Indicators, Controls, and Operation
• 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
the Auto Signal Silence timer.
• The Signal Silence Inhibit timer, if configured, starts
• All non-disconnected indicating circuits programmed to the input circuits 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
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 the Auto Signal Silence timer.
• 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
8.6 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, and water-flow 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
the Auto Signal Silence timer.
• The Signal Silence Inhibit timer, if configured, starts
• All Non-disconnected indicating 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
• All non-disconnected signal circuits are activated at the evacuation rate
• 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
