4.22: 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 monitor modules, the following may apply:
If the monitor module is used for a supervised, 2-wire smoke zone, alarming any monitor module in the system will result in the activation of programmed control outputs for an additional eight seconds or less. This is caused by the temporary removal of 24 VDC resettable power from the monitor module. The monitor module 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 acti- vate 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 opera- tions). The alarm relay is not activated.
