Genesis Cable 21151109 18/4 Stranded Riser Cable 1000 Ft

Product Description

The GENESIS CABLE 21151109 is an 18 AWG, 4-conductor stranded riser-rated cable supplied on a 1000-foot box, finished in gray. Designed for low-voltage security and alarm system wiring, this cable meets riser (CMR) fire rating requirements, making it suitable for in-wall and between-floor vertical runs in commercial and residential structures. The stranded conductor construction offers flexibility during pull and termination, reducing wire fatigue in routing-heavy installations. Security installers and low-voltage technicians working on access control, intrusion detection, and fire alarm auxiliary wiring rely on this cable type for reliable signal transmission.

This cable is well suited for residential and light commercial security system installations where a riser-rated, multi-conductor cable is required. Typical applications include panel-to-device runs for alarm keypads, motion detectors, door contacts, and similar low-voltage security components. The 4-conductor configuration supports a range of standard wiring topologies used in modern security system layouts.

Key Features

• 18 AWG stranded conductors for flexibility and ease of termination
• 4-conductor configuration supports common security and alarm wiring schemes
• Riser (CMR) fire rating approved for vertical in-wall and floor-to-floor runs
• 1000-foot box quantity reduces mid-job resupply on larger installations
• Gray jacket finish for standard low-voltage security applications

Compatibility

Designed as an OEM-style stranded riser cable for low-voltage security, alarm, and access control system wiring in residential and commercial installations.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm technician in accordance with applicable local codes and NEC Article 800 requirements for communications and signaling cable. De-energize any connected control panels or devices before making terminations. Use appropriate cable staples or supports at required intervals per code, and avoid sharp bends that could damage the conductors or jacket. Do not use riser-rated cable in plenum air-handling spaces — a plenum-rated (CMP) cable is required in those environments.
