Product information

Description

The Ajax DoorProtect is a professional-grade wireless magnetic contact sensor engineered to provide reliable perimeter security for residential and commercial properties. Designed to detect the opening of doors and windows, this device serves as a critical component of the Ajax security ecosystem. Its sleek black finish allows it to blend discreetly into modern interiors while offering robust protection against unauthorized entry.

Advantages

This sensor stands out due to its exceptional energy efficiency, capable of operating for up to 84 months on a single CR123A battery. It features advanced authentication technology to prevent forgery, along with sophisticated jamming detection and encrypted communication channels to ensure system integrity. The inclusion of two different magnet sizes provides flexibility for installation on various frame types, including narrow frames and metal surfaces. Furthermore, the device supports an external contact, allowing users to connect additional third-party wired detectors to the system.

Suitable for

  • Residential door and window security
  • Commercial office perimeter monitoring
  • Securing metal doors and narrow window frames
  • Integration with existing Ajax security hubs

When it may not be suitable

The Ajax DoorProtect is designed specifically for use within the Ajax security ecosystem and requires a compatible Ajax hub to function. It is not a standalone device and cannot be integrated into third-party alarm systems that do not support the Ajax wireless protocol.

Key specifications

  • Wireless connectivity via RF
  • Maximum outdoor range of 1200 meters
  • Battery type: CR123A (3V)
  • Battery life: Up to 84 months
  • Dimensions: 20 mm x 20 mm x 90 mm
  • Tamper protection alarm
  • Includes two magnets for varied installation distances

How to use

The device is ready for immediate use out of the box with the battery pre-installed. To set it up, simply add the sensor to your Ajax hub via the mobile application with a single click. The sensor consists of two modules: the main detector and the magnet. Mount the SmartBracket to your chosen surface, then attach the detector. Position the magnet within the recommended distance—up to 2 cm for the large magnet or 1 cm for the small magnet—to ensure accurate detection of opening events.

What to consider before purchase

  • Ensure you have an Ajax hub installed to manage the sensor
  • Verify the distance between the magnet and the detector before permanent mounting
  • Check if your installation surface requires the large or small magnet provided

Usage recommendations

For optimal performance, regularly check the signal strength and battery status through the Ajax mobile application. Ensure the sensor is mounted securely on a stable surface to prevent false triggers caused by vibrations.
