Installation Notes
This plenum-rated cable is designed for installation in air handling spaces, drop ceilings, and HVAC plenums where low-smoke, fire-resistant materials are required by code. The CMP rating is the highest fire safety rating for communications cables, making it suitable for the most demanding commercial installations.
The aluminum mylar shielding provides excellent protection against electromagnetic interference, ideal for installations near electrical equipment or in electrically noisy environments. The six-conductor configuration offers maximum versatility for complex security systems, multi-zone installations, or applications requiring multiple circuits in a single cable run.
The 18 AWG gauge provides a good balance between flexibility, current-carrying capacity, and cost-effectiveness for most commercial security applications. The low-smoke PVC jacket and insulation ensure compliance with plenum fire safety requirements while maintaining flexibility for installation in tight spaces.
Always consult NEC Article 725, 760, and 800 requirements and local building codes before installation.
