During the normal supervisory state, the pipings extending up to the sprinkler heads are kept filled with water under pressure by fresh water pressure tank.2. When a fire breaks out and the heat sensitive element of a sprinkler head reaches a specific operating temperature (normally 72°C), the sprinkler head opens and discharges water.3. The flow of water though the sprinkler piping caused by water discharge from the sprinkler head is detected by the automatic alarm valve, which in turn sends an alarm signal to the fire alarm panel.4. At the same time, the pressure within the piping drops. This activates the pressure switch on the fresh water pressure tank, which then starts the pump motor. Thus, water is continuously discharged from the sprinkler head to extinguish the fire.This system is installed in accommodation spaces and other service spaces on the vessels such as passenger ships and car ferries. The sprinkler system is most effective in extinguishing fire in its early stage. Statistics show that about 70% of all fires have been extinguished by less than three sprinkler heads.Diagram Configuration of Automatic Sprinkler SystemAutomatic Sprinkler Systems
