Ajax CombiProtect Black Wireless Motion & Glass Break Detector

Ajax CombiProtect Black - Wireless Motion and Glass Break Detector

The Ajax CombiProtect is a dual-purpose wireless sensor that merges motion detection and acoustic glass break detection into a single compact enclosure. Designed for the Ajax Jeweller ecosystem, it watches over a room's open floor space while simultaneously listening for the distinct sound signature of shattering glass on nearby windows or doors, making it an efficient way to cover two threat types with one device and one mounting point.

Key Features

• Combined detection: Merges a PIR motion sensor and an acoustic glass break sensor in one unit, reducing the number of devices needed per room.
• Motion range: Detects movement at distances up to 12 metres with an 88.5° horizontal and 80° vertical field of view.
• Glass break range: Picks up glass breakage from up to 9 metres using a sensitive electret microphone.
• Pet-friendly design: The SmartDetect algorithm and FresnelTech lens help the sensor ignore pets weighing up to 20 kg and under 50 cm tall, cutting down on false alarms.
• DualTone verification: Glass break alarms are only triggered after detecting both a low-frequency impact sound and a high-frequency shatter sound within 1.5 seconds, filtering out noise from thunder, barking, or traffic.
• Temperature compensation: Maintains accurate motion detection even in warmer indoor climates.
• Long battery life: Runs on a pre-installed CR123A battery rated for up to 5 years of use.
• Secure Jeweller connectivity: Encrypted two-way wireless communication with the Ajax hub, with a line-of-sight range of up to 1,200 metres.
• Fast, tool-free mounting: Attaches via the SmartBracket panel without needing to open the detector housing, and includes tamper protection against removal attempts.

Where to Use It

The CombiProtect in black is well suited to living rooms, offices, retail floors, or any single room featuring both open space and a window or glass door that needs safeguarding. Because it handles motion and glass break monitoring together, it is a practical choice for smaller rooms or budget-conscious installations where fitting two separate detectors isn't necessary. Mounting at roughly 2.4 metres with the lens aimed across the likely intrusion path gives the most reliable results for both detection types.

Frequently Asked Questions

Does the CombiProtect work with all types of glass?
It detects standard glass breakage well, but it will not reliably trigger on glass treated with shockproof, tinted, or decorative film, since that film changes how the glass sounds when it breaks.

Will my pets set off false alarms?
When installed correctly, the detector is designed to ignore pets up to 20 kg in weight and under 50 cm in height, though correct mounting height and angle are important for this to work well.

Can it be used outdoors?
No, this detector is built for indoor use only and should be installed inside the premises it is protecting.
