When configured as normal, the output circuit is ON continuously when activated and does not
use any sync protocol. When configured as non-silenceable strobes, the strobes cannot be
silenced, but the horn can be silenced by pressing the 'signal silence' button.
If the strobe is configured as silenceable strobe both the horn and the strobe are silenced
(stopped) by pressing the 'signal silence' button.

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.

Two-Stage Operation
In a two stage system, alarm inputs are either first stage (alert) inputs or second stage
(general alarm) inputs. First stage inputs include inputs from the following types of circuits:
•
Non-verified alarm
