Fire resistant RG6 A/U Coaxial cables

RG6 A/U FR

Fire resistant RG6 A/U Coaxial cables

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.
