9.10 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. If any of these alarm inputs occur when the panel is not already in
alarm, the following occurs:
• The buzzer sounds steadily
• If Fire Drill is active, it is canceled
• The Common Alarm Indicator turns on
• The Common Alarm, Auxiliary Alarm and all correlated relays activate if Auxiliary
Disconnect is not active
• The Auto Signal Silence Timer, if configured, starts. For UL installations, disable the
auto signal silence timer
• The Signal Silence Inhibit Timer, if configured, starts
• All connected relays 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
Pressing the General Alarm button on the panel also initiates a general alarm.
Subsequent alarms when the panel is already in alarm cause the following:
• The alert buzzer sounds steadily
