The GENESIS CABLE 46021004 is an 18 AWG 2-conductor solid plenum-rated fire alarm cable supplied on a 1000-foot roll in red jacket. Rated FPLP (Fire Power Limited Plenum), this cable meets the requirements for installation in air-handling spaces and plenum ceilings where building codes restrict combustible materials. The solid conductor construction supports reliable signal transmission in addressable and conventional fire alarm circuits. Fire alarm technicians and low-voltage contractors install this cable as part of initiating device circuits, notification appliance circuits, and control wiring in commercial and residential fire protection systems.
This cable is suited for plenum-rated fire alarm installations in commercial buildings, schools, healthcare facilities, and multi-family residential construction. The red jacket provides visual identification consistent with fire alarm system wiring conventions. It is commonly pulled through plenum ceiling spaces, conduit, and cable trays where smoke and flame spread ratings are required by the International Fire Code and NFPA 72. The 1000-foot roll length supports large-run installations with minimal splicing.
Designed as an OEM-style plenum fire alarm cable suitable for use in FPLP-rated fire alarm system wiring applications per NFPA 72 and local fire codes.
Installation should be performed by a licensed fire alarm technician or low-voltage contractor in compliance with NFPA 72, NFPA 70 (NEC Article 760), and applicable local codes. De-energize the fire alarm control panel and follow lockout procedures before terminating or splicing conductors. Plenum-rated cable must be used in any air-handling space as required by the authority having jurisdiction. Do not exceed the cable manufacturer's minimum bend radius during pull-through to avoid conductor damage.
