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. This is particularly important for complex security systems where signal integrity across multiple zones is critical.

The twelve-conductor configuration offers exceptional versatility for sophisticated security systems, multi-zone installations, or applications requiring numerous circuits in a single cable run. This reduces the number of cables needed, simplifying installation and reducing labor costs. The 18 AWG gauge provides good balance between current-carrying capacity and flexibility for professio
