## Summary description

Ajax GlassProtect Wireless Black is a wireless glass break detector designed to detect breaking or striking of glass. The compact sensor monitors acoustic and shock events near windows or glass doors and integrates with Ajax security systems. Suitable for homes and offices, it provides discrete protection against glass intrusion and notifies the user via the connected alarm system.

## Long description

Ajax GlassProtect Wireless Black is a compact wireless glass break detector that monitors acoustic and shock events near windows and glass doors. The device combines dual-frequency acoustic detection with an electret microphone and an external contact input to reliably detect glass breakage while remaining small enough for discreet mounting. It communicates with Ajax Hub via the Jeweller protocol and supports integration with third-party systems through uartBridge and ocBridge Plus.
Advantages
The detector provides two-factor detection (low and high acoustic frequencies) to reduce false alarms and offers up to 9 m detection range for broken glass. It supports wireless operation up to 1,000 m in open space from Ajax Hub, features tamper protection and authentication against interference, and can operate for up to 7 years on a single CR123A battery with adaptive power management. Installation is simplified with SmartBracket mounts and one-click connection to the Hub, and sensitivity is adjustable across three levels.
Suitable for
Protection of home windows and balcony doors
Security for office glazing and storefront windows
Integration into Ajax systems and third-party alarm panels via bridges
Locations requiring discreet, small-form sensors

How to use
Install the GlassProtect detector on or near the protected glass surface using the SmartBracket mounting plate; there is no need to disassemble the body during installation. Connect the device to Ajax Hub with a single click in the mobile app and test the connection and detection area remotely. Adjust sensitivity (low, medium, high) and set the ping interval (12–300 seconds) from the Hub to balance responsiveness and battery life. Optionally connect an external opening detector to the external contact input for combined door/window monitoring.
Usage recommendations
Place the detector within the specified detection range and avoid obstructing the microphone. For reliable coverage, mount the device on the glazing frame or nearby solid surface aimed toward the glass. Use the middle sensitivity level as a starting point and adjust if needed to reduce false alarms caused by environmental noise. When integrating with third-party systems, use uartBridge or ocBridge Plus according to the manufacturer’s integration guide.
