Belden Inc. 88777 0021000 Audio Control Cable 22 Awg

Product Description

The BELDEN INC. 88777 0021000 is a 22 AWG stranded, shielded audio control and instrumentation cable designed for signal transmission in security, audio, and instrumentation applications. Built to PLE (plenum-rated) construction standards, this cable is suited for runs through air-handling spaces where fire and smoke performance requirements apply. The stranded conductor construction provides flexibility during installation, and the shielding helps reject electromagnetic interference that can degrade low-level audio and control signals. Licensed electricians and low-voltage technicians are the primary installers of this product.

This cable is used in commercial and residential installations where audio control signals, instrumentation data, or security system wiring must pass through plenum air spaces such as dropped ceilings or raised floors. Its plenum rating makes it appropriate for projects governed by local building codes that restrict the use of non-plenum cable in air-handling spaces. Typical applications include intercom systems, access control wiring, background audio distribution, and instrumentation signal runs.

Key Features

• 22 AWG stranded conductors for flexible routing in tight or complex pathways
• Overall shielding for rejection of electromagnetic and radio frequency interference
• PLE plenum-rated jacket construction meets fire and smoke spread requirements for air-handling spaces
• Suitable for audio control, instrumentation, and security signal applications
• Sold individually as a single unit (EA)

Compatibility

Designed as an OEM-style replacement and general-purpose cable for audio control, instrumentation, and security system wiring projects requiring 22 AWG stranded shielded plenum-rated cable.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements for plenum-rated wiring. De-energize all circuits before terminating or splicing. Avoid sharp bends that exceed the cable minimum bend radius, as this can damage the shield or conductors. Verify local code requirements for plenum cable use before beginning the rough-in.
