Fire alarm cable is a specialized class of power-limited signaling conductor designed to maintain the integrity of life-safety systems during emergencies. These cables serve as the nervous system for building safety, connecting fire alarm control panels (FACP) to essential devices such as smoke detectors, heat sensors, pull stations, and notification appliances like horns and strobes. Available in multiple gauges and conductor counts, fire alarm cables are categorized by their jacket’s fire-resistance: FPLP (Plenum) for use in air-handling spaces and FPLR (Riser) for vertical runs between floors. Engineered with high-purity solid copper for maximum signal reliability, these cables are built to withstand the rigors of commercial and residential safety infrastructure while ensuring every second counts.
Installation Note: Per NEC Article 760, fire alarm circuits must be kept physically separated from light and power circuits to prevent interference and accidental high-voltage contact. When installing in "plenum" spaces (such as drop ceilings used for air return), you must use FPLP-rated cable to prevent the spread of toxic smoke. Always ensure the "drain wire" on shielded versions is properly grounded at the control panel to effectively eliminate electrical noise.
