1802UCMRRG · 18 AWG Commercial Security & Control Cable (2, 3, 4 & 6 Conductor, Shielded & Unshielded, Riser & Plenum)

18 AWG multi-conductor commercial security and alarm control cable featuring 7-strand bare copper conductors, color-coded insulation, an internal rip cord, and a protective jacket. Available in 2, 3, 4, and 6-conductor configurations, as well as unshielded and overall aluminum-mylar foil shielded (with a 24 AWG tinned copper drain wire) options to defend against signal interference. Offered in Riser-rated PVC (CMR/CL2R/CL3R/FPLR) and Plenum-rated low-smoke copolymer/PVC (CMP/CL2P/CL3P/FPLP) constructions for vertical risers or environmental air-handling plenum spaces. Designed for high-reliability low-voltage installations, including security systems, sound and audio systems, intercoms, fire alarm signaling, and power-limited control circuits. Manufactured to meet current NEC guidelines with descending sequential footage markings for easier tracking and installation.
