Operation
When a printer is installed, the
printer prints a message similar to the
following:
WLK [event type] IN/OUT device ad-
dress time/date device type, custom
message, trouble type (if applicable)
The LCD displays the following for
eight seconds:
1-001 [custom msg] WLK IN/OUT
[event type] device type
If the ALD device has an LED, it turns
on for 30 seconds to provide additional
feedback to the technician.
If the MXL detects multiple events,
they are automatically spaced 8-10
seconds apart to allow for separation
of the coding. Up to five simultaneous
events may be held in order for pro-
cessing.
When five minutes remain, the
System begins the Walktest ending
sequence.
NOTE: If an alarm or supervisory is
reported from a device that is NOT in
Walktest, the Walktest is suspended
immediately. No further Walktest
events are annunciated or coded. The
Walktest remains running in the
background of the MXL until it times
out or is canceled.
WARNING: When performing a partial
system Walktest, DO NOT TEST any
devices that are not in the Walktest,
as this will cause an alarm in the
system.
Walktest Ending Sequence
When 5 minutes remain in Walktest,
all silenceable and non-silenceable
audibles that are not already active or
disarmed cycle on-off five times (1
second on) to indicate that the Walktest
will time out in 5 minutes. This occurs
in both the silent and audible modes.
When 1 minute remains, event
coding and the processing of devices
to the LCD are suspended. If a device
is alarmed, it is cycled silently through
the resetting sequence.
When 45 seconds remain, all
silenceable and non-silenceable
audibles that are not already active or
disarmed cycle on-off until Walktest
times out. Do NOT continue to
walktest devices. This 45 second
period of no new Walktest events
ensures that all devices are reset when
the Walktest timer expires and the
System returns to normal operation.
Alarming a device during this period
might result in the reporting of errone-
ous events when the System returns
to normal operation.
