Using The Walk Test Command - GE EST iO64 Technical Reference Manual

Chapter 1: System operation

Using the walk test command

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 and devices 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 will not operate with an active alarm or supervisory
event at the panel.
When you enter walk test mode:
• The Test LED flashes for an audible walk test and is steady for a
silent walk test.
• Walk Test is displayed on the LCD display. Walk Test is replaced
with the device activation message during the period the device
is activated while in walk test.
• 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 are turned 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 are
turned 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
are turned 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.
