With OS Malevich 2.9 update, temporary 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 hub, or is defective.
To deactivate a device, go to its settings (Ajax app → Devices tab → select the device you need → Settings → Temporary Deactivation).
Tamper is a miniature button on the device board. It is released when the lid is opened as well as a result of an attempt to unfasten and/or lift the device from the surface, which initiates an event.
When the tamper is released, the Hub sends push notifications and SMS messages (if this type of notification is enabled) to all users of the security system and also communicates the event to the central monitoring station of the security company.
If the tamper is released, Ajax applications display the Open status in the Lid field of the device menu. In addition, a malfunction badge appears on the device icon.
Each device measures temperature independently with an internal sensor. Air circulation in a room, along with other factors, may cause slight inconsistencies in the measured temperatures. The temperature displayed in the Rooms tab is an average of all the detectors in a given room and can differ from environmental temperature by 2-4°C.
The QR-code is located next to the power button, under the cover on the rear side of the detector. You can also find the QR-code on the box the device came in.
The maximum distance between the Hub and the detector can reach up to 2000 meters in open spaces. Walls, ceilings and other structures between Hub and the detector, reduce the range of action several times. In this case, the maximum distance depends on the material, thickness, and configuration of the walls.
Detector and smoke chamber test. As a result, the Ajax application will receive a notification specifying whether the detector and its smoke chamber are OK and whether cleaning is required.
The test allows you to determine the status of the detector and its chamber at the current moment in time. The detector automatically performs self-testing once a day. Therefore, in any case, the user will be notified of a malfunction.
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.
By default, the hub is set to ping detectors every 36 seconds and to signal an alert after 30 undelivered pings. Under these settings, it will take about 18 minutes for the system to recognize a communication failure. You can adjust these settings in the hub settings → Jeweller.
The loop (zone) number is required to add a guarded facility to the CMS along with descriptions of all devices connected to the hub.
The loop (zone) number is available in the settings after activating the group mode in the Ajax application:
Having selected a group, you will see a list of its devices. Each device has a Device No. (or DeviceIndex in Ajax PRO Desktop) that corresponds to the loop (zone) number. A number is assigned when a device is attached to the Hub. The first added device has the first loop (zone) number.
After a device or a detector is removed, its number will be assigned to the next added device. However, the numbering of other devices will not change.
In the Ajax app, select the«Devices» tab . Information about the firmware version and device ID is located at the very bottom of the tab with the device parameters.
Go to the Device tab, select the device you want to check.
