Maryland's new interoperable public safety radio system, known as Maryland FiRST, has been a great success in providing mission critical, interoperable, voice communications to Maryland's first responders. With over 75% of the system built out, there are over 22,407 first responders on the system as primary users with another 44,140 as interoperable users representing 66 State agencies, local governments and Federal agencies.
Primary Users - A primary user agency is approved by the Radio Control Board and utilizes Maryland FiRST as their primary radio communications system to conduct daily operations. A primary user agency can be any Maryland State, county or local public safety agency.
Interoperability Users - An interoperablility user agency is approved by the Radio Control Board and utilizes Maryland FiRST for interoperable communications during special events, emergencies, mutual aid and joint operation. They are authorized to use MD Call/TAC or MD Marine Call/TAC talkgroups and to enter into talkgroup sharing agreements with primary user agencies. Interoperable user agencies can be federal, neighboring states, county or local public safety agencies.
