Shielded conductors are commonly used in security and alarm systems to connect keypads, sounders, strobes, intercoms, and control panels. They also support audio, CCTV, and data communication installations where shielding helps preserve signal quality along cable runs.

Choose conductor gauge based on the system’s power and distance requirements, with 18 AWG and 22 AWG options available, and choose the conductor count to match the number of circuits or signals in the run. Select a riser or plenum jacket rating according to the installation space, then choose a 500-foot or 1,000-foot cable length that fits the project while limiting splices.

Riser-rated shielded conductors, such as CL3R cable, are designed for vertical runs between building floors, while plenum-rated shielded conductors, such as CL3P cable, are intended for air-handling spaces where the cable jacket must meet more demanding fire and smoke requirements. Choose the rating that matches the pathway and local code, and use the shielding to help limit electromagnetic interference in security, audio, and control circuits.

Choose shielded twisted-conductor cable when a project needs multiple individual conductors for security and alarm devices, control panels, keypads, sounders or strobes, intercoms, or audio. Choose shielded coaxial cable for CCTV, audio, video, or data communications that use a coaxial connection, particularly when dual shielding can help support signal retention.
