Ajax DoorProtect Plus (Jeweller) – Wireless Opening, Shock & Tilt Detector (White, 9NA)

Product Overview

The Ajax DoorProtect Plus 28269.13.WH3, 9NA region frequency is an advanced wireless opening detector with integrated shock, vibration, and tilt sensing capabilities, designed to safeguard doors, windows, skylights, and roof hatches within the Ajax security ecosystem. In addition to conventional magnetic contact detection, it utilizes an onboard 3-axis accelerometer that immediately registers physical impacts, forced entry attempts, and tilt angle changes exceeding 5°.

Communicating via the proprietary Jeweller wireless radio protocol across distances up to 1,200 meters in open space, DoorProtect Plus allows windows to remain open in ventilation mode while still maintaining an active perimeter alarm state. Equipped with two interchangeable magnets, an external wired contact input (NC), and a pre-installed CR123A battery delivering up to 5 years of autonomous operation, it provides comprehensive perimeter intrusion protection in a clean white finish.

Key System Features & Functionality

• Triple Intrusion Detection: Combines precise magnetic opening detection, vibration/shock sensing, and tilt angle monitoring (> 5°) in a single compact housing.

• Ventilation Mode Arming: Enables arming while windows are left partially tilted open for air circulation, triggering an alarm only if the window is tilted further, opened, or struck.

• Shock & Impact Sensor: Built-in accelerometer detects forced entry, drilling, and structural impacts before an intruder breaches the entryway.

• Jeweller Wireless Technology: Two-way encrypted radio communication operating up to 1,200 meters (3,900 ft) line-of-sight with anti-jamming frequency hopping.

• External NC Contact Input: Onboard terminal block allows integration of third-party wired sensors or roller shutter contacts.

• Up to 5 Years Battery Life: Powered by a pre-installed CR123A lithium battery with intelligent energy management.
