Belden 6401FE 8771000 20/3 Plenum Security and Audio Cable, 1000', Natural

Ensure consistent, interference-free audio and security signals in plenum spaces with the Belden plenum audio cable. Designed for mission-critical environments, this 20/3 plenum-rated cable provides reliable performance for intercoms, PA systems, access control, surveillance and monitoring installations. The cable’s 3 stranded 20 AWG conductors deliver balanced audio and control pathways while 100% shielding (Beldfoil + drain) minimizes electromagnetic interference and crosstalk that can degrade surveillance and security feeds.

Built for commercial deployments, the 1000' reel reduces the need for splices and keeps installation time and labor costs down. The flame-retardant plenum jacket meets air-handling space requirements and the integrated ripcord speeds jacket removal for quick terminations. With a transparent jacket for easy conductor identification and a 10-year limited warranty, this Belden plenum audio cable is a dependable choice for integrators managing audio, monitoring, and security systems. Ideal for camera audio, intercom lines, and emergency communications — add this cable to your next installation to improve signal integrity and system reliability.
