Fire Resisting Cables
Fire resistant RG6 QUAD Coaxial cables
RG6 QUAD 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
