AJAX GlassProtect White | Wireless Glass Break Detector
The AJAX GlassProtect White is a wireless acoustic glass break detector using the DualTone dual-frequency verification algorithm to detect shattering glass up to 9m away across a 180° angle. Runs on a CR123A battery for up to 7 years, communicates over the Jeweller protocol up to 1,000m from the hub, and includes terminals for integrating third-party NC detectors.
Why a dedicated glass break detector? Motion detectors only trigger once someone is already inside the room. GlassProtect catches the break itself, the moment a window is smashed, giving you an earlier warning on ground-floor rooms with large glazing or sliding doors.

Frequently Asked Questions
A contact sensor only triggers when the door or window is opened. GlassProtect listens for the glass being broken itself, so it catches an intruder smashing a window without opening it, and it can cover several windows in a room from one central position instead of needing a sensor on every frame.
The DualTone algorithm requires both the low-frequency impact sound and the high-frequency shatter sound to occur together within 1.5 seconds, which everyday noises rarely produce. Sensitivity is also adjustable across 3 levels, and correct placement during installation reduces false triggers further.
Up to 9 metres across a 180° angle, so one detector mounted centrally can usually cover an entire room’s worth of windows, rather than needing one sensor per window.
Up to 7 years on the single pre-installed CR123A battery. The system sends low-battery notifications well in advance, so there’s no risk of it dying without warning.
GlassProtect works with standard glass types but does not detect breakage through glass covered with shockproof film, sunscreen tint, or similar coatings, since these dampen the acoustic signature it listens for. We’ll check your specific glazing during the site assessment.
