Belden 6521FE 8771000 1 000' 3‑Conductor 22 AWG Shielded Plenum Security Audio Cable, Natural

Optimize audio paths for security, surveillance, and facility monitoring with the Belden 6521FE plenum audio cable. This plenum audio cable combines a shielded 3-conductor 22 AWG design with a plenum-rated jacket to deliver clear, interference-resistant audio where building codes require low-smoke, low-flame materials. The 1,000' spool lets integrators run long continuous lengths with fewer splices, accelerating deployments for CCTV, access control, paging, and environmental monitoring systems.

Engineered for professional installations, the cable’s shielding minimizes electromagnetic interference from nearby power and data runs, preserving intelligibility for alarms and two-way audio. The natural-colored jacket provides a subtle appearance in ceiling plenums and conduit while remaining rugged enough for repeated handling during installation. Belden’s construction and quality control mean predictable impedance and long-term reliability across distributed security and AV networks.

Specify this cable for projects that demand code-compliant plenum performance and high-quality audio signal integrity. Order the Belden 6521FE 1,000' plenum audio cable to streamline your next security or surveillance installation.
