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 unshielded construction makes this cable ideal for installations where electromagnetic interference is not a concern, providing a cost-effective solution for basic alarm circuits. The 3-conductor configuration is perfect for security zones, door contacts, motion detectors, and other devices requiring three wires. The convenient rip cord allows for quick jacket removal during termination.
Always consult NEC Article 725, 760, and 800 requirements and local building codes before installation.
