to operate specific NACs. Fire Drill is cancelled by pressing the button again (toggle switch), or
if the Panel goes into a real Alarm.
8.2.7 General Alarm Cancel 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 Cancel 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 General Alarm Cancel Indicator is on steady amber.
8.2.8 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.
8.2.9 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.

Single Stage Operation
In a single stage system, all alarm inputs are treated in a similar manner. Alarm inputs include
any of the following: non-verified alarm, verified alarm, sprinkler alarm, water-flow alarm, and
general alarm circuits. Any of these alarm inputs occurring when the panel is not already in
alarm cause the following:
•
The buzzer sounds steadily
•
If fire drill is active, it is cancelled
•
The Common Alarm LED turns on
•
The Common Alarm relay activates if Aux disconnect is not active
•
The Auto Signal Silence timer, if configured, starts
•
The Signal Silence Inhibit timer, if configured, starts
•
All non-disconnected NACs programmed to the input are activated provided that Aux
disconnect is not active
•
Non-disconnected strobes associated with the input are activated
•
Non-disconnected signals associated with the input are activated at the evacuation rate
Subsequent alarms when the panel is already in alarm, cause the following:
•
The alert buzzer sounds steadily
•
If Signals have been silenced, they are resounded, the Signal Silence LED turns off, and
the Auto Signal Silence timer, if configured, is restarted
•
Any additional non-disconnected strobes associated with the input are activated
continuously
•
Any additional non-disconnected signals associated with the new input are activated at
the evacuation rate
