- power on, several LED flashes for 60 second as self-test
- green LED on = infra-red triggered
- yellow LED on = microwave triggered
- red LED on = both trigger and alarm
- p.count is a coefficient. 1p for indoor, 2p for outdoor adversed situation
- AND/OR is used to choose which tech for alarm. AND (default) = both IR & MW triggered and alarm. OR = either one triggered to alarm
- relay, choose between NO and NC (default)
- Microwave switch = adjust MW sensitivity of distance
- LED ON jumper, disconnect means LED will not flash
