9.6 Fire Alarm Operation
In a basic system set up all alarm inputs are treated in a similar manner. Alarm inputs include
any of the following: Non-Verified Alarm, Verified Alarm, Sprinkler Alarm, and Water flow
Alarm. 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 cancelled
• The Common Alarm Indicator turns on
• The Auxiliary 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 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
Subsequent alarms when the panel is already in alarm cause the following:
• The alert buzzer sounds steadily
• If Signals have been silenced as a result of the Signal Silence button or the Auto Signal
Silence Timer, Signals are resounded as they were before Signal Silence, the Signal
Silence Indicator is turned off, and the Auto Signal Silence Timer, if configured, is
restarted
• Any additional non-disconnected strobes associated with the new input are activated
continuously
• Any additional non-disconnected signals associated with the new input are activated at
the evacuation rate
