Ajax DoorProtect Plus White Wireless Door & Window Sensor with Shock/Tilt

Ajax DoorProtect Plus (White) – Wireless Opening, Shock & Tilt Detector

The Ajax DoorProtect Plus is a wireless indoor detector that combines a magnetic reed switch with a built-in accelerometer, giving you three layers of protection in a single compact device. It reports door and window openings, detects shocks or attempts to force an entry point, and senses tilt movement, making it a versatile choice for securing doors, windows, skylights, cabinets and small vaults. It communicates with an Ajax hub over the encrypted, long-range Jeweller radio protocol and is finished in white to blend with light-coloured door and window frames.

Key Features

• Triple detection: reed switch for opening/closing plus an accelerometer for shock and tilt sensing in one housing
• Long wireless range: communicates with the hub over the secure Jeweller protocol at distances of up to 1,200 metres in open space
• Ventilation mode support: can be mounted on a window and left armed while the window is tilted open, only alarming if the tilt angle exceeds the configured threshold
• Adjustable sensitivity: shock and tilt thresholds can be tuned in the Ajax app to reduce false alarms from wind, traffic or nearby vibration
• Two magnets included: a small magnet for perpendicular mounting and a large magnet for same-plane mounting, giving flexible installation options
• Wired input for expansion: includes a terminal for connecting an additional third-party NC (normally closed) wired detector
• Long battery life: runs on a single pre-installed CR123A battery rated for up to 5 years of use
• Tamper protection: an internal tamper button triggers an alert if the enclosure is opened or the unit is pried off its mounting bracket
• Easy installation: ships pre-configured and ready to pair with the SmartBracket mounting panel, no wiring or disassembly required

Reliable Protection for Entry Points

DoorProtect Plus is designed for indoor use on the entry points intruders target most often, including front and back doors, ground-floor windows, skylights and storage cabinets. Because it senses shock and tilt in addition to opening, it can flag attempts to jimmy, lift or shift a door or window frame even before it is fully opened, and it keeps working as a tilt sensor when a window is propped open for airing. It pairs with any compatible Ajax hub as part of a broader wireless alarm system alongside motion detectors, sirens and smart home accessories.

Frequently Asked Questions

Does DoorProtect Plus work on windows left open for ventilation?
Yes. The magnetic sensor can be disabled while the accelerometer continues to monitor tilt, so the system can stay armed with a window slightly open and still alert on excessive movement.

How long does the battery last?
It ships with a pre-installed CR123A battery rated for up to 5 years of typical use, with low-battery warnings sent to the Ajax app well in advance.

Can I connect an existing wired sensor to it?
Yes, it has a terminal for a third-party wired detector with a normally closed (NC) contact, letting you bring existing wired sensors into an Ajax wireless system.
