Wirepath NST-222-SH-R-1K-GRY Plenum Audio Cable Gray

Product Description

The WIREPATH NST-222-SH-R-1K-GRY is a shielded, plenum-rated audio cable intended for low-voltage signal distribution in commercial and residential structured wiring installations. Rated for plenum air-handling spaces, this cable meets the stricter fire and smoke requirements demanded by building codes in ceiling and duct plenum environments. The 22 AWG conductors support clean signal transmission over extended runs, and the foil shield reduces electromagnetic interference common in multi-cable conduit or above-ceiling environments. Low-voltage installers, AV integrators, and structured cabling technicians are the primary trades working with this product.

This cable is suited for audio distribution, intercom wiring, and low-voltage signal runs in commercial offices, multi-family residential buildings, schools, and hospitality installations. Its plenum rating makes it the correct choice wherever cable must pass through HVAC air-handling plenums without conduit. The 1,000-foot box reel format supports larger project pulls and reduces field splicing. Gray jacket color aids in cable identification in mixed-cable trays and above-ceiling runs.

Key Features

• Plenum-rated jacket meets CMP fire and smoke requirements for air-handling spaces
• 22 AWG conductors support long signal runs with low resistance
• Foil shield reduces EMI and RFI interference on audio signal pairs
• 1,000-foot pull box format reduces splices and speeds up larger installations
• Gray jacket for straightforward cable identification in structured wiring environments

Compatibility

Designed as a plenum-rated, shielded audio cable for low-voltage signal distribution applications in commercial and residential structured wiring systems.

Installation Notes

Installation should be performed by a licensed low-voltage technician or structured cabling installer in accordance with NFPA 90A and local AHJ requirements for plenum cable routing. De-energize any connected audio or signal equipment before terminating conductors. Avoid sharp bends that exceed the cable minimum bend radius, and maintain physical separation from high-voltage power conductors per NEC Article 800 guidelines.
