Wireless magnetic opening detector
The identifier (ID) is the serial number of the device. It is located under the QR code on the body, board, and packaging of the device.
ID at the bottom of the box
ID under the lid
The ID can also be found in the device states in the Ajax app.
menu.The alarm LED indication can be disabled in the device settings. The option is supported by all Ajax intrusion detectors with the following firmware versions:
| Detector model | Firmware version |
| DoorProtect Jeweller DoorProtect Plus Jeweller GlassProtect Jeweller MotionProtect Jeweller MotionProtect Plus Jeweller CombiProtect Jeweller MotionProtect Outdoor Jeweller |
5.55.0.0 and later |
| MotionProtect Curtain Jeweller | 6.53.1.1 and later |
| All other intrusion detectors | all firmware versions |
With OS Malevich 2.9 update, permanent deactivation of devices without removing them from the system has become available.
Deactivation may be necessary if the device is incorrectly installed or configured, loses connection with the hub, or has failed.
To deactivate a device, in the Ajax app:
menu.
.Tamper is a miniature button on the device board. It reports an alarm in case of opening the device enclosure, removing the device from the mounting panel, or detaching it from the surface.
The tamper status is displayed in Ajax apps, in the Enclosure section in the states of each device. When the body status is Open, a fault symbol appears on the device icon.
The temperature is measured by sensors inside each detector, which can heat up differently due to the circulation of air currents in the room. The value may differ from the ambient temperature by 2°C.
The temperature displayed in the Rooms 
tab is the average of these temperatures for each detector assigned to the room. The temperature data of the street detectors is not taken into account.
On some devices, the QR code is located under the SmartBracket mounting panel. To add a detector, remove the mounting panel and scan the QR code.
Also, the QR code is located on the packaging and the device board inside the body.
The maximum distance between the hub and the device can reach 2,000 meters in an open space.
Walls, ceilings, and other structures that interfere with the radio signal to get through can significantly reduce the range. In this case, maximum distance mainly depends on the structures’ material, thickness, and arrangement.
You can expand the coverage area of Ajax security systems with the help of radio signal range extenders
Yes, you can connect an infrared barrier to the opening detectors:
Optimal dust, moisture, and temperature conditions should be adhered to. The length of the wire loop should not exceed 5 meters.
No, you can not connect a wired siren to the external contact of opening detectors:
The external terminal is a digital input, not a power output.
The third-party wired siren can be connected to Relay Jeweller and MultiRelay Fibra.
Magnets must be installed parallel to the main unit, on the right side. There is a special mark on the detector that shows where magnet should be placed. Small magnet works at a distance up to 1 cm from the detector, while big one – up to 2 cm.
The magnet is too far away from the reed switch. Re-install the magnet closer to the sensor or use a larger magnet. Magnets should be installed parallel to the main unit, on the right side.
To check that the device is operating correctly, carry out the detection area and signal strength tests.
The detection zone test helps to determine at what distance the detector will detect motion. To determine the detection zone, monitor the LED indicator of the device: during the test, it lights constantly, and turns off when motion is detected. At the same time, a pop-up window appears in the app informing you that the device has detected motion.
In-app notifications are available for hubs with firmware version Malevich 2.26 and later and in apps of such versions and later:
The Jeweller signal strength test allows to determine signal strength and stability in the potential installation place of the device.
The detector is designed to be installed indoors only. Installing the motion detector outdoors can cause false alarms as well as failure of the device. In case of failure to comply with temperature conditions, the battery life may be significantly reduced.
The detector is set to Always Active. If you don’t need this level of security, you can turn it off in the detector settings.
Always active mode is required for round-the-clock protection of an object, regardless of security system status (armed or disarmed).
Yes, you can. The detector is compatible with wired and wireless systems using Ajax ocBridge Plus or Ajax uartBridge.
By default, the hub is set to a hub–detector ping interval of 36 seconds and 30 undeliverable data packets to consider the device lost. With these settings, the hub will detect the loss of the detector in 18 minutes.
To reduce this time, go to the hub settings in the Jeweller section and change the settings. The minimum time for detecting loss of connection with the device is 36 seconds (3 polls of 12 seconds each).
The time before raising the alarm by the communication loss between hub and device is calculated with the following formula:
Detector Ping Interval × Number of missed pings to determine connection failure
Note that with the minimum ping interval, short-term interference can lead to loss of connection with the device. Therefore, set the minimum values only if it is critically important to promptly inform about events in the system.
The loop (zone) number is required to describe all devices connected to the hub when adding a protected facility to the security company monitoring station.
The number is assigned when adding a device to the hub. The first added device has the first loop (zone) number. After removing the device from the system, its number becomes available. This number can be assigned to the next device to be added to the system.
The loop (zone) number is available in the states of each device in the Ajax app:
The firmware version can be found in the device states in the Ajax app.
menu.
Delay When Entering/Leaving is the time the user has to disarm the security system after entering/leaving the protected area.
The function can be configured for all security detectors and sirens of the Ajax security system. Also, the delay can be separately configured for Night mode.
When the Always active mode is enabled, the detector is constantly armed and detects movement, activating an alarm.
To enable the Always Active mode, in the Ajax app:
tab..
Go to the Devices tab , select the device you want to check.
