AJAX DOOR PROTECT - BLACK
Wireless opening detector that notifies of first signs of room intrusion by means of a broken door or window. It can be mounted on all types of doors including a metal base.
- Authentication to prevent forgery
- Jamming detection and communication channels encryption
- Tampering alarm
- Operates up to 7 years without battery replacement
- External contact is available for connecting third-party detectors
- Includes magnets of various sizes for installation on narrow frames and door frames
Principle of operation
The device detects the door or window being opened by means of British-made hi-end reed switches on which the magnetic field acts. It can operate in the transmitter mode, sending a signal from the wired sensor to the hub.
Features
The device consists of two modules — detector and magnet. The set includes two magnets: the big magnet is installed at a distance of up to 2 cm, and the small magnet up to 1 cm.
Installation and set up
Ready to operate straight out the box: the battery is already installed, therefore there is no need to disassemble the detector. With one click, it can be connected to the hub in the mobile application. It can be mounted on the SmartBracket in just a few minutes.

Maximum effective radiated power (ERP)
up to 20 mW
Automatic power control to reduce power consumption and noise interference.
Radio signal modulation
GFSK
Radio signal range
up to 1,200 m
Between detector and control panel (or range extender) in an open space.
Encrypted communication
All the data stored and transmitted are protected by block encryption with a dynamic key.
Frequency hopping
Radio communication uses frequency hopping to prevent interception and jamming.
Detection
Sensitive element
1 reed switch
Magnets
small and big one come in the set
The small magnet operates at a distance of up to 1 cm from the detector, and the big magnet — up to 2 cm. Attach the magnet on the right side of the detector.
Protection against reed switch chattering
The detector ignores vibrations lasting up to 0.15 s.
Input to connect an additional detector
Wired detector with the normally closed (NC) contact type.
Chime
When the system is disarmed, the siren makes a special sound to notify that the opening detectors are triggered.
Recommendations
Do not install the detector using both magnets at the same time. The detector recognizes only one magnet on one side of the detector.
Attach the magnet to the moving part of the door (window) to the right of the detector. The side to which the magnet should be attached is marked with an arrow on the detector’s enclosure.
The device is designed for indoor use only.
Sabotage protection
Tamper alarm
Notifications on attempts to detach the detector from the surface or remove it from the mounting panel.
Protection against spoofing
device authentication
Communication loss detection
after 36 s
Depends on the Jeweller or Jeweller/Fibra settings.
