Genesis Cable 21145501 18/2 Stranded Riser Cable 500 Ft

Product Description

The GENESIS CABLE 21145501 is an 18 AWG 2-conductor stranded riser-rated security cable supplied in a 500-foot pull box. It is designed for in-wall and between-floor signal wiring in security, access control, and low-voltage alarm systems. The stranded conductor construction provides flexibility during pull-through installations in conduit or open plenum-adjacent runs. Riser (CMR) rating meets the fire-propagation requirements for vertical runs between floors in commercial and residential structures. Licensed security and low-voltage electricians are the primary installers of this cable type.

This cable is suited for residential and light commercial security system installations including intrusion detection panels, door and window contacts, motion sensors, and access control devices. The white jacket blends with standard interior trim and drywall finishes. The 500-foot box format supports medium to large installations without mid-run splices, reducing signal path resistance and labor time.

Key Features

• 18 AWG stranded conductors for flexible routing through walls and conduit
• 2-conductor configuration for standard security device wiring
• Riser (CMR) fire rating approved for vertical shaft and between-floor runs
• White PVC jacket for clean appearance in finished spaces
• 500-foot box format reduces splice points on larger jobs

Compatibility

Designed as an OEM-style replacement and standard-stock cable for low-voltage security and alarm wiring applications requiring 18 AWG 2-conductor riser-rated cable.

Installation Notes

Installation should be performed by a licensed low-voltage or security systems technician in accordance with NEC Article 725 requirements for Class 2 and Class 3 remote-control and signaling circuits. Verify that the riser rating is appropriate for the run path — plenum-rated cable is required in HVAC air-handling spaces. De-energize all connected panels and devices before terminating conductors. Avoid sharp bend radii that can damage stranded conductors and increase resistance at termination points.
