9.6 Fire Alarm Operation
In a basic system, 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 the fire drill is active, it is cancelled
• The Common Alarm Indicator (the ALARM LED) turns on
• The Auxiliary 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 buzzer sounds steadily
