PRODUCT DETAILS
The Ajax CombiProtect U Jeweller is a reliable 2-in-1 wireless motion and glass break detector designed to provide fast, accurate intrusion detection while minimising false alarms. Combining a PIR motion sensor with an advanced acoustic glass break sensor, it delivers comprehensive room protection from a single compact device.
Powered by Ajax’s new U-Jeweller wireless protocol, the CombiProtect U offers extended communication range, enhanced resistance to interference, and long-lasting energy efficiency—ideal for both residential and commercial installations. It accurately detects human movement up to 12 metres, while recognising the distinct sound patterns of breaking glass up to 9 metres, ensuring complete perimeter protection.
Features:
- Dual detection technology – PIR motion + acoustic glass break sensor
- U-Jeweller wireless communication – long-range, secure transmission (up to 1,700 m line-of-sight)
- 12 m motion detection with a wide 88.5° field of view
- Glass break detection up to 9 m – monitors multiple windows in a room
- Pet immunity up to 20 kg – avoids false alarms caused by small animals
- Advanced sound analysis – detects both impact and shattering frequencies
- Automatic temperature compensation for consistent performance
- Tamper protection – alerts if the device is opened or removed
- Up to 5 years battery life for low-maintenance operation
- Easy installation with SmartBracket and quick QR-code pairing
- Compatible with Ajax hubs and range extenders using the U-Jeweller protocol
