MPP is an abbreviation for multi-purpose plenum cable, a communication cable rated for installation in plenum air-handling spaces, with strict fire and smoke performance.
MPP designates multi-purpose plenum cable, the highest fire-performance class within the multi-purpose communication cable family. Plenum-rated cable is built to meet strict requirements for low flame spread and low smoke generation, because it is installed in plenum spaces, the air-handling areas of a building where fire and smoke could spread rapidly through the ventilation system.
Because plenum spaces carry circulating air, cable installed there must limit the contribution of flame and smoke in a fire, which is why MPP cable uses specially formulated materials. This makes plenum cable suitable for the most demanding installation locations among communication cable classes.
In commercial and industrial facilities, multi-purpose plenum cable supports communication and signal applications routed through air-handling spaces where the highest fire performance is required. Applying plenum-rated cable in these locations is part of meeting safety requirements and building a compliant low-voltage system.
Because plenum spaces share air with occupied areas, the strict flame and smoke limits behind the plenum rating are a safety matter, which is why multi-purpose plenum cable uses specially formulated materials suited to the most demanding installation locations.
At Windy City Wire, the focus on low-voltage communication cable includes plenum-rated classes like multi-purpose plenum cable. Supplying cable with the appropriate fire ratings helps commercial facilities apply the right product for air-handling spaces and other demanding locations.
