Southwire G40005-1A Fplp Fire Alarm Cable 18 Awg 1000 Ft

Product Description

The SOUTHWIRE G40005-1A is a Type FPLP unshielded fire alarm cable designed for plenum-rated fire detection and signaling systems. Built with two 18 AWG bare solid copper conductors, it carries a 300 VAC voltage rating and is jacketed in red LS-PVC for easy visual identification in fire alarm installations. The outside diameter measures 0.145 inches. Rated for temperatures from -20 to 75 degrees C, this cable is listed under UL 1424 and meets NEC Articles 760 and 800. It ships on a 1000 ft reel, making it practical for full-floor or multi-zone pulls on commercial fire alarm projects.

This cable is intended for plenum air-handling spaces where low-smoke, flame-retardant cable is required by code. It suits addressable and conventional fire alarm panel wiring, initiating device circuits, and notification appliance circuits in commercial, institutional, and light industrial buildings. The red jacket serves as a visual identifier for fire alarm conductors in conduit or open plenum runs, consistent with NFPA 72 installation practices. Licensed fire alarm technicians and low-voltage electricians are the primary installers.

Installation Notes

Installation should be performed by a licensed fire alarm technician or low-voltage electrician in accordance with NFPA 72, NEC Article 760, and applicable local codes. De-energize the fire alarm control panel and verify the circuit is isolated before making any terminations. In plenum spaces, secure the cable using listed supports at intervals required by the authority having jurisdiction. Do not exceed the cable voltage rating or bend the cable below its minimum bend radius during routing.
