Operating Instructions Walktest
ate outputs and indicate the alarm condition at the FACP. If no additional detector alarms occur
within 83 seconds of the first alarm (23 second retard plus 60 second confirmation), the timer resets
and the panel is ready to verify any new detector alarms which may occur.
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 walk-
test 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 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 and
control modules 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.
4.22 Read Status
Read Status functions do not require a password. The control panel will continue to provide fire
protection while in Read Status mode. This mode can be entered while the control panel is in alarm
or trouble. If a new alarm or trouble occurs during these functions, the Read Status is exited to pre-
vent confusion.
