About Twin State Mutual Aid Fire Association
Twin State Fire is the dispatch center and coordinating agency for fire and emergency medical services operations in 24 towns in Grafton and Coos Counties, New Hampshire, and Orange County and Caledonia County in Vermont.
Most of the departments in the Twin State system rely heavily on volunteer fire and EMS personnel, although positions are staffed by full-time members.
Some departments like Littleton, NH have a mix of full-time and on-call firefighters, while other departments like Landaff are entirely volunteer. Private and municipal ambulance services are used in the service area.
All radio dispatches use the frequency 154.4000 under the call-sign KSI-676.
