DoorProtect Jeweller

The DoorProtect Jeweller is a wireless opening detector designed to protect doors, windows, and skylights. Its high-quality reed switch is manufactured in Britain and withstands over 2 million openings. The system includes two magnets of different sizes for flexible installation, even on narrow frames, while the pre-installed battery offers up to 7 years of operation without the need for replacement.

Reed Switch

The reed switch is the main functional component of the device, housed in a durable plastic capsule that protects against shocks and drops, ensuring long-term reliability. The device can accurately detect breaches, while the protection against "friction" of the reed switch prevents false alarms.

Additional Connectivity Options

The DoorProtect Jeweller offers additional connectivity options with third-party NC-type detectors, such as opening, vibration, or motion detectors, enhancing the overall security of the system. The Chime function turns the detector into an electronic doorbell, with sound notifications of different patterns for each entrance, which can be customized through the Ajax app.

Jeweller Technology by Ajax

The device uses Ajax's innovative Jeweller wireless technology, which provides secure two-way communication with encryption and device authentication, protection against interference, and adjustable power capability. The system supports a range of up to 1,200 meters in open space and can be extended with ReX repeaters for stable operation even in large or complex installations.

Simple & Quick Installation

Installation is simple and quick using the SmartBracket and the Ajax app, without the need to disassemble the device. The device continuously reports its status to the Ajax hub and the app, providing real-time notifications for any error or tampering attempt, ensuring complete supervision and reliability.

    The second contact should be able to be programmed for night operation separately from the main one. It's excessive to have to buy the more expensive model for this job.

    The contact is the best available in wireless and with a battery that lasts 3 to 5 years. It is the best available in a wireless system, as a certified installer I recommend it. I also undertake the installation and configuration of the system.

    This review is about the colour: Black

    The installation is very easy, as well as the alignment thanks to the removable adhesive. The base could hold the sensor better because it can turn 2-3 degrees left or right, affecting the aesthetics of the image, although it is not important, I just mention it. Its reliability seems excellent. Ideal for doors. For windows and balcony doors, I recommend spending a few extra euros on the Ajax DoorProtect Plus Magnetic Door and Window Detector with Tilt and Vibration Sensor.

    Use the wired trap kit that includes.
    And if you can, install recessed traps for added convenience.
    Always screw the transmitter (trap) onto the wall, do not rely on double-sided tape.
    That's why it's a perfect product.

    This review is about the colour: Black

    Very easy to install them in the already very easy DIY (do it yourself) installed alarm system, which sends notifications via the Internet and SMS to the mobile phone within a fraction of a second after activation. To send SMS, the placement of a SIM card is required in the central unit. Very easy customization of the operation of the individual sections of the alarm through the application from the mobile phone.

    Very good for its job. The only disadvantage it has, which causes it to lose one star, is that the large magnet only works up to a distance of 2cm, but it needs to be at a distance of 1cm to function properly.
