Ajax DoorProtect Plus Fibra White Wired Opening, Shock & Tilt Detector

Ajax DoorProtect Plus Fibra White Wired Opening, Shock & Tilt Detector

The Ajax DoorProtect Plus Fibra is a wired magnetic contact detector built for professional intrusion protection on doors, windows, skylights, cabinets, and vaults. Part of the Ajax Fibra wired product line, it combines a dual reed switch opening sensor with a built-in accelerometer that detects shock, vibration, and tilt, giving installers a single compact device that covers multiple threat types on one opening point. Finished in white, it blends into most interior door and window frames.

Key Features

• Dual reed switch design lets the magnet be fitted on either the left or right side of the detector for flexible installation.
• Two magnet sizes included (small and large) so installers can choose the best fit depending on frame gap and mounting surface.
• Built-in accelerometer detects shock and vibration from attempted forced entry, such as prying or drilling near a lock.
• Adjustable tilt detection allows the sensor to arm a window in ventilation mode while still catching abnormal tilt angles.
• Fibra wired protocol provides fast, reliable two-way communication with the hub over a standard 4-wire cable, with lines supporting up to 2,000 metres.
• Anti-chatter protection on the reed switches reduces false alarms caused by vibration or loose-fitting doors.
• Third-party detector input lets installers connect an external wired NC sensor to extend protection from the same device.
• Durable, tamper-resistant construction designed for long-term reliability in indoor security installations.

Reliable Wired Protection for Demanding Installations

This detector suits homes, offices, retail stores, and commercial premises where a hardwired sensor is preferred over battery-powered alternatives, such as sites with existing cabling infrastructure or where installers want to avoid periodic battery replacement. It is commonly fitted on entry doors, ground-floor windows, roller shutters, and skylights as part of a larger Ajax Fibra wired security system, working alongside hubs and other Fibra line devices for centralised monitoring and control through the Ajax app.
