The talkgroups listed in the database as Norman Fire 1 - 7 are fireground channels. They are used to keep communications for individual incidents off of the main dispatch talkgroup. With seven fireground channels, seven distinct incidents could be working simultaneously, each having its own channel. I don't think that I would want to be anywhere near the city if all seven were ever needed. Each station does not have its own talkgroup: Station 8 is dispatched on the main dispatch talkgroup along with the others and is assigned a fireground talkgroup, if necessary, along with the other responding units, from one of the existing seven.
