Walktest Operating Instructions
4.21.4 Waterflow Retard Timer
If selected, this option will delay the activation of a waterflow type alarm for a programmable time
duration from 1 to 90 seconds. This delay is in addition to any time delay inherent in the waterflow
device. This feature requires the approval of the local Authority Having Jurisdiction.
4.21.5 Alarm Verification
If alarm verification is selected, an addressable smoke detector's alarm is ignored for a Retard time
of 13 seconds and the detector’s alarm condition is automatically reset. There will be no alarm indi-
cation at the FACP during the 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 alarms any
time during the first detector's verification period, the panel will immediately activate all appropri-
ate outputs and indicate the alarm condition at the FACP. If no additional detector alarms occur
within 73 seconds of the first alarm (13 second Retard plus 60 second Confirmation), the timer
resets and the panel is ready to verify any new detector alarms which may occur.
4.22 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 infor-
mation 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.
Alarm/Shorted Condition
When in audible Walktest, the panel responds to each new alarm and activates its programmed con-
trol 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 are monitored for fault conditions during Walktest mode. When a new trouble
condition occurs, the FACP will activate all NACs and control modules programmed for Walktest
and mapped to the faulted device, then shut them off after eight seconds.
NOTE: Alarm Verification is available only for addressable smoke detectors, not conventional
smoke detectors.
