5.5 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
•
Waterflow alarm
•
Sprinkler alarm
Any of the above alarm inputs activating when the panel is not already in alarm cause the
following:
•
The buzzer sounds steady.
•
Cancels active fire drill.
•
Common Alarm LED turns ON.
•
Common Alarm relay activates if Aux disconnect is not active.
•
The Auto Signal Silence timer activates (if configured).
•
The Signal Silence Inhibit timer activates (if configured).
•
If Aux disconnect is not active, activates all non-disconnected indicating circuits
programmed to the input.
•
Activates non-disconnected strobes associated with the input.
•
Activates non-disconnected signals associated with the input at the evacuation rate.
Subsequent alarms when the panel is already in alarm, cause the following:
•
The alert buzzer sounds steady.
•
Resounds silenced signals, turns off the Signal Silence LED, and restarts the Auto
Signal Silence timer (if configured).
•
Activates continuously any additional non-disconnected strobes associated with the
input.
•
Activates at the evacuation rate any additional non-disconnected signals associated
with the new input.
