• 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.
5.6 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
• Verified alarm
• Sprinkler alarm
• Water-flow alarm
Second stage inputs include the following:
• Alarms on the general alarm inputs.
• Activation of the General Alarm button.
• Expiration of the Auto General Alarm timer.
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.
If the alarm is a Second Stage alarm, the following occurs:
• Activates non-disconnected strobes associated with the input.
• Activates non-disconnected signals associated with the input at the evacuation rate.
• General Alarm LED illuminates steady.
If the alarm is a First Stage alarm, the following occurs:
• Activates continuously non-disconnected strobe circuits programmed to that circuit.
• Activates with the alert code non-disconnected signal circuits programmed to that circuit.
• Activates the Auto General Alarm timer (if configured).
• Acknowledge LED flashes.
