Genesis Cable 46025504 18/2 Solid Shielded Fire Alarm Cable 500 Ft

Product Description

The GENESIS CABLE 46025504 is an 18 AWG 2-conductor solid shielded fire alarm plenum cable supplied on a 500-foot reel. Built to serve life-safety systems, this cable carries signaling current between fire alarm control panels, initiating devices, and notification appliances. The solid conductors provide stable low-resistance connections in fixed-run installations, and the foil shield reduces interference from nearby electrical equipment. Plenum-rated construction meets stricter smoke and flame requirements for air-handling spaces, making it the appropriate choice when runs pass through return-air plenums or ducts without conduit.

This cable is used in commercial and residential fire alarm installations where a plenum-rated pathway is required by the local authority having jurisdiction. Typical applications include connecting smoke detectors, pull stations, horn-strobe devices, and other Class B or Class A initiating and notification circuits. The 500-foot reel quantity suits medium to large new-construction or renovation projects where significant footage is pulled in a single job phase. Installation is performed by licensed fire alarm technicians or licensed electricians following NFPA 72 and applicable local fire codes.

Key Features

• 18 AWG solid conductors for stable, low-resistance signal runs in fixed installations
• 2-conductor configuration sized for standard initiating device circuit and notification appliance circuit wiring
• Overall foil shield reduces electromagnetic interference on fire alarm signal pairs
• Plenum-rated (FPLP) jacket meets NFPA 90A smoke and flame requirements for air-handling spaces
• 500-foot reel reduces handling and speeds pulls on larger projects

Compatibility

Designed as an OEM-style replacement and new-installation option for 18 AWG 2-conductor shielded plenum fire alarm cable applications in systems requiring FPLP-rated wiring per NFPA 72.

Installation Notes

Installation must be performed by a qualified fire alarm technician or licensed electrician in accordance with NFPA 72, NFPA 90A, and all applicable local codes. De-energize and lock out the fire alarm control panel before making any connections to existing circuits. Maintain minimum bend radius to avoid deforming the foil shield, and dress shield drain wires consistently to a single-point ground to prevent ground loops. Plenum-rated cable must be used in all air-handling space runs where conduit is not provided.
