Product information

Description

Ajax DoorProtect Plus Black is a wireless, battery-powered magnetic opening detector with built-in tilt and shock sensors. Designed for indoor use, the device detects door and window opening, inclination relative to the ground and impacts. It connects to an Ajax Hub via the Jeweller radio protocol and supports an external wired detector input, providing reliable intrusion detection for homes and small businesses.

Advantages

DoorProtect Plus communicates with the Ajax Hub over a secure, encrypted channel with frequency-hopping and anti-jamming features. The detector uses a British-made reed switch rated for over 1,000,000 actuations and an accelerometer that senses vibration and impacts. It supports authentication and tamper protection, adjustable signal polling intervals (12–300 seconds), and power saving that extends battery life up to 5 years under typical settings. The unit can be tested and configured remotely and pairs with the hub in one click.

Suitable for

  • Monitoring doors in houses and apartments
  • Protecting windows and balcony doors across several floors
  • Securing office entry points and server rooms
  • Integration with Ajax security systems requiring wired detector input

How to use

Install the main unit and magnet on a flat surface using the SmartBracket mount; the body does not need to be disassembled for installation. Position the magnet within the specified distance (up to 1 cm with the small magnet or up to 2 cm with the big magnet) from the main unit. Insert the pre-installed CR123A battery if required and connect the detector to the Ajax Hub with a single click through the Ajax mobile app. If needed, connect an external wired detector to the additional input. Verify connection quality and detection area remotely using the hub’s test functions.

Usage recommendations

Place the detector indoors on doors or windows away from direct moisture and extreme temperatures; test the magnet alignment and signal strength after installation and set the ping interval and alarm parameters in the Ajax app according to the site’s security requirements.
