Plenum coax cable is specifically designed for use in air plenum spaces, which are areas in a building where environmental air is transported, such as above a suspended ceiling or below a raised floor. These spaces are commonly used as air returns when there are no closed air ducts for the HVAC system to circulate air. When installing infrastructure like a coaxial cable in these plenum spaces, it is crucial to use cables with specialized plenum-rated insulation. Plenum coax cables meet stringent fire safety standards, minimizing flame spread and toxic fume emissions in case of a fire, ensuring both compliance and safety in such critical areas.
Remee Plenum Coax Cables carry a CMP rating, allowing them to be used in air plenums within buildings.
Plenum coax cable is primarily used in commercial and institutional buildings for CCTV security, CATV and other video applications. Plenum Coax allows building owners and facility managers to run coax throughout their buildings while meeting local fire and building codes.
The Plenum coax cable rating (CMP) assures the user of flame retardancy and toxicity levels as defined by specific flame tests. CMP is the plenum rating for Communications cables, established by the NEC code.
Although local building codes dictate exactly what is required in a local area, the National Fire Protection Association (NFPA) provides a recommendation on a national basis. For Plenum rated cables, this falls under NFPA-262. The UL equivalent is the UL-910 standard, which is made up of two primary tests, cable burn properties and smoke density. The Canadian Electrical Code (CEC) designation meets the FT-6 horizontal flame and smoke test. The U.S. version of this test is known as the NFPA 262 “Steiner Tunnel” Flame Test (formerly UL 910), which measures flame spread and smoke generation in a simulated air handling plenum.
