All Charleston County fire departments are dispatched on the main County Fire Dispatch talkgroup. This includes City of Charleston FD, North Charleston FD, Mt. Pleasant FD, and all other county fire departments, including those in municipalities and unincorporated areas. Fire Departments are also dispatched simultaneously on their unique Ops talkgroup. Dispatching is done via a computerized voice dispatch system. The dispatch narrative includes an assignment to a County Incident Channel, which are listed in a separate talkgroup group. The most common Fire Incident channel is Incident Channel 4. Ops A and Ops B channels are typically used more for admin purposes.
