We are having problems with two contact sensors, one on an exterior door and one on the door leading to our garage. A factory reset seems to have fixed the problems with the one on the door leading to the garage, but problems with the other one have continued despite a factory reset.
Both of these sensors have triggered false alarms. Two of the false alarms required me to return home from driving to work. The most recent false alarm happened when we were sitting inside with our alarm armed on home, and out of nowhere the contact sensor on the exterior door triggered the alarm. We were sitting right by the door, and nothing moved to trigger the alarm.
This sensor also often shows open and we have to bypass it to arm our system.
Has anyone else had experience with contact sensors failing/acting like this? We purchased and installed our alarm system in August, and we are incredibly frustrated because of these contact sensor performance issues. This kind of experience makes me want to research other alarm alternatives. Any help or advice is appreciated.
