Before beginning, it is important to select a suitable position for your Recessed Door Sensor. For optimal performance, your sensor should be:
- Either installed at the top of a door or the side of a door.
- Positioned away from metal that could interfere with its magnetic functionality or wireless functions. This includes your door's plate, handle or lock mechanism.
- Installed in a suitable location to ensure a clear (between 1mm and 5mm) separation when the door is closed.
- Positioned exactly above or beside the position in which Magnetic Sensor will be inlaid. With the main sensor powered and activated, it is now time to inlay it within your selected door frame. Step 1 - Drill for Sensor's main body. Prepare the space for Main Sensor by drilling a hole into your doorframe using a 19mm/0.75 inch wide drill bit (you can use a slightly larger drill bit if needed). The hole should be 70mm/2/75 inch deep. Step 2 - Drill for magnet piece. Drill a corresponding hole in your door. The hole should be 15mm deep. As stated, the position of this hole should align exactly with the hole you just created in the doorframe. Again, use a 19mm wide drill bit. With your door and door frame prepared and the drill holes created, it's now time to mount both parts of your Recessed Door Sensor. Step 3 Place a small amount of white glue (PVA) inside the hole you created for Magnetic Sensor. Then, place the sensor over and into the hole. Next, insert it by tapping gently on it with a rubber hammer. Step 4 The gap between the two parts of your sensor must be no less than 1mm and no more than 5mm. If your gap is different, re-affix Main Sensor by altering its hole.
