4.17.5 Alarm Verification (None or One Minute)
If alarm verification is selected, a smoke detector activation will cause the FACP to reset the
detector by removing power for 6 seconds. Power is reapplied and a 17 second retard period begins
which allows all detectors to stabilize. If no other detectors alarm, there will be no alarm indication
at the FACP during the 23 second Reset/Retard period. A Confirmation period of 60 seconds
follows, during which a subsequent alarm from the same detector will cause the panel to
immediately activate the appropriate outputs and indicate the alarm condition at the FACP. If a
different detector zone alarms any time during the first detector's Retard & Confirmation period,
the panel will immediately activate all appropriate outputs and indicate the alarm condition at the
FACP. If no additional detector alarms occur within 83 seconds of the first alarm (23 second Reset/
Retard plus 60 second Confirmation), the timer resets and the panel is ready to verify any new
detector alarms which may occur.
Note: Alarm Verification is available only for smoke detectors.
4.18 Walktest
Walktest is a feature which allows one person to test the fire alarm system. An audible walktest
will momentarily sound the Notification Appliance Circuits in the building and store the walktest
information in a file at the panel. A silent walktest will not sound the NACs but will store the
walktest information in a file which can be viewed at the panel. Disabled NAC devices will not
activate during walktest. In addition, I
3
smoke detectors will enter their own test mode causing
their LEDs to flash twice every five seconds (refer to I
3
specification document).
Alarm/Shorted Condition
When in audible Walktest, the panel responds to each new alarm and activates its programmed
control outputs for four seconds, if those outputs have been programmed for silenceable activation.
It also stores each alarm in the walktest history file which can be sent to an optional printer. The
stored display will be the same as if the device actually activated except the colon (
:
) in the time
stamp is replaced with an asterisk (
*
).
Open Condition
Addressable devices as well as all main circuit board NACs are monitored for fault conditions
during Walktest mode. When a new trouble condition occurs, the FACP will activate all NACs
programmed for Walktest, then shut them off after eight seconds.
While in Walktest, the trouble relay is activated and the system Trouble LED flashes (as in all of
the Program and status change operations). The alarm relay is not activated.
