Magnetic Door Contact

Magnetic Door contacts are designed to be recessed in the door, and provide protection from burglars.

Recessed has the magnet placed in a 3/8″ hole drilled into the edge of the door, and the switch in another hole drilled into the door casing, wiring concealed in the wall.

Recessed Magnetic Door Sensors are typically used on closed-circuit alarm systems. These devices work with magnets. These magnet sensors are mounted inside the door and inside the frame. When the door is closed and the magnets are lined up, the switch is closed. These devices are made to be ascetically pleasing since they cannot be seen and also to be less prone to tampering. Below are the pros and the cons of using this type of door contact.

Pros of Recessed Magnetic Door Contacts

Less Risk of Tampering: since these devices are installed inside the door and frame they are far less likely to be tampered with since they cannot be seen when the door is closed. Invisible when the door is closed: This makes for the devices to be more aesthetically pleasing than the surface-mounted door contacts. These are the standard type of contacts used in residential settings for this reason.

Cons of Recessed magnetic Door Contacts

Harder to Install than surface contacts: Since they have to be installed on the door and the frame, they are more difficult to install than the surface contacts which stick right onto the outside.

Alternatives

The other alternative to using recessed door contacts is to use surface door contacts. These are typically a little cheaper and easier to install than the recessed door contacts, but they are visible and more prone to tampering.
