conventional smoke detectors.
4.21 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.
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 (*).
Note that if the system under test includes one or more enabled MMF-302 monitor
modules, the following may apply:
If the MMF-302 monitor module is used for a supervised, 2-wire smoke zone,
alarming any monitor module in the system will result in the activation of pro-
grammed control outputs for an additional eight seconds or less. This is caused by
the temporary removal of 24 VDC resettable power from the MMF-302. The
MMF-302 reports this loss of power as an open condition in addition to the alarm
condition.
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 faulty device, 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.
