Ajax DoorProtect Universal Door and Window Opening Sensor

The Ajax DoorProtect Black is a wireless magnetic opening detector designed for installation on doors and windows to instantly signal their opening. It's a crucial element in the Ajax smart security system, ensuring a rapid response to potential intrusions. Thanks to its black color, the detector discreetly blends into modern interiors.

The detector consists of two parts: the main unit with a reed switch and a magnet. When a door or window is opened, the magnet moves away from the main unit, breaking the magnetic field and triggering an alarm. The set includes two magnets of different sizes – a large magnet that operates up to 2 cm away, and a small magnet that operates up to 1 cm away. This provides flexible installation options for various types and thicknesses of frames and door leaves.

Ajax DoorProtect utilizes Ajax's proprietary Jeweller radio technology , ensuring secure and encrypted two-way communication with the Ajax Hub up to 1200 meters in open space . This guarantees lightning-fast alarm signal delivery – in just approximately 0.15 seconds . The detector is equipped with tamper protection , which immediately reports any attempts to detach it from the SmartBracket mounting panel or open its casing, thus providing high anti-sabotage protection. The device operates on a pre-installed CR123A battery, offering an excellent operating life of up to 7 years , minimizing maintenance needs. Furthermore, it features an external contact (NC type) , allowing for the connection of third-party wired detectors, expanding the system's functionality.
