Zero Halogen, Low
Smoke (OHLS®) coaxial cable for visual safety
systems.
Fire resistant 75Ω Coax
similar to RG59. Ideal 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 Firetuf Coaxial is ideal
for use in public, commercial and industrial
environments.
