Fire Resistant Cable 

Fire Resistant Cable

Fire resistant RG59 B/U Coaxial cables

RG59 B/U FR

Fire resistant RG59 B/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.

STANDARDS
Basic design to MIL-C-17

VOLTAGE RATING
60V
