Multiple Applications: Fire Protective Signaling Circuits, Smoke Detectors, Strobes/Sirens, Pull Stations, Voice Communications, Burglar Alarms, Audio, Control, Initiating and Notification Circuits, Microprocessor/Addressable Controlled Systems. Pure Copper Conductors: Our fire alarm wire is built with solid bare copper conductors, providing maximum conductivity and reliability to ensure that your systems run smoothly. FPLP (Plenum-Rated): Our cable is designed with your safety in mind. FPLR (Riser-Rated): Our cable is designed with your safety in mind. It features a FPLR/CMR/CL3R/FT4/Riser-Rated flame-retardant rating that provides peace of mind in case of fire. This type of cable is commonly used in commercial projects where enhanced fire safety requirements are needed, exceeding the basic fire safety rating of CM cables. 300V (CL3) Power-Limited Circuit Cable: Our cable is rated at 300 volts and classified as a Class-3 (CL3) Power-Limited Circuit Cable, capable of carrying a surge of up to 300 watts. This makes it a reliable choice that reduces risk of electrical shock for even the most demanding application. Installation-Friendly Design: With its round, slick jacket and smooth edges, our cable is easy to pull through rough corners and edges. The jacket also features a rip cord for effortless removal during installation.
