False alarms on a Honeywell Motion Detector
There are several things that can cause a false alarm on a 5800 PIR motion detector including, heating/AC vents, pets, stoves, and windows. A good way to test the sensor, is to cover it with a piece of paper, or a towel, or something similar. Continue to arm the alarm system on Away with the motion sensor covered, and if the false alarms continue, that sensor is most likely broken and will need replacement. If this is the case, contact our Technical Support department for assistance.
