Intruders can break silence, not security
Forget about the typical problem of glass break detectors — false alarms caused by barking dogs, traffic, water splashing, and extraneous noise. GlassProtect Jeweller has a unique DualTone digital algorithm designed to minimize false alarms. The detectorʼs microphone responds only to vibrations characteristic of the glass breaking sound. You can adjust one of three sensitivity levels and run the test to check if everything works properly.

Enhanced glass break detection
GlassProtect Jeweller uses a sensitive electret microphone and the DualTone digital algorithm to detect the sound of glass breaking. To register a glass break and report an alarm, the device must detect a dull (low-frequency) sound of an impact and a ringing (high-frequency) sound of glass breaking in 1.5 seconds. This two-stage glass break detection algorithm decreases the risk of false alarms. Three sensitivity levels can be configured in the Ajax app, making the detector suitable for any object.

Easy integration with third-party detectors
GlassProtect Jeweller has terminals for connecting a third-party wired NC detector. This allows the installer to enhance system reliability with any NC detector, whether newly installed or already in place, such as motion, opening, or vibration detectors. For example, GlassProtect Jeweller enables you to integrate an existing third-party² opening detector into the system.

Wire-free flexibility and reliable performance
Baseline devices operate without any wires, offering maximum flexibility during installation. The pre-installed CR123A battery from proven manufacturers ensures a hassle-free setup, requiring no additional steps to start operating the devices. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the battery characteristics. The battery can be easily replaced after approximately five years of autonomous operation. Its status is always accessible in the Ajax app. Users and security companies receive low battery level notifications months in advance, allowing for timely replacement without rushing.

Effortless installation and setup
GlassProtect Jeweller is ready to operate straight out of the box. Using the SmartBracket panel, an installer can effortlessly mount the device on the wall, eliminating the need to disassemble the enclosure. Ajax apps help quickly make the device a part of the ecosystem: simply pair the device with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.

²GlassProtect Jeweller can’t power a third-party detector. The power supply for this detector should be connected separately.
