Alarm groups:
If you have defined the external unit as a connected unit in your company locations, you must then create the alarm groups first. New alarm groups are created directly via the plus symbol. All changes to the alarm groups are also made in the "Alarm groups" settings.
Enter a name and assign the desired alarm types to the alarm group via the "Alarm types" field. For example, all "fire" alarm types from the various company locations.
If there are already existing alarm filters, you can assign the alarm group to these filters in the creation process. Otherwise you can also do that later.
In the last step, select a suitable alarm symbol and press "Create" to save your settings.
