Ajax CombiProtect White Wireless Motion & Glass Break Detector

Ajax CombiProtect White Wireless Motion & Glass Break Detector

The Ajax CombiProtect combines a passive infrared motion sensor and an acoustic glass break detector into a single compact wireless unit, giving you dual-layer protection for any room with a window. Built on Ajax's encrypted Jeweller radio protocol, it links back to an Ajax hub to deliver fast, reliable alerts the moment an intruder is detected moving through a room or attempting to force a window, while smart filtering keeps household pets from triggering false alarms.

Key Features

• Dual detection technology: a thermal PIR sensor tracks human movement while a dedicated microphone listens for the distinct sound of breaking glass.
• Two-stage glass break verification: the DualTone algorithm confirms an alarm only after detecting both the low-frequency impact and the high-frequency shatter of glass within 1.5 seconds, reducing nuisance triggers.
• Pet-friendly design: ignores animals weighing up to roughly 20 kg and under 50 cm tall when installed at the recommended height.
• Long detection range: senses motion up to 12 metres away and glass breakage up to 9 metres from the window.
• Adjustable sensitivity: three configurable sensitivity levels let installers tailor performance to the specific room and household.
• Encrypted wireless link: the Jeweller protocol provides two-way, tamper-resistant communication with a range of up to 1,200 metres in open space.
• Long battery life: runs on a single pre-installed CR123A battery rated for years of use, minimising maintenance visits.
• Tool-free installation: mounts on the included SmartBracket panel without needing to open the housing, and pairs with the hub instantly via QR code scan.
• Environmental compensation: built-in temperature adjustment maintains accurate motion sensing even in warmer climates.

Reliable Coverage for Homes and Small Businesses

Because it protects both the door/window opening and the glass itself, the CombiProtect is well suited to lounges, bedrooms, offices, retail counters and any space with a single window and entry point that needs consolidated coverage from one device. Its pet immunity and noise filtering make it a practical choice for households with cats or small dogs, while its indoor-rated tamper protection and remote configuration through the Ajax app make it easy for installers to fine-tune after fitting.

Frequently Asked Questions

Does it need a separate glass break sensor? No, the acoustic microphone and PIR motion sensor are combined in one housing, so a single device covers both threats.

Will it false-alarm on my pet? When mounted at the recommended height and angle, it is designed to ignore pets under roughly 20 kg and 50 cm tall.

Can it work with laminated or film-coated glass? It is optimised for standard untreated glass; shockproof or decorative film can dampen the sound signature and reduce detection reliability.

What hub do I need? It requires an Ajax hub or a compatible range extender/bridge running the Jeweller radio protocol to operate.
