Wireless glass break detector with a microphone
Standards and certifications
GlassProtect Jeweller · GP.Y.J. Manufacturer-listed marks; regional and installation conditions apply.
Listen for a different way in.
GlassProtect Jeweller uses a microphone to recognise the sound pattern of breaking glass. It adds protection where an intruder could break a pane without opening its frame. Sound analysis helps distinguish a break from everyday noise, while positioning and testing establish coverage for the windows in the room.

Recognise the sound of breaking glass.
Two sounds. One confirmed event.
The electret microphone and DualTone analysis look for a low-frequency impact followed by high-frequency shattering within 1.5 seconds. Three sensitivity settings help adapt detection to the room.
Detection reaches up to 9 m across a 180° angle. Placement, obstructions and the acoustic conditions affect the actual result.
Include an existing wired detector.
External NC input
A supported third-party detector with a normally closed contact can be connected to GlassProtect’s terminals. This can bring an existing opening, vibration or motion contact into the Ajax system.
GlassProtect does not power the external device. An installer checks its power supply, contact type and wiring.
Power for everyday protection.
Replaceable battery power
The preinstalled CR123A battery makes the detector independent of a supply cable. Battery state and low-power notifications are available in the Ajax app.
Battery life depends on settings, use, temperature and signal conditions. Respond to the app’s low-battery notification.
A secure link to your system.
Jeweller communication
Jeweller carries alarms, status and commands between this detector and a compatible hub or range extender. The two-way link uses encryption and device authentication.
The stated range is up to 1,000 m in open space. Walls, metal and the actual installation reduce usable coverage.
Reach the areas your system needs.
Plan around walls and distance
Test the signal where the detector will be installed. If coverage is insufficient, select a compatible range extender; an Ethernet-equipped model provides another route back to the hub.
Range extenders are optional equipment. Check supported models and quantities against the exact hub before planning coverage.
Know that protection is working.
Device state in the app
The detector reports its condition to the hub. Communication, power and tamper information help identify a device that needs attention. Clear device and room names make an alert easier to act on.
Professional alarm monitoring is a separate service. Notification and connection-loss timing depend on system settings and connectivity.
Protection that also watches itself.
Removal alerts
The tamper reports attempts to remove the detector from its mounting panel. Secure the mounting arrangement and check that the event reaches the intended users.
Authenticated communication
The hub checks the detector’s identity during communication. Encryption protects the exchanged data, while authentication helps reject a device attempting to impersonate it.
Installed for your actual space.
Connect
Scan the device QR code to add it to a compatible hub. Assign a clear name and the room or area where it will operate.
