Simple summary statement:
Your striker plate cannot cover up your alarm sensor, else your alarm will not work.
If you have recessed alarm sensors you will need to:
- determine where they sit on the door frame relative to the center (of the door frame)
- determine the length of the striker plate you are considering, then determine if this will “cover up” these alarm sensors.
Door Devil’s shorter striker plate reduces the chances sensors will be “covered up”.
However, if the sensor is covered up, there are options to remedy the situation:
- you can ask your alarm provider to move the sensor outside the 36″ range of the Door Devil or
- using a metal boring step-down bit to create a hole in the striker plate to allow the sensor’s magnet to connect
