AJAX DoorProtect Plus Wireless Opening Detector
Introduction
Door Protect Plus is a wireless security device which detects opening, shocks, and tilting. It has a socket for connecting an external detector.
Door Protect Plus is connected to the Ajax security system via the protected Jeweller protocol, with an effective communication range of up to 1,200 meters without obstacles. Can operate up to 5 years from a preinstalled battery and is furnished with a sealed contact reed relay
processing more than one million openings. It has a socket for connecting an external detector
Sealed contact reed relay is a device which forms a continuous circuit under the effect of a constant magnet. It consists of ferromagnetic contacts placed in a bulb.
The detector is set up via a mobile application for iOS and Android-based smartphones. The user is notified of all events through push notifications, SMS messages and calls (if activated).
Not compatible with the uartBridge or ocBridge Plus
The Ajax security system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

Door Protect Plus Operating Principle
Door Protect Plus consists of the detector with a sealed contact reed relay, and a constant magnet. The detector is equipped with two magnets – small and big, with the magnet operation ranges of 1 and 2 cm accordingly. The detector is attached to a moving wing or sliding part and the magnet – to a frame. If the sealed contact reed relay is within the coverage area of the magnetic field, it closes the circuit – the detector is closed. The opening of the wing distances the magnet from the sealed contact reed relay, resulting in the circuit opening, and the detector records opening.
The detector may be positioned horizontally. If there is no need to detect opening with the sealed contact reed relay, please use only an electronics unit (without magnets) and disable the magnetic sensor in the settings.
Tilt detector detects the vertical deviation of the device relative to the initial position of more than 5°. Door Protect Plus can be installed on windows including dormer windows, and the system can be armed, when they are in the airing mode (you should рreviously disable the magnetic sensor in the settings).
After actuation, the Door Protect Plus detector set in the intrusion detection mode immediately transmits an alarm signal to the Ajax hub, activating the sirens connected to the hub and notifying the user and private security company.
Detector Connection to hub
Before starting connection
- Following the hub instruction recommendations, install the Ajax application on your smartphone. Create an account, add the hub to the application, and create at least one room.
- Go to the Ajax application.
- Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
- Ensure that the hub is disarmed and does not start updates by checking its status in the mobile application.
Only users with administrative privileges can add the device to the hub
How to connect the detector to the hub
- Select the Add Device option in the Ajax application.
- Name the device, scan/write manually the QR Code (located on the body and packaging), and select the location room.
- Select Add — the countdown will begin.

Performance testing
The Ajax security system allows conducting tests for checking the functionality of connected devices.
The tests do not start straight away but within a period of 36 seconds when using the standard settings. The test time start depends on the settings of the detector scanning period (the paragraph on “Jeweler” settings in hub settings).

Attenuation Test
Selection of the Detector Location
Location of the Door Protect Plus detector determines its remoteness from the hub and presence of any obstacles between the devices hindering the radio signal transmission: walls, interfloor bridgings, large-size objects located within the room.
Check the signal strength at the installation site
If the signal strength reaches just one bar on the indicator, the stable operation of the security system can not be guaranteed. Take whatever action is necessary to improve the quality of the signal! At the very least, move the device — relocation even by 20 cm can significantly improve the reception quality.
If, after moving, the device still has a low or unstable signal strength, use a radio signal range extender ReX.
Do not install the detector:
- outside the room (outdoors);
- nearby any metal objects or mirrors causing attenuation and screening of the signal;
- within any premises with the temperature and humidity beyond the range of permissible limits;
- closer than 1 m from the hub.
The magnet is attached to the right of the detector. The detector is located either inside or outside the door case (window frame):
When installing the detector in the perpendicular planes (inside the case/frame), use the small magnet from the set. The distance between the magnet and detector should not exceed 1 cm.
When positioning the parts of Door Protect Plus in the same plane, use the big magnet. Its actuation threshold – 2 cm.
Detector Testing
Having defined the location, fix the detector and magnet with a double-sided adhesive tape and check the operation of the device using the detection zone test.
While in the test mode, the Door Protect light indicator lights continuously, however switching off for a second, if the detector is actuated. Check correct operation of the device by opening/closing the wing several times.
Connection of external detector
An external wired detector with an NC type contact may be connected to the DoorProtect Plus using an outside-mounted terminal clamp.
We recommend to install the wire detector at a distance not exceeding 1 meter – increasing the wire length will increase the risk of its damage and reduce the quality of communication between the detectors.
To lead out the wire from the detector body, break out the plug:
If the external detector is actuated, you will receive the respective notice.
To make sure an alarm is raised when the roller shutter is opened, connect a wired roller shutter motion detector with an NC (normally closed) contact to Door Protect Plus.
How to connect the roller shutter motion detector to DoorProtect Plus
Installation of the Detector
Before installing the detector, make sure that you have selected the optimal location and it is in compliance with the guidelines contained in this manual!
- Fix the Smart Bracket attachment panels of the detector and magnet using bundled screws. If using any other attachment hardware, make sure that they do not damage or deform the panel.
The double-sided adhesive tape may be only used for temporary attachment of the detector and magnet. The tape will run dry in course of time, which may result in falling of Door Protect Plus and actuation of the security system. Furthermore, the device may fail from a hit. - Put the detector on the attachment panel. As soon as the detector is fixed in Smart Bracket, it will blink with a LED – this will be a signal that the tamper on the detector is closed. If the light indicator of the detector is not actuated after installation in Smart Bracket, check the status of the tamper in the Ajax Security System application and then the fixing tightness of the panel.
If the detector is torn off from the surface or removed from the attachment panel, you will receive the notification. - Put the magnet on the attachment panel.
Detector Maintenance and Battery Replacement
Check the operational capability of the Door Protect Plus detector on a regular basis.
Clean the detector body from dust, spider web and other contaminations as they appear. Use soft dry napkin suitable for equipment maintenance.
Do not use for cleaning the detector any substances containing alcohol, acetone, gasoline and other active solvents.
The service life of the detector from the battery depends on battery quality, the actuation frequency of the detector and inquiry interval of the detectors by the hub.
If the door opens 10 times a day and the detector inquiry interval is set at 60 seconds, then Door Protect will operate 5 years from the pre-installed battery. You will reduce the service life of the device to 2 years by setting the inquiry interval at 12 seconds.
If the detector battery is discharged, the user will receive a notice, and the
LED will smoothly light up and go down if the detector or tamper is actuated.
