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. Shielding Performance: The aluminum foil shielding layer prevents electromagnetic interference (EMI) from affecting the signal transmission within the cable. By blocking external interference, the aluminum foil ensures that the signal remains clear and free from distortion. FPLP (Plenum-Rated): Our cable is designed with your safety in mind. It has the flame retardant grade of FPLP/CMP/CL3P/FT6/Plenum-Rated and is the highest flame retardant cable. This cable suited to go in the plenum spaces of buildings such as ceilings and enclosures, that are also used by the building for air distribution systems to transport air. CMP is higher than commercial grade cable CMR and civil grade cable CM. 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.
