West Penn Wire 25292BBL1000 Plenum Audio Cable

Product Description

The WEST PENN WIRE 25292BBL1000 is a 1-pair, 20 AWG stranded shielded plenum-rated audio cable designed for low-voltage signal distribution in commercial and institutional installations. The plenum rating makes it suitable for routing through air-handling spaces without the need for conduit in many jurisdictions. Shielding reduces electromagnetic interference, maintaining signal integrity across longer cable runs. This cable is sold per foot or per reel unit as configured at the point of purchase, and is installed by licensed low-voltage technicians and audio-visual contractors.

This cable is commonly used in commercial audio distribution systems, public address installations, intercom wiring, and background music systems. Its plenum-rated jacket meets fire and smoke propagation requirements for installation in environmental air spaces such as dropped ceiling plenums and raised-floor return-air zones. It is a standard choice for AV contractors and systems integrators working in office buildings, schools, healthcare facilities, and retail environments where plenum code compliance is required.

Key Features

• 1-pair, 20 AWG stranded conductors for flexible routing and reliable low-voltage signal transmission
• Shielded construction reduces EMI and RFI interference on audio signal runs
• Plenum-rated jacket meets fire and smoke requirements for air-handling space installations
• Stranded conductor construction improves flexibility during pull-through installations
• Suitable for professional audio, intercom, and background music wiring applications

Compatibility

Designed as a plenum-rated audio cable suitable for use in commercial low-voltage audio distribution, public address, and intercom systems requiring shielded 1-pair 20 AWG plenum cable.

Installation Notes

Installation should be performed by a licensed low-voltage or electrical contractor in accordance with applicable NEC Article 800 and local AHJ requirements. De-energize all connected equipment before terminating or splicing the cable. Maintain minimum bend radius during pulls to avoid damaging the shield or jacket. Verify plenum rating compliance with local code before installing in air-handling spaces.
