Door & WIndow Sensor – Causing False Alarms
If your door/window sensor is experiencing false alarms, it’s usually because the magnet or the sensor has fallen off the doorframe while your system was armed. If you’re experiencing difficulties reattaching your sensor to the doorframe, contact Customer Care for assistance. Also note that storms or strong wind can sometimes push doors slightly open in the doorframe, which can create a gap between the sensor and the magnet. A space that is more than half an inch will trigger a false alarm.
