Detectors identify threats immediately: door opening, window breaking, or the presence of trespassers on the premises
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.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
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.
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).
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:
