For NAC short circuit testing, place a short across the NAC output terminals and
verify that the system Trouble LED and the circuit’s trouble (TBL) LED turn on.
Caution: Do not place the short across the 24VAC IN terminals.
For AUX power short circuit testing, place a short across the AUX power output’s
plus (+) and minus (−) terminals and verify that the system Trouble LED turns on.
For communications testing, place a short across C+ and C− and verify that the
system Trouble LED and Annun Trouble LED turn on.
Performing a walk test
A walk test lets you test initiating device circuits (IDCs) without having to create
an actual alarm condition. IDCs should be placed in walk test one at a time. This
allows the rest of the system to remain in service. Walk test will not operate with
an active alarm or supervisory event at the panel.
You can conduct a walk test in silent or audible mode. In silent mode, the audible
devices (NACs) do not sound. In audible mode, the NACs sound for a number of
times equal to the zone number. Example: three times for IDC 3.
WARNING: If you cancel a walk test with a device in the active state, the control
panel will activate the programmed responses for that device. Do not cancel a
walk test when the Trouble LED for the IDC under test is flashing rapidly.
In a walk test, the panel responds to the first signal it receives and ignores all
others on that IDC until it clears that signal or the panel is reset. The input must
be restored to the normal state before the next input is tested. When the input is
restored, the panel automatically resets the circuit being tested. The automatic
reset takes eight seconds. After the circuit is reset, the next device can be tested.
The panel terminates the walk test if:
• A zone other than the zone being tested is activated
• There are 30 minutes of inactivity on the zone being tested
• The panel is reset
• The Walk Test button is pressed a third time
When you press Walk Test:
• The Walk Test LED turns on or flashes depending if you selected a silent or
audible walk test, respectively
• The panel enters the trouble state
