Indicators, Controls and Operations
• Non-disconnected strobes associated with the input are activated
• Non-disconnected signals associated with the input are activated at the evacuation rate
Pressing the General Alarm button on the panel also initiates a general alarm.
Subsequent alarms when the panel is already in alarm, cause the following:
• The alert buzzer sounds steadily
• If Signals have been silenced, they are resounded, the Signal Silence LED turns OFF,
and the Auto Signal Silence timer, if configured, is restarted. For Canadian installations,
disable Auto Signal Silence.
• Any additional non-disconnected strobes associated with the input are activated
continuously
• Any additional non-disconnected signals associated with the new input are activated at
the evacuation rate
11.4 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, and waterflow alarm. Second stage inputs include alarms
on the general alarm circuits, activation of the General Alarm button, or expiration of the Auto
General Alarm timer. Any of these alarm inputs occurring when the panel is not already in
alarm cause the following:
• The buzzer sounds steadily.
• If fire drill is active, it is cancelled.
• The Common Alarm LED turns ON
• The Common Alarm relay activates if Aux disconnect is not active.
• The Auto Signal Silence timer, if configured, starts. For Canadian installations, disable
Auto Signal Silence.
• The Signal Silence Inhibit timer, if configured, starts.
• All non-disconnected outputs programmed to the input are activated provided that Aux
disconnect is not active.
If the alarm is a Second Stage alarm,
• All non-disconnected strobe circuits are activated continuously, if correlated to an alarm
input.
• All non-disconnected signal circuits are activated at the evacuation rate, if correlated to
an alarm input.
• The General Alarm LED turns ON.
If the alarm is a First Stage alarm,
• Non-disconnected strobe circuits programmed to that circuit are activated continuously.
• Non-disconnected signal circuits programmed to that circuit are activated with the alert
code (see section 11.8 Output Types on page 53).
• The Auto General Alarm timer, if configured, starts.
Subsequent First Stage alarms when the panel is already in alarm, cause the following:
• The buzzer sounds steadily.
• If signals have been silenced as a result of the silence button or the Auto signal silence
timer, signals are resounded as they were before signal silence, the Signal Silence LED
