Door/Window Magnetic Contact: Magnetic contacts are the most common sensing devices for sensing opening
and closing of doors and windows. They are cheap and reliable.
Such sensors consist of two parts - A contact that is installed on the door / window frame and an Activating magnet that is mounted on the door. The magnetic is held in no-alarm contact position when door / window is kept closed. These are installed on a door or window in such a way that opening the door or window causes the magnet to move away from the contact switch which activates the alarm. They have proved to be a tried and tested method of monitoring any of the operable openings in the houses / apartments. These contacts are available in variety of finishes & materials. Heavy duty versions are also available for heavy doors, shutters and gates. The magnetic switches normally have both 'Normally open' & 'Normally Closed' contacts for easier integration with existing systems.
