Ajax DoorProtect Jeweller Wireless Magnetic Detector for Doors and Windows

The Ajax DoorProtect Jeweller AJ-DOORPROTECT-B is a wireless magnetic detector designed to enhance perimeter security on doors, windows, and skylights with a fast, reliable, and professional installation. Thanks to its Jeweller technology and highly stable communication, it provides an effective solution for homes, businesses, and professional intrusion protection projects.

This detector features a British-made reed relay engineered to withstand more than 2 million openings, ensuring accurate and long-lasting detection even in high-traffic installations. It also includes bounce protection for improved operational stability and reduced false alarms. Its wireless Jeweller system enables secure communication with the Ajax hub at distances of up to 1,200 meters in open space.

The DoorProtect Jeweller includes two different-sized magnets to easily adapt to narrow frames or complex door and window installations. It also integrates NC terminals for connecting third-party wired detectors, providing great versatility in upgrade or expansion projects for existing alarm systems. It is especially useful for installers who need to keep existing sensors while migrating to a professional Ajax wireless solution.

Thanks to its automatic supervision, the system can report device status, low battery alerts, or maintenance requirements directly through the Ajax app. The detector also incorporates an anti-tamper switch and remote configuration via QR code, making it ideal for both new installations and upgrades of wireless perimeter security systems.

In summary, the Ajax DoorProtect Jeweller AJ-DOORPROTECT-B combines reliability, long battery life, and installation flexibility to protect access points in a professional and secure way across all types of environments.

Extended Information about the Ajax Jeweller Black Magnetic Contact for Door/Window

Practical Applications of the Ajax Jeweller Black Magnetic Contact for Door/Window

Example 1. Wireless perimeter protection in homes or offices:

The DoorProtect Jeweller can be installed on main doors, balconies, and windows to instantly detect unauthorized openings. Thanks to its Jeweller wireless communication technology and battery life of up to 7 years, it enables the creation of professional security systems without the need for construction work or additional wiring. In addition, it can continuously communicate and notify users about intrusions or sudden impacts detected in the protected area, providing constant supervision and improving security in an efficient and reliable way.

Example 2. Hybrid integration in existing alarm systems:

In commercial installations, residences, offices, or retail stores, this Ajax detector is especially useful for integrating existing wired sensors through its additional NC input. Thanks to this feature, installers can modernize older alarm systems by incorporating Ajax wireless technology without replacing all previously installed detectors, significantly reducing upgrade costs and installation time.

This solution is commonly used in nursing homes, small retail businesses, or office buildings where operational wired magnetic contacts are already installed and there is a need to upgrade the alarm control panel without construction work or major infrastructure modifications. In addition to reusing existing sensors, the system allows users to benefit from Ajax features such as remote supervision, instant notifications, and secure Jeweller communication, improving both reliability and overall system control.
