GlassProtect Jeweller
Wireless glass break detector with a microphone
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.
GlassProtect Jeweller doesn’t respond to the breaking of glass covered with shockproof, sunscreen, decorative, or any other film. To detect such glass breaking, we recommend using DoorProtect Plus Fibra, DoorProtect S Plus Jeweller, or DoorProtect G3 Fibra detectors with shock and tilt sensors.
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.

Jeweller
Unique wireless technology
An Ajax system uses two-way secure radio communication based on the Jeweller proprietary protocol. It provides block encryption and device authentication at each communication session with the hub to prevent sabotage, spoofing, or data theft.
Up to 1,000 m (3,250 ft) of radio communication with a hub or a range extender1
Encrypted two-way radio communication
Notifications about jamming and communication loss
Scaled and comprehensive
ReX 2 Jeweller boosts the radio range of all Ajax devices via Jeweller and ensures stable communication even through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering underground parking, basement, or metal hangar.

Ethernet as an alternative communication channel
System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, such as a tamper state, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs, security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.
Automatic device self-diagnosis with status report
Regular polling to display the current device state in apps
Instant maintenance notifications
Sabotage resistance
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.

Wireless glass break detector for alarm system Ajax GlassProtect
The security system is designed to protect the territory from fires, leaks and intrusions. Appropriate detectors for each type of threat help prevent property damage and secure the premises. The glass breakage sensor is one such device. Glass breakage sensors are used indoors and signal burglary after the corresponding sound is recorded. Glass break detectors are installed in private premises, shops, offices, etc. Before installing a glass break detector, users should familiarize themselves with the types and features of the devices.Classification of glass break sensors
According to the principle of work:- Piezoelectric glass break sensors — react to mechanical impact. Annunciators activate oscillations in the glass sheet after impact. There are two types of piezoelectric sensors.
- Electrocontact glass break sensors — determine the integrity of the glass by mechanical control. An electrocontact type sensor is presented in the form of a thin wire in a fragile sheath or in the form of a wide strip of metal foil, which is coated with a lacquer dielectric. An electric current is passed through the conductor. When the glass surface is broken, the conductive element breaks. This technology is rarely used due to a number of disadvantages:
- Labour-intensive installation of fragile elements and the impossibility of their connection in the event of an accidental break, even by soldering.
- Not an aesthetic appearance and excessive attraction of the attention of intruders. Glass can be cut without touching the wires.
- Acoustic glass break detectors — react to the sound characteristic of broken glass. Sound sensors activate an alarm if they detect acoustic waves in the spectrum characteristic of broken glass.
- High speed of response to the pathogen and recognition accuracy.
- Wide range of settings and high sensitivity.
- Convenient installation and connection. Indoor installation on walls or ceiling.
Features of acoustic glass break sensors
Device activation algorithm:- The sound sensor microphone receives acoustic vibrations and converts them into an electrical signal.
- The sound sensor actuators can generate several signal types depending on the model.
- Depending on the model, the sound sensor actuators can generate several signal types
Device selection and installation options
Users need to pay attention to the monitored glass sheet type, size, and thickness when choosing a sound-type glass break sensor. Most of the models are universal devices, in memory of which there is information about the most common types of glass in construction. The acoustic sensor can work with 2.5-8 mm glasses.Please note that separate settings or specific sensor models are required for reinforced or laminated glass.Power type. There are glass break sensors with an autonomous power source and connection to the alarm system loops. Such devices operate from 8-30 V. Wired break sensors must be installed in the interior at the design stage to install the power cable. Effective sensing distance. Users should not place the device at the maximum distance indicated by the manufacturer in the instructions since, in this case, the sensor sensitivity works at its full, and more energy is consumed. Glass break sensors are recommended to be mounted on walls or other load-bearing structures that are not subject to vibration at the height of up to 2 m. Such an arrangement of the device will prevent obstruction of the signal of the glass break detector by third-party objects and its unauthorized dismantling. When installing the device, users need to consider the presence of protective films, curtains, blinds and other elements on the glass. They can distort or make the breaking sound weak. An essential function of the glass break sensor is anti-masking, preventing sensitive sensors from being blocked.
