Indicators, Controls, and Operation
38
• 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
• 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) Circuits Types on page 39).
• If the panel is not already in General Alarm and if the Acknowledge LED is on steady indicating that the Auto
General Alarm timer has been Acknowledged the timer is restarted and the Acknowledge 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 Acknowledge LED if on, turns off
• Alarm inputs are latching: they remain active until system reset.
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.
Initiating (Detection) Circuit Types
Note: If the system is configured for correlations, any second stage / general alarm condition activates all
indicating circuits whether they are correlated or not.
Circuit Type Description
Non-Verified Alarm
This is a "normal" type of alarm which may have pull stations, smoke detectors, or heat detectors attached. Any
activation of these devices will immediately result in an alarm condition in the fire alarm control panel. An alarm
condition causes the associated circuit Status LED and the Common Alarm LED to illuminate red.
Verified Alarm
These alarms are verified by a reset and timing procedure, and may have pull stations, smoke detectors, or heat
detectors attached. Any activation of pull stations or heat detectors will result in an alarm condition in the fire alarm
control panel within four seconds. Smoke detectors will be verified for a real alarm within 60 seconds depending upon
the startup time of the smoke detectors being used. If four seconds is too long a response time for pull stations, then
they should be wired separately on a non-verified alarm circuit. An alarm condition causes the associated circuit Status
LED and the Common Alarm LED to illuminate red. Smoke detectors that incorporate a built-in alarm verification
feature must not be connected to a “Verified Alarm” circuit. For such detectors, use a separately wired non-verified
alarm circuit.
Water-Flow Alarm
An alarm for water-flow sensors. These alarms are identical to normal non-verified alarms except that any indicating
circuits programmed to these circuits (all are by default) are non-silenceable. Also, if water-flow retard operation is
enabled, then these circuits are sampled every one second; if ten samples are active within any 15 second interval, the
water-flow alarm is confirmed and processed. An alarm condition causes the associated circuit Status LED and the
Common Alarm LED to illuminate red. Note: Do not use the retard operation with any external retarding device;
maximum retard may not exceed 120 seconds.
Sprinkler Alarm
An alarm for sprinkler flow sensors. These alarms are identical to normal non-verified alarms unless the water-flow
retard operation is enabled. If water-flow retard operation is enabled, then these circuits are sampled every one
second; if ten samples are active within any 15 second interval, the sprinkler alarm is confirmed and processed. An
alarm condition causes the associated circuit Status LED and the Common Alarm LED to illuminate red.
Note: Do not use the retard operation with any external retarding device; maximum retard may not exceed 120
seconds.
General Alarm
These alarms provide remote general alarm such as for remote key switches. In a two stage system, these inputs
perform exactly the same function as the front panel or remote annunciator general alarm button. In a single stage
system, these inputs act the same as non-verified alarms, but if correlations are enabled, general alarm initiating
circuits are correlated to all indicating circuits.
