Ajax DoorProtect Door Sensor — Black

Ajax DoorProtect Jeweller tells your alarm the moment a door, window or skylight is opened. It is the workhorse perimeter detector in an Ajax system, fitted to entry doors, sliding doors and openable windows in homes, offices and shops. This is the black version.

A sealed reed switch rated for more than two million openings sits in a plastic capsule, and two magnet sizes are supplied so the detector fits narrow window frames as well as standard doors. It runs for up to seven years on the pre-installed CR123A battery and reports to the hub over the encrypted two-way Jeweller radio protocol, so a jammed or removed detector shows up as a fault rather than silence.
