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. Refer to 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, Fire Point, Alarm Verify, and 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.
