Fire Resisting Cables
Fire Resistant Coaxial Cables
RG11 A/U FR
Application
Fire Resistant Coaxial 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
