The ADT Wireless Door Window Sensor Magnet is a magnet for the wireless door sensor or window sensor. If you need to replace a magnet on your ADT Wireless Door or Window Sensor this is the part you need. It will work with almost any door or window sensor.
If you are using a wireless transmitter with your magnet, you need to make sure you install the magnet no further than ½” from the senor when the door/window is closed. If the magnet is further than ½” from the transmitter, it will falsely state that the door/window is open. Proper alignment between the magnet and the sensor is essential to proper function of the sensor. Make sure the magnet is between the two-line marks on the side of the wireless sensor. That area is typically marked by a sticker. Improper installation of the magnet will cause the window sensor to malfunction and provide false readings.
If you wanted to keep your window open while it is armed you could install a second magnet 3-6 inches in. So that it would be lined up with the sensor even while the window is open. That way you could arm your system without bypassing a window sensor.
The ADT Wireless Door Window Sensor Magnet is designed for the wireless window and door sensors, however you can use them as replacement magnets for other door and window sensors as well. The magnet is 1.5” long, 1/2” wide and 1/2” deep and is slightly larger than the typical magnet found with a wired door and window contact.
This magnet comes in a bag with a plastic spacer, 2 screws, and a piece of 3M adhesive tape. You can either use the included tape or screws to mount your magnet. You could also use glue or silicone but those do not come with the magnet.
