Installation Notes

This riser-rated cable is designed for vertical installations between floors in non-plenum spaces, such as riser shafts, elevator shafts, and vertical cable runs in walls. The CMR rating ensures the cable meets fire safety requirements for these applications.

The aluminum mylar shielding provides protection against electromagnetic interference, making it ideal for installations near electrical equipment or in electrically noisy environments. This is particularly important for CCTV camera installations and security systems where signal integrity is critical.

The 18/2 configuration with shielding is perfect for security cameras, basic alarm zones, door contacts, motion detectors, and power-limited circuits requiring two conductors with interference protection. The compact 4.19mm diameter makes it easy to route through conduits and tight spaces.

Always consult NEC Article 725, 760, and 800 requirements and local building codes before installation.
