Spec Data Sheet Button

Ajax GlassProtect White is a miniature wireless indoor glass break detector that recognizes the sound of glass breaking from a distance of up to 9 meters. At the same time, passing cars or barking dogs do not cause false alarms.

The GlassProtect can operate up to 7 years from a pre-installed battery and has a socket for connecting a third-party wired detector.

GlassProtect operates within the Ajax system, connected to the hub via the protected Jeweller protocol.

The detector is compatible only with Ajax Hub, Ajax Hub Plus, Ajax ReX, Ajax ocBridge Plus and Ajax uartBridge.

Product Code: 5288.05.WH1

Please Note: GlassProtect detector does not react to the breaking of the film-covered glass: shockproof, sunscreen, decorative, or any other type of film. To detect the breaking of such kind of glass, we recommend using the DoorProtect Plus wireless opening detector with shock and tilt sensors.
