Red!LED!Indicator!
The red LED on the front of the PIR serves three functions:
1) Indicates the battery voltage on power-up
2) Indicates the Operating Mode and Channel setting
3) Helps sensor alignment and sensitivity testing during the first 5 minutes
Power-up!Sequence!
When the sensor is first turned on, the LED will flash up to 5 times. There is
then an 8 second delay before the sensor will flash four times and start
operating.
The number of flashes during the initial power-up phase provides a quick
indication of the remaining battery level. This battery indicator has been
calibrated to be most useful when the sensor is powered by six Alkaline
batteries.
The battery life thresholds are as follows:
Number of
flashes

More than 80%
4
60%-80%
3
40%-60%
