Ajax CombiProtect Fibra Black Wired Motion & Glass Break Detector

Ajax CombiProtect Fibra Black Wired Motion & Glass Break Detector

The Ajax CombiProtect Fibra combines a PIR motion sensor and an acoustic glass-break sensor in a single wired device, giving installers a space-saving way to protect rooms with windows or glazed doors. Built for the Ajax Fibra wired ecosystem, it delivers the tamper resistance and long cable runs of a hardwired system while still offering the flexible, app-based configuration Ajax is known for. The black finish suits modern interiors and darker window frames where a discreet detector is preferred.

Key Features

• Dual detection in one housing: combines a PIR motion sensor with an electret microphone for glass-break detection, reducing the number of devices needed per room.
• Long motion range: detects movement at distances of up to 12 metres.
• Glass-break coverage: listens for breaking glass at distances of up to 9 metres.
• DualTone verification algorithm: requires both the low-frequency impact sound and the high-frequency shatter sound within 1.5 seconds before triggering an alarm, cutting down false alerts.
• Pet-friendly design: ignores pets up to roughly 20 kg and 50 cm in height.
• Adjustable sensitivity: three sensitivity levels can be set remotely from the Ajax app to suit different environments.
• Robust Fibra wired connection: communicates over a secure, two-way wired Fibra bus with a range of up to 2,000 m using standard U/UTP cat.5 twisted-pair cable.
• Anti-sabotage protection: the SmartBracket mounting panel includes a perforated tamper section that triggers an alert if the detector is pried from the wall.
• Indoor installation: designed for wall or corner mounting, ideally at around 2.4 m height, with the lens aimed perpendicular to the likely intrusion path.

Reliable Room-Level Protection for Homes and Businesses

Because it merges two sensor types into one enclosure, the CombiProtect Fibra is well suited to rooms with multiple windows or glazed doors, such as offices, retail storefronts, living rooms and hallways, where installing separate motion and glass-break detectors would be impractical. As part of a wired Fibra Ajax system, it suits sites where reliable cabled connectivity is preferred over wireless, such as larger commercial premises or installations requiring long cable runs between the hub and detector.

Frequently Asked Questions

Does the CombiProtect Fibra work wirelessly?
No. This is a wired detector that connects to a compatible Ajax hub over the Fibra bus using standard network cable, rather than a radio-frequency Jeweller connection.

Will it false-alarm from a barking dog or passing traffic?
The DualTone glass-break algorithm and pet-immunity design are built to filter out common everyday sounds and small animal movement, though correct installation height and positioning are important for best performance.

Can it detect glass break through window film?
No. Glass fitted with shockproof, sun-protective, decorative or other film may not trigger a glass-break alarm; a shock/tilt detector is recommended for such glazing.
