Alarm verification is designed for use with smoke
detectors to reduce the number of false fire alarms.
When Verify Time is programmed, the control
panel can double check smoke detector point
activations before generating alarm signals.
DO NOT enable the Cross Point feature
in point indexes designated for Fire points.
Check with your authority having jurisdiction (AHJ)
to determine the maximum verification time
allowed.

Points are programmed individually to activate the
verification feature. See Section 4.1 Point Index. Any
resettable Fire point can activate alarm verification
for the area to which it is assigned. Use separate area
alarm-verification relays.
To enable alarm verification on a point, program
Point Index
Resettable as Yes.
When an Alarm Verification point trips, the control
panel automatically removes power to all Resettable
points connected to the area's Reset Sensors relay.
The sensor reset removes power to the sensors for
the amount of time programmed in Verify Time.
When power is reapplied, a 60-second confirmation
window begins. If the detector is still in alarm, or
trips again during the confirmation window, or if a
different Resettable Verification point in the area
trips, an alarm is generated.
Example: Verify Time is set for 20 seconds. The
alarm verification cycle starts when the detector
trips. No report is generated.
Immediately after the detector trips, the area's sensor
reset relay interrupts power to points connected to it
for the time in Verify Time.
When power is restored to the points, the 60-second
confirmation window is established. If any detector,
reset during the verification time, trips again during
the confirmation window, an alarm is generated. If
no activity occurs during this period, no alarm is
generated and the verification window ends. If a
Verification point trips again after the window ends,
a new verification cycle begins. See Table 23 for an
example of verify time.
