Alarm Contact switches are magnetic switches used to protect doors and windows for the most part. Doors are the most common place of entry and should be protected by your alarm system. The HomeSecurityStore.com always recommends contacting every perimeter door in your home or business.
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. So if you’re concerned about the aesthetic, go with recessed; if you’re looking for a more cost-effective solution, go with surface contacts.
