Ajax GlassProtect Jeweller
Summary
The Ajax GlassProtect Jeweller is a professional wireless indoor glass break detector designed to provide comprehensive protection for windows, glass doors, and glazed surfaces. Utilising advanced acoustic sensing technology with an electret microphone, this intelligent detector monitors glass breakage up to 9 metres away with a wide 180° horizontal detection angle, ensuring comprehensive coverage of large glazed areas.
Engineered with sophisticated DualTone two-factor glass break verification algorithms, the GlassProtect Jeweller analyses both low and high frequency components to accurately distinguish genuine glass breakage from false alarm sources. The device includes intelligent filtering to prevent nuisance alarms caused by dogs barking, passing trucks, or other environmental sounds, whilst maintaining reliable detection of actual security threats.
Built on Ajax’s proven Jeweller communication technology, the detector provides secure encrypted wireless communication up to 1,000 metres with comprehensive anti-spoofing protection. The device features an additional NC input for connecting third-party detectors, extending system capabilities, whilst offering exceptional battery autonomy of up to 7 years on a single pre-installed CR123A battery. Configuration and monitoring are simplified through QR code pairing and comprehensive control via Ajax mobile and desktop applications.
