Advanced 3-in-1 Protection for Every Entry Point

Secure your home or business with the AJAX DoorProtect Plus Jeweller, a sophisticated wireless detector that offers three layers of security for any door or window. This device instantly detects opening, shock, and changes in tilt, providing comprehensive protection against intrusion. Its advanced sensors are designed to protect even windows left open for ventilation, as the built-in accelerometer will register vibrations, impacts from attempted force, or any change in vertical angle. Housed in a sleek black casing, it seamlessly blends with your interior while offering powerful, professional-grade security.

Key Features:

  • Triple-Sensor Detection: Combines a high-end reed switch for opening detection with a sensitive accelerometer that registers shock, vibration, and tilt. The tilt sensor's activation threshold is adjustable from 5° to 25°.
  • Jeweller Wireless Technology: Employs Ajax's proprietary Jeweller radio technology for secure, encrypted two-way communication with the hub at a distance of up to 1,200 meters in open space. It features frequency hopping to prevent jamming and ensure reliable alarm delivery.
  • Adjustable Sensitivity: The shock sensor has three adjustable sensitivity levels, allowing you to fine-tune the detector to your specific environment and prevent false alarms.
  • External Detector Input: Includes a terminal for connecting a third-party wired detector with a normally closed (NC) contact type, expanding your security system's capabilities.
  • Long Battery Life: Operates for up to 5 years on the pre-installed CR123A battery, minimizing maintenance. The system will notify you well in advance when the battery needs replacing.
  • Effortless Installation: Ready to work straight out of the box. The SmartBracket mount allows for quick, easy installation without disassembling the detector's body. Connecting to an Ajax hub is as simple as scanning a QR code with the app.

How It Works

The DoorProtect Plus consists of two parts: the detector and a magnet. The opening is detected by a British-made reed switch when the magnet moves away from the sensor. Simultaneously, the integrated accelerometer stands guard against forced entry attempts by detecting vibrations and impacts, or if an intruder tries to open a window that is tilted for ventilation. In case of any event, an alarm signal is sent to the Ajax hub in just 0.15 seconds.

Soft and cozy
Color: Tie-dye Cream Beige, Size: Twin(60"x80")
Recieved last week. The texture is soft and warm. Love it so far. The beige color is a little more greige than I expected but it still goes well with my decor.

Amazing blanket. Definitely recommend!!😊
Color: Tie-dye Sage, Size: Twin(60"x80")
Best blanket ever. I got it for an Amazon a lightning deal for 55% off! It was only 22 dollars and this is the most comfortable blankets ever. It is very soft and it keeps me very warm. I would definitely recommend it, it's even more beautiful in person. It's very high quality, and it's lightweight but keeps you warm. Though I wish they would lower the price, because it's 70 dollars to buy another one. But still an amazing blanket, 5 stars for me!!! 😊😊🥰🥰😍😍🤗🤗💗💞

Fabulous and sooooo soft
Color: Tie-dye Khaki, Size: Throw(50"x60"), Color: Tie-dye Khaki, Size: Throw(50"x60")
This blanket is so extremely soft and cozy. The only reason I deducted a star was because the fur side and the velvety side aren’t sew together anywhere besides the edges/seams, so when I fold it it’s basically like 2 blankets just sewn together and not one blanket. When you lie with it and cover you, they sort of separate if that makes sense but it doesn’t bother us. It’s so comfy to have on the couch and while movie watching. The only time it sort of a pain is when I fold it. In saying that, I would buy again. The velvety side is a soft tan/beige and the fur side is creams, off white and variations of the tan/beiges. So lovely. You can see it next to a solid cream colored blanket I have that I also bought on Amazon. It matches well and I love it!

This one is really soft
Color: Tie-dye Khaki, Size: Throw(50"x60")
This is actually baby bunny soft! I was very pleasantly surprised. The top side is plush and the bottom side is smooth but in a velvety suede type smooth. It is very well made and after machine washing and drying it several times it still looks and feels new.
