Genesis Cable 22151109 18/4 Stranded Shielded Cmr Cable 1000 Ft

Product Description

The GENESIS CABLE 22151109 is an 18 AWG, 4-conductor stranded shielded security cable rated CMR (Communications Multipurpose Cable, Riser) and supplied in a 1000-foot box. The gray PVC jacket and foil shield are suited for low-voltage security, access control, and alarm system wiring in riser applications where flame spread must be limited. Licensed alarm and low-voltage technicians install this cable in new construction and retrofit projects where a riser-rated, shielded run is required by code or system design.

This cable is used in commercial and residential security system installations including intrusion detection panels, access control readers, fire alarm auxiliary circuits, and other 4-conductor low-voltage signal runs. The CMR rating qualifies it for vertical runs between floors in non-plenum spaces. The foil shield helps reduce electromagnetic interference on signal lines, making it a common choice where cable runs pass near electrical conduit or HVAC equipment.

Key Features

• 18 AWG stranded conductors for flexibility during pull and termination
• 4-conductor configuration supports common security and access control wiring layouts
• Foil shield reduces EMI and RFI interference on signal lines
• CMR riser rating meets NEC Article 800 requirements for vertical floor-to-floor runs
• Gray jacket for standard in-wall and conduit identification
• 1000-foot box pull for full-system or multi-zone installations

Compatibility

Designed for use with low-voltage security, alarm, and access control systems requiring a 4-conductor stranded shielded riser-rated cable. Verify panel and device terminal specifications before installation.

Installation Notes

Installation should be performed by a licensed low-voltage or alarm technician in accordance with NEC Article 800 and applicable local codes. De-energize all connected panels and devices before terminating conductors. Maintain minimum bend radius during pulls to avoid damaging the foil shield or conductor insulation. Do not route CMR-rated cable in plenum air-handling spaces — a CMP-rated cable is required for those environments.
