Door/ Window Contact

Made of a transmitter and a magnet, the contact sensor tracks the opening of windows or doors and communicates events to the central panel.

Recessed Door/ Window Contact

A door or window contact that is inlayed into the frame of a door or window to match the surface level. this typically consists of a magnet that is drilled into the side edge of the door or window and an alarm transmitter that is aligned with the magnet and inserted into the door or window frame. this form of door contact provides a clean aesthetic since it cannot be seen when the door or window is closed.
