Automatic sprinkler, a fire extinguishing device installed in a convenience facility area or service area of ships like passenger ships or car ferries, is most effective for early stage of fire control operation.

Mostly About 70% of fires can be initially controlled with less than three sprinkler heads.


In normal management conditions, the pipe linked to the head of sprinkler is filled with water by the pressure of fresh water pressure tank, and if fire breaks out and the heat sensing element at the sprinkler head reaches a specific operating temperature(usually 72℃), the sprinkler head opens and the water discharges.

If water flows through the sprinkler pipe and automatic alarm valve senses it while water is discharged from the sprinkler head, this automatic alarm valve in turn sends the alarm signal to fire alarm panel, and at the same time, the pressure within the pipe drops as the pressure switch of the fresh water pressure tank operates. And then pump motor is driven and water continues to be discharged from the sprinkler head until the fire is subdued.
