ABORT AUDIBLE AND DELAY ON REACTIVATION
Whenever a Walk Test
group is aborted, either manually or automatically, the control list sounds the abort signal
“TESTING COMPLETED” (or 0-0-0) to indicate that the group is going back into service. If a control point in the list
is already active, possibly because another alarm has come in, the “TESTING COMPLETED” message will play
before the alarm message. The group is put back into normal operating service 60 seconds after the abort signal is
heard (if there are signals in the control list). This delay protects against an unwanted alarm should an auto abort
occur while a device is being tested.
ACTIVE/NOT ACTIVE
The <F1> key on the interface panel is used to toggle ON and OFF a given Walk Test
group. All groups are initially
inactive at system start-up. Any number of groups can be enabled at any one time. When a Walk Test
group is
enabled, its associated trouble pseudo point is turned ON and must be acknowledged. If multiple Walk Test
groups
are required, press the trouble acknowledge key after all Walk Test
groups are selected.
AUDIO Walk Test
When an Audio Walk Test
is performed, the zone number is announced over the activated speaker circuits instead
of a zone code.
AUDIO ZONE CODING
Audio zone coding uses spoken zone numbers rather than coded zone numbers. To report a zone, the system
announces “TESTING ZONE”, followed by the associated point number of the zone being tested. For example,
during a test of Zone 97, the system would announce “TESTING ZONE NINE SEVEN.” Zone Coding must be
selected with the Walk Test
Menu <F3> key for this test to work properly.
AUDIO ZONE/SIGNAL TROUBLE
When an open circuit trouble is detected on a zone, the system announces “TESTING ZONE”, followed by the
associated point number of the zone being tested, and the word “TROUBLE”. For example, if an open circuit trouble
was detected during a test of Zone 97, the system would announce “TESTING ZONE NINE SEVEN, TROUBLE”.
AUTO ABORT ON ALARM
When an alarm is detected from a zone that is not in the active Walk Test
group, all normal control functions take
place and the active Walk Test
group is aborted. When a non-audio Walk Test
is aborted, the system sounds a
zero code three times. If an audio Walk Test
is aborted, the system announces “TESTING COMPLETED” over the
speaker circuits for the Walk Test
group under test.
AUTO ABORT ON TIME-OUT
If there has been no activity within an active Walk Test
group for 8 hours, the system aborts the Walk Test
automatically.
CONTROL LIST
A Control List is a point list that contains those control points (signals and/or relays) that are to be activated by a
Walk Test
group. By default, this list is initially filled by the system for Group 0, and includes all signal, visual, or
coded control points.
