Figure 7.1: Walk test
1. Start at the pattern’s expected boundary and walk across the pattern moving closer to
the detector (refer to the Walk test figure above).
2. 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.
3. 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.
4. When walk testing is completed. the detector returns to normal operation after 90
seconds of inactivity.
