The LED on your motion sensor indicates when it senses motion. If the LED on your motion sensor does not light up, it doesn’t mean the sensor is not working. Motion sensors have a built in sleep mode that will save battery life if there is a lot of movement in your home. If the LED of your sensor did not light up, it could be in sleep mode.
If you’re concerned that your motion sensor isn’t working correctly, you can always test your security system. You will need to arm in Away mode to engage the motion sensor. Some systems require you to open an entry/exit door before it will Arm to Away. For more info, please check out our guide on testing your Guardian system here.
During your test, wait about four to five minutes before attempting to trigger your motion sensor.
