A Fire Alarm 100 m Cable is a roll of electrical cable designed for connecting fire alarm system components over a distance of up to 100 meters. It is used in fire detection and safety systems to link smoke detectors, heat sensors, alarm panels, sounders, and control modules.This cable is typically fire‐resistant or flame‐retardant, meaning it can maintain circuit integrity during a fire long enough for the alarm system to operate and alert people around.
