4.1.5 Walktest
The Walktest button, which is located on the FACP membrane switch panel, allows a
panel walktest to be performed. Pressing and holding the Walktest button for a
minimum of two seconds causes the FACP to enter audible walktest. Pressing the
Walktest button and then the Silence button and holding both for a minimum of two
seconds will cause the panel to enter silent walktest. Walktest can be exited by pressing
and holding the Walktest button for a minimum of three seconds or by pressing the
Reset button. Refer to “Walktest” for a complete description of this feature.

4.2 Walktest
Walktest allows the testing of all control panel IDCs (input zones). An audible or silent
walktest may be performed.

It is important to note that while the FACP is in Walktest mode, the control panel is in
an off-normal condition and does not provide fire protection.

Prior to initiating a walktest, check to make certain that all system faults have been
cleared. Upon entering Walktest mode, the following conditions should occur:

smoke detectors will enter their own test mode causing their LEDs to flash

specification document)
• All alarm conditions will be displayed as they occur by blinking zone alarm LED
• All zone troubles will be displayed as they occur by blinking zone trouble LED
• All zone troubles will be displayed as they occur by blinking zone trouble LED
During walktest, the FACP zone LEDs will blink for the first activation on a zone.
Subsequent activations on the same zone will cause the corresponding zone LED to
blink the number of alarms on the zone since the start of the test, followed by a two
second pause and then a repeat of the sequence.
Note that following a zone activation, a 6 second reset for conventional and 60 second
reset for I

detectors is initiated. No new alarms or troubles will be detected during this
reset period.
Disabled zones will not respond during Walktest. A zone may be disabled while in
Walktest mode, should a faulty device be detected. This allows the user to return the
system to Normal mode, enabling all other zones while preventing the faulty zone from
triggering a false alarm.

Audible Walktest
To perform an audible Walktest, press and hold the Walktest button for a minimum of
two seconds. The Trouble and Walktest LEDs will blink at a ¼ second rate.
To perform an audible Walktest, press and hold the Walktest button for a minimum of
two seconds. The Trouble and Walktest LEDs will blink at a ¼ second rate.
While testing input devices, the first initiating device activated on a zone will cause the
NACs to sound for four seconds. Subsequent device activations on the same zone will
cause the NACs to turn on for one second. Any smoke detectors that are activated will
automatically be reset by the panel. Zone faults (open circuits) will cause the NACs to
remain on steadily until the fault is cleared.
During an audible walktest, if a device remains latched in alarm (such as a Pull Station
that is not reset after activation), subsequent testing of devices on the same zone will
not trigger the NACs. Be certain to reset or clear each device after testing.
