Fire Alarm Cable, FPLP, 14/2, Plenum, Unshielded, Red, 1000'

FPLP stands for Fire Power-Limited Plenum cable. It's a type of fire alarm cable specifically designed for use in plenum spaces, which are areas in buildings used for air circulation, such as above dropped ceilings or in ductwork. These cables are rated for use in these spaces because they are constructed with fire-resistant materials that limit flame spread and smoke emission during a fire, important for maintaining visibility and air quality in emergencies.
