Fire Resisting Cable

Fire Resisting Cables

Fire Resistant Coaxial Cables

Fire resistant RG59 B/U Coaxial cables

RG59 B/U FR

Application

The cables are designed for CCTV, security, smoke detection and evacuation monitoring applications, where

continued functionality is required during a fire situation. Due to the zero halogen low smoke construction,

this cable is ideal for use in public, commercial and industrial environments.
