How to Select CM, CMR and CMP Cable?
CMR: The 'R' in CMR is for 'Riser'. Riser type cables are engineered to prevent the spread of fire from floor to floor and are suitable for vertical shaft applications.
CMP: The 'P' in CMP is for Plenum. Cables meeting type CMP requirements are suitable for installation in ducts and plenums without the use of conduit. These cables are designed for fire resistance and low-smoke and toxin producing characteristics.
CMX: The 'X' in CMX is for Outside Plant. Cables meeting type CMX requirements are suitable for installation in outdoor applications where exposed to the elements.
CM/CMH/CMG: CM is used for general building wiring such as residential house. CM cables are used in areas other than plenums and risers.
A plenum space is the open area above the drop ceiling or below the floor that is used for air circulation in buildings. This could be a problem if there is ever a fire. Using non-plenum cables in a plenum space can spread fire and toxic smoke throughout a building. Plenum cable uses a flame-retardant jacket that is made of special plastics to prevent the release of harmful smoke. Plenum cable is mostly used in commercial applications such as schools and hospital buildings that house a large population of people. It also is required in most multi-floor business buildings with large plenum space areas.
