The fire detection tube is connected to the fire extinguishing agent bottle group by the container valve and placed above likely fire sources for detection. In a fire, the tube softens and bursts at the hottest spot, activating the container valve. The agent is then released through the pipe and nozzle to extinguish the fire, while the pressure switch operates to notify the fire control center or ring the alarm bell.
