The fire detection tube, connected to the extinguisher bottle group via a container valve, is fixed above likely fire locations. When a fire occurs, the pressurized tube softens and bursts at the hottest point, activating the container valve. The fire extinguishing agent is then released through the tube's burst hole. The pressure switch operates to alert the fire control center or ring the alarm bell upon activation.
