Starting and stopping a walk test
A walk test lets you test individual zones or devices without having to create an
actual alarm condition. You can conduct a walk test in silent or audible mode. In
silent mode, the audible devices (NACs) do not sound.
Zones should be placed in walk test one at a time. This allows the balance of the
system to remain in service. When a device is activated for test, it remains active
throughout the test and does not restore until walk test is ended. When walk test
is ended, all of the tested devices restore.
Note: Walk test does not operate when the panel has an active alarm or
supervisory event.
When you enter walk test mode:
• The Test LED is steady for an audible walk test and flashes for a silent walk
test.
• Walk Test is displayed on the LCD. Walk Test is replaced with the device
activation message during the period the device is activated while in walk test
mode.
• The panel enters a trouble state. There is no fire protection for the zone in
walk test. If an unselected zone or device goes into alarm or trouble, all
programmed outputs operate as programmed.
Zones and devices behave as follows during walk test.
• For alarm events, the appropriate panel and annunciator LEDs and buzzers
turn on. In the audible (NAC) test mode a four-second pulse sounds for NAC
types: continuous nonsilenceable, continuous silenceable, Genesis
nonsilenceable, Genesis with audible silence only, and Genesis with audible
and visible silenceable on the audible devices. A single 3-3-3 cycle sounds for
NAC types: temporal nonsilenceable, temporal silenceable, coder basic,
coder continuous, coder 120spm, and coder temporal on the audible devices.
• For trouble events, the appropriate LEDs and the buzzers turn on. In the
audible (NAC) test mode a two-second pulse sounds on the audible devices.
• For ground fault events, the appropriate LEDs and the buzzers turn on. In the
audible (NAC) test mode, a two-second pulse sounds on the audible devices.
• All device activations are latched until walk test is ended or the panel is reset.
When walk test is ended, it takes approximately eight seconds for the devices
to restore. If the device being tested is in a zone and does not restore, the
zone does not reset.
• If auxiliary power is resettable, the auxiliary power is interrupted while the
zone is reset.
