Ajax Systems DoorProtect Wireless Door and Window Opening Detector User Manual

DoorProtect is a wireless door and window opening detector designed for indoor use. It is capable of detecting more than 2 millions openings. DoorProtect has a socket for connecting an external detector.

The functional element of DoorProtect is a sealed contact reed relay. It consists of ferromagnetic contacts placed in a bulb that form a continuous circuit under the effect of a constant magnet.

DoorProtect operates within the Ajax system, connecting via the protected Jeweller radio protocol. Communication range is up to 1,200 m in the line of sight. Using the uartBridge or ocBridge Plus integration modules, DoorProtect can be used as part of third party security systems. The detector is set up via Ajax apps for iOS, Android, macOS and Windows. The app notifies user of all events through push notifications, SMS and calls (if activated).

The Ajax system is self-sustaining, but the user can connect it to the central monitoring station of a private security company.

Operating principle

DoorProtect consists of two parts: the detector with a sealed contact reed relay, and the constant magnet. Attach the detector to the door frame, while the magnet can be attached to the moving wing or sliding part of the door. If the sealed contact reed relay is within the coverage area of the magnetic ﬁeld, it closes the circuit, which means that the detector is closed. The opening of the door pushes out the magnet from the sealed contact reed relay and opening the circuit. In such a way, the detector recognizes the opening.

Attach the magnet to the RIGHT of the detector.
A small magnet works at a distance of 1 cm, and the big one — up to 2 cm.

After actuation, DoorProtect immediately transmits the alarm signal to the hub, activating the sirens and notifying the user and security company.

Pairing the Detector

Before starting pairing

Following the hub instruction recommendations, install the Ajax app on your smartphone. Create an account, add the hub to the app, and create at least one room.
Switch on the hub and check the internet connection (via Ethernet cable and/or GSM network).
Make sure that the hub is disarmed and does not update by checking its status in the app.

Only users with administrator rights can add the device to the hub.

How to pair the detector with the hub:

Select the Add Device option in the Ajax app.
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.
Switch on the device.

For detection and pairing to occur, the detector should be located within the coverage area of the wireless network of the hub (at the same facility).
The request for connection to the hub is transmitted for a short period of time at the moment of switching on the device.
If pairing with the hub failed, switch off the detector for 5 seconds and retry it.
If the detector has paired with the hub, it will appear in the list of devices in the Ajax app. The update of the detectors statuses in the list depends on the detector ping interval set in the hub settings. The default value is 36 seconds.

Functionality Testing
The Ajax system allows conducting tests for checking the functionality of connected devices.
The tests do not start immediately but within 36 seconds by default. The starting time depends on the ping interval (the paragraph on “Jeweller” settings in hub settings).

Detection Zone Test
Attenuation Test

Installing the Detector

Selecting the location
Location of DoorProtect is determined by its remoteness from the hub and presence of any obstacles between the devices hindering the radio signal transmission: walls, inserted ﬂoors, large objects located within the room.

The device developed only for indoor use.
Check the Jeweller signal strength at the installation point. With a signal level of one or zero divisions, we do not guarantee the stable operation of the security system. Move the device: even displacing it through 20 centimeters can signiﬁcantly improve the signal strength. If the detector still has a low or unstable signal level after moving, use a radio signal range extender.

The detector is located either inside or outside of the door case.
When installing the detector in the perpendicular planes (e.g. inside a door frame), use the small magnet. The distance between the magnet and detector should not exceed 1 cm.

When positioning the parts of DoorProtect in the same plane, use the big magnet. Its actuation threshold — 2 cm.
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 body. If necessary, the detector may be positioned horizontally.

Detector installation

Before installing the detector, make sure that you have chosen the optimal installation spot and that it complies with the terms of this manual.

In order to install the detector:

Remove the SmartBracket mounting panel from the detector by sliding it down.

Temporarily ﬁx the detector mounting panel to the selected installation spot using double-sided tape.
Double-sided tape is needed to secure the device only during testing upon installation. Do not use double-sided tape as a permanent ﬁxation—the detector or magnet may unstick and drop. Dropping may cause false alarms or damage the device. And if someone tries to tear the device off the surface, the tamper alarm will not trigger while the detector is secured with tape.
Fix the detector on the mounting plate. Once the detector is ﬁxed on the SmartBracket panel, the device LED indicator will ﬂash. It is a signal indicating that the tamper on the detector is closed.
If the LED indicator is not activated during installing the detector on SmartBracket, check the tamper status in the Ajax app, the integrity of the fastening, and the tightness of the detector ﬁxation on the panel.
Fix the magnet on the surface:
If a large magnet is used: remove the SmartBracket mounting panel from the magnet and ﬁx the panel on the surface with double-sided tape. Install the magnet on the panel.If a small magnet is used: ﬁx the magnet on the surface with double-sided tape.

Run Jeweller Signal Strength Test. The recommended signal strength is 2 or 3 bars. One bar or lower does not guarantee stable operation of the security system. In this case, try moving the device: a difference of even 20 cm can greatly improve signal quality. Use the radio signal range extender if the detector has low or unstable signal strength after changing the installation spot.
Run Detection Zone Test. To check the detector operation, open and close the window or door where the device is installed several times. If the detector doesn’t respond in 5 out of 5 cases during the test, try to change the installation spot or method. The magnet may be too far from the detector.
Run Signal Attenuation Test. During the test, the signal strength is artiﬁcially reduced and increased to simulate different conditions at the installation location. If the installation spot is chosen correctly, the detector will have a stable signal strength of 2-3 bars.

If the tests are passed successfully, secure the detector and magnet with bundled screws.
- To mount the detector: remove it from the SmartBracket mounting panel. Then ﬁx the SmartBracket panel with bundled screws. Install the detector on the panel.
- To mount a large magnet: remove it from the SmartBracket mounting panel. Then ﬁx the SmartBracket panel with bundled screws. Install the magnet on the panel.
- To mount a small magnet: remove the front panel using a plectrum or plastic card. Fix the part with magnets on the surface; use the bundled screws for this. Then install the front panel on its place.
- If uses screwdrivers, set the speed to the minimum so as not to damage the SmartBracket mounting panel during installation. When using other fasteners, make sure they do not damage or deform the panel. To make it easier for you to mount the detector or magnet, you can pre-drill the screw holes while the mount is still secured with double-sided tape.

Do not install the detector

outside the premises (outdoors);
nearby any metal objects or mirrors causing attenuation or interference of the signal;
inside any premises with the temperature and humidity beyond the permissible limits;

closer than 1 m to the hub.

Connecting a Third-Party Wired Detector
A wired detector with the NC contact type can be connected to DoorProtect using the outside-mounted terminal clamp.

We recommend to install a wired 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 a notiﬁcation.

Detector Maintenance and Battery Replacement

Check the operational capability of the DoorProtect 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 any substances containing alcohol, acetone, gasoline and other active solvents for cleaning the detector.
The battery lifetime depends on battery quality, actuation frequency of the detector and ping interval of the detectors by the hub.

If the door opens 10 times a day and the ping interval is 60 seconds, then DoorProtect will operate up to 7 years from the pre-installed battery. Setting the ping interval of 12 seconds, you will reduce the battery life to 2 years.

How long Ajax devices operate on batteries, and what affects this
If the detector battery is discharged, you will receive a notiﬁcation, and the LED will smoothly light up and go out, if the detector or tamper is actuated.
