Fire Resisting Cables
Fire Resistant Coaxial Cables
Fire resistant RG6 A/U Coaxial cables
RG6 A/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.
Standards
Basic design to MIL-C-17
