Simplex 2084-9003 Firefighter Phone AssemblyFirefighter telephone systems provide two way communications for facilities where radio communications may not be available or are unreliable. They are typically used during active firefighting conditions, during a fire alarm investigation, or during fire alarm system inspection and test. Operation requires a dedicated two wire circuit, typically using twisted, shielded pair wiring (TSP) to minimize electrical noise pickup from adjacent wiring.
