Dispatch centers
By default, stations within 4 km of each other share their units. Stations farther apart stand alone. A dispatch center lets you decide.
How range works
Every building has a call radius of 4 km. Calls appear within 4 km of a building. A call that needs several services, such as a car fire that needs fire and police, only appears if the units are in range of each other.
Build a center
A Dispatch Center is free, and you can own one for every 10 buildings. It has no vehicles and no range of its own.
A dispatch center is a group, not a place. You choose which stations belong to it, at any distance. The units of every station in the group count for a call around any of those stations. A fire station and a police station on opposite sides of the city can answer car fires together. A station that is not in the group is out of range, even if it is next door.
Put a station in a group
New stations start with None. Open a station's panel and pick its dispatch center. The Build menu has a Dispatch center field at the top and remembers the last one you used, so new stations go straight into that group.
When you select a center, a dashed circle on the map shows where new calls can appear around each of its stations.
Pause new calls
A center's panel has a Pause new calls switch. Open calls carry on, but no new ones appear around the stations of that group. This is useful when you want to take a break in one part of the map.
Show call areas on the map closes the panel and draws the areas where the group's stations get calls.
Selling a center
Selling a center removes its stations from the group. The stations stay.
