Dont forget about the new Control 5Control 1 is Dispatch
Control 2 is normal Tac channel for fires
Control 3 is usually used as tac for non fire incidents (HazMat, accidents, water rescue, etc), training, and as interop with county fire departments
Control 6 is the command channel at large incidents, and also for not tactical traffic so they don't tie up one of the other channels
The database freq and tones are correct.
