Indicators, Controls, and Operation
• Non-disconnected signal circuits programmed to that circuit are activated with the alert
code (for more information see Indicating (Signal) Circuit Types on page 58)
• 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
turns off, and the Auto Signal Silence timer, if configured, is restarted. For Canadian
installations, disable the Auto Signal Silence timer.
• If the panel is not already in General Alarm, additional non-disconnected signals
programmed to the new input are activated with the Alert Code (for more information
see Indicating (Signal) Circuit Types on page 58)
• If the panel is not already in General Alarm and if the Automatic Alarm Signal Cancel
LED is on steady indicating that the Auto General Alarm timer has been acknowledged,
then the timer is restarted and the Automatic Alarm Signal Cancel LED is extinguished
A second stage alarm (general alarm) when the panel is already in alarm causes the following:
• The buzzer sounds steadily
• All non-disconnected signals are activated at the evacuation rate
• If the Signal Silence LED is on, it turns off and the Auto Signal Silence timer, if
configured, is restarted
• The Automatic Alarm Signal Cancel LED if on, turns off
• Alarm inputs are latching: they remain active until system reset.
8.7 Circuit Types
The term circuits refers to an actual electrical interface, either initiating (detection) or
indicating (signal). The term zone is a logical concept for a fire alarm protected area, and will
consist of at least one circuit. Often the terms zone and circuit are used interchangeably, but in
this manual the term circuit is used.
Note: If the system is configured for correlations, any second stage / general alarm
condition activates all indicating circuits whether they are correlated or not.
