A door and window contact requires (1) CR123 3 volt battery (in some systems, the door and window contact will be a very slim device and will contain a single, CR2032 battery). This battery can often be purchased at your local hardware, mass retailer or battery store.

A door or window sensor is typically a two-piece magnetic contact sensor. When the system is armed and a door or window is opened, the two magnetic sensors are separated from each other, thereby tripping the alarm. 

If a protected door or window with a sensor is open, you will not be able to arm the system until the door or window is closed or the zone is bypassed. If your door or window sensor is causing false alarms, the door or window may not be securely closed or the sensor may be damaged. Swelling or contracting of the door or window due to changing weather may also result in false alarms. 

If you are having problems with your door or window sensors you may try troubleshooting the problem from our Sensor Troubleshooting page to determine if a service visit is necessary.

To find out if you can move a sensor for the system installed in your location, refer to your security system user’s manual.
