This extra magnet for a door / window contact sensor allows you to prop a door or window partially open and still keep the sensor in the “closed” position. For example, a window can be kept open and if someone attempts to open it wider, the alarm would still be triggered.
- Compatible with any style of Fortress door / window contact sensor
- Extra magnet can be mounted in a different spot so that a door or window can be propped open
