11.6 Circuit Types
The term circuits refers to an actual electrical interface, either initiating (detection) or NAC
(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.

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 Manual Stations, smoke detectors attached. Any activation of
Manual Stations 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. Verified Alarm is not permitted
for heat detectors, 4-wire smoke detectors and smoke detectors with
built-in alarm verification. Refer to Appendix F: Alarm Verification
Timing on page 98 for details.
Water-Flow Alarm An alarm for water-flow sensors. These alarms are identical to normal
non-verified alarms except that any NAC 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.
