Door and Window alarm contacts are essential to any home or business security system. The technology is very simple. Each contact consists of a sensor, which is attached to the frame of the door or window, and a magnet, which is placed on the door or window itself. The magnet acting on the sensor creates a circuit, and when the sensor is separated from the magnet, a signal is sent to the alarm control panel, signifying an entry breach.

There are two primary types of door and window contacts: Recessed alarm contacts and surface mount alarm contacts. With recessed alarm contacts, the magnet and sensor are installed inside the frame and the door or window.

Alarm wire is necessary for all hardwired alarm contacts. 22 Gauge Station Security Wire is suitable for most security systems and other low voltage electrical hookup security products.
