Fire Resisting Cable

Fire Resisting Cables

RG11 A/U FR

Fire Resistant Coaxial Cables
RG11 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
