Start at the pattern's expected boundary and walk across
the pattern moving closer to the detector (refer to the Walk
test figure above).
While the detector is in the Walk Test Mode, turn ON all
heating and air conditioning sources which would normally
be active during the protection period. Stay away from the
sensor and outside the coverage pattern and watch for
alarms.
The LED flashes at the completion of a 90-sec span of time,
indicating that the Walk Test mode is ending. This occurs
when there is no activity in the sensor's coverage pattern
during the 90-sec interval.
When walk testing is completed. the detector returns to
normal operation after 90 seconds of inactivity.
