9.7.2
Non-Verified Alarm
A Non-Verified alarm is a “normal” type of alarm that can have pull stations, smoke detectors,
or heat detectors attached to it. Activation of any 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.
9.7.3
Water Flow Alarm (Water flow Sensors)
Water Flow 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, 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.
9.7.4
Non-Latching Supervisory (For Supervisory Circuits)
Activation on these circuits will cause the Circuit Status LED and the amber Common
Supervisory LED to illuminate. The buzzer will sound at fast rate. If the circuit activation is
removed, the Supervisory condition will clear (as long as there are no other Supervisory
conditions in the system) and the Circuit Status LED will turn off.

Note:
Some troubles are latching once they are detected they remain active until
system reset. In this case the common trouble indicator will also remain active
until system reset. The common trouble is not bypassed by the auxiliary
disconnect function.
Note:
Do not use Retard Operation with any external retarding device; maximum retard
may not exceed 120 seconds.
