The functions of water leak, reed switch and glass break detection will trigger the buzzer to sound. The
default time of the buzzer is 15s, which can be configured through the command. As the buzzer sounds more
power consuming, which affects the service life of the battery, it is recommended that the longest buzzer
time should not exceed 3min.
5.2 Command Rules
5.2.1 IRDisableTime and IRDetectionTime
IRDisableTime and IRDetectionTime are parameters defining PIR/seat occupancy behavior after it detects
motion.
IRDisableTime is the sampling period while IRDetectionTime is detecting period.
By default, IRDisableTime is 30 seconds and IRDetectionTime is 5 minutes.
When PIR/seat occupancy is triggered, PIR/seat occupancy will be turned off for first 70% of IRDisableTime to
save power and then turned on for rest 30% of IRDisableTime.
➢
If living creature is detected during the rest 30% of IRDisableTime, the IR delay time will be extended for
another IRDetectionTime until no infrared signal is detected.
➢
If no living creature is detected during IRDetectionTime, PIR/seat occupancy will report un-occupied along
with other sensor status.
Example1:
While IRDetectionTime is 60 s and IRDisableTime is 30 s, no living creature is detected after triggered.
PIR/seat occupancy will report un-occupied after 60 secs (IRDetectTime).
Example2:
IRDisableTime = 30 s
IRDetectionTime = 60 s
IRDisableTime = 30 s
Turn on for 9 s
(30%)
Turn off for 21 s.
(70%)
Turn off for 21 s.
(70%)
Turn on for 9 s
(30%)
