Description & Applications:

The Air Plenum space is the area through which environmental air is transported in a building. Examples of this include the space above a suspended ceiling or below a raised floor that does not have closed air ducts for the HVAC system to move air. Most often this space is used as the air return.

Plenum coax cable is primarily used in commercial and institutional buildings as part of a structured cabling system, computer network cabling or other building wiring. 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.
