Type CMP, c(UL) PCC Multi Paired Overall Foil Shielded Plenum Telephone Cable

An overall foil shield helps reduce interference affecting all of the pairs within the cable.

Instead of shielding each pair separately, the foil surrounds the complete group of conductors. This can provide a practical balance of signal protection, cable size and cost for communication, alarm, intercom and control circuits where common external interference is a concern.

Yes, this cable is listed for power-limited applications that include fire and burglar alarm systems.

The page also identifies uses such as energy management, computer interfaces, intercom systems and remote control equipment. The final cable selection should still match the system requirements, applicable code and project specifications.

This cable is available in several pair counts to accommodate different circuit requirements.

The listed constructions include 1, 2, 3, 4 and 6-pair options, with 22 AWG and 24 AWG sizes depending on the specific item. That allows the cable to support applications ranging from simple point-to-point connections to systems requiring multiple signal pairs in one jacket.

Yes. Its CMP rating is intended for use in plenum air spaces where plenum-rated cable is required.

The listed construction is designed to meet low-smoke and flame-spread requirements and is approved under UL standards for CMP communication cable. Local code and project specifications should always be checked before installation.

The main difference is conductor size, which can affect resistance, cable diameter and suitability for a given circuit.

A 22 AWG conductor is larger than 24 AWG and generally has lower electrical resistance over the same distance. The correct choice depends on run length, signal requirements, connected equipment and the project specification.
