Wireless bi-directional outdoor curtain motion detector with an adjustable detection range
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.

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:

.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.
To check that the device is operating correctly, carry out the detection area and signal strength tests.
The detection area tests allow you to determine the distance at which the detector will detect alarms and protect it from false triggering. In test mode, the LED indicator lights up continuously, switching off during the alarm. In order to determine the detection area, use the device’s LED indicator as a guide.
The Jeweller signal strength test allows to determine signal strength and stability in the potential installation place of the device.
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 firmware version can be found in the device states in the Ajax app.
