a discharge tube with a fusible plug,
-
a pressure gage,
-an identification label. The spherical container is made of brass and has a diameter of approximately 60 mm (2.3622 in.). The mounting bracket, the discharge tube and the fill port are attached to the container. The fusible plug installed in the end of the discharge tube seals the tube and keeps the extinguisher agent in the container. The container is charged with the extinguisher agent through the fill valve in the fill port. The extinguisher agent also pressurizes the container. The pressure gage is installed on the fill port after the container is charged. The identification label bonded to the container shows:
-
the part number,
-
the serial number,
-
the date of manufacture,
-
the extinguisher agent type,

4. Operation
_________ The lavatory fire-extinguishing system is completely automatic and self-contained. A fire or overheat condition opens the release mechanism. When the temperature in the waste paper-bin area is approx. 79 DEG.C (174.20 DEG.F) the fusible material in the tip of the discharge tube melts. The lavatory fire extinguisher then discharges completely within 3 to 15 s. Each unit weighs 0.454 kg max. It stores and discharges 100 to 130 g of Halon 1301 into the waste paper bin to extinguish the fire.
