5.5.2 Zone grouping
On the Zone grouping page, zone groups can be created. A zone group is a group of zones
that, for example, go to the same geographical area.
Configuration example
A small airport with four zones: Departure1, Departure2, Arrival1 and Arrival2:
– The zones Departure1 and Departure2 contain loudspeaker lines that go to departure
hall1 and departure hall2 respectively.
– The zones Arrival1 and Arrival2 contain loudspeaker lines that go to arrival hall1 and
arrival hall2 respectively.
Then, a zone group can be created called "Departure Halls" to group the zones that go to the
departure halls and a zone group called "Arrival Halls" to group the zones that go to the arrival
halls.
