5320UJ-RED-U1000 is a fire alarm cable rated for FPL (Fire Protective Line) applications, featuring 2 conductors of 18 AWG solid bare copper with foam polyolefin (Datalene®) insulation and a PVC jacket with ripcord. The cable is designed for use in fire alarm addressable systems for audio, control, initiating, and notification circuits, with a UL voltage rating of 300 V RMS and an operating temperature range of -20°C to +75°C. Key electrical characteristics include a nominal conductor DC resistance of 8.4 Ohm/1000ft, capacitance of 13 pF/ft, and a maximum recommended current of 5 Amps per conductor at 25°C. The cable meets NEC Article 760 and UL 1685 flammability standards, with a minimum bend radius of 2 inches and a bulk cable weight of 20.5 lbs/1000ft, making it suitable for reliable fire detection and alarm signaling in commercial and industrial installations.
