To manage the different devices in the easiest possible way, Ajax has a Group mode. This option allows grouping the different devices independently of their physical location. In this way, individual detectors or groups can be manually or programmed.
The maximum number of groups depends on the Hub model:
Hub model. Number of Groups
Hub 9
Hub Plus. 25
Hub 2. 9
Hub 2 Plus. 25
The Group mode is different from the rooms, the rooms are created to organize the devices to report where the alarm happens. And it is also different from the Night mode which is used for night protection and therefore has different settings and shortcuts.
