ARMER is the Minnesota state wide emergency radio system. The acronym stands for Allied Radio Matrix for Emergency Radio. ARMER is a fully digital, trunked radio system used for mobile, two-way communication between the command center and officers, fire fighters and other emergency personnel. The ARMER system was first introduced in the Twin Cities metropolitan area.
Currently (in 2011) the system is being rolled out to other areas in the state. For this purpose the state is divided in regions, each region having an organization that is responsible for rolling out the ARMER system in that region. The Central Minnesota Radio Board is responsible for rolling out ARMER in the counties that together form the central Minnesota region.
