Fire Resisting Cable

Fire Resisting Cables

Fire Resistant RS 485 Databus Cables

APPLICATION

Fire Resistant RS 485 Databus Cables are designed for RS 485 data connections where continued functionality

is required during a fire situation. This cable combines low capacitance insulation with one of the highest levels

of screening to provide high speed, interference free, data transmission where continued functionality is

required during a fire situation.
