non-Silenceable Circuits are unaffected. Signals will re-sound upon any
subsequent Alarm. This button does not function during any configured Signal Silence Inhibit Timer period. It also
does not function if the NACs are active as the result of a Fire Drill. In a Two Stage System, if the Auto General
Alarm Timer has timed out, this Signal Silence button also performs the same function as the Acknowledge button.
Fire Drill Button
The Fire Drill button activates all programmed and non-Disconnected NACs, but does not transmit any Alarms via
the City Tie, or Common Alarm Relay. Fire Drill may be programmed to operate specific NACs. Fire Drill is cancelled
by pressing the button again (toggle switch), or if the Panel goes into a real Alarm.
Acknowledge Button (Two Stage Only)
If the Panel is not configured for Two Stage Operation, this button does nothing. If the Panel is configured for Two
Stage Operation, activation of the Acknowledge button while the Auto General Alarm Timer is timing (there is an
Alarm in the Panel, but it is still in the First Stage), that timer is cancelled, and the Acknowledge Indicator is on
steady amber.
General Alarm Button (Two Stage Only)
If the Panel is not configured for Two Stage Operation, this button does nothing. If the Panel is configured for Two
Stage Operation, activation of the General Alarm button immediately sends the Panel into Second Stage - General
Alarm. It will also re-activate the Signals if they have been Silenced during General Alarm. The General Alarm
condition remains active until the Panel is reset.
Lamp Test Button
Activation of the Lamp Test button turns all front panel Indicators on steady in whichever colour they would normally
be activated and turns the buzzer on steady. If Lamp Test is active for more than 10 seconds, Common Trouble is
activated.
