Description 
 
Firefighter 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. Depending on 
the master control, up to 6 remote phones and the master can 
be in simultaneous use. Additional information can be found 
in Installation Instructions 579-226 and on data sheet 
S4100-0034 which describes 4100U Master phone control 
operation.
