NOTE:
Sprinklers shall be grouped into separate sections, each of which is to contain not more than 200 sprinklers. In passenger ships any section of sprinklers shall not serve more than two decks and shall not be situated in more than one main vertical zone.
However, such a section of sprinklers may be permitted to serve more than two decks or be situated in more than one main vertical zone, if it is satisfied that the protection of the ship against fire will not thereby be reduced.
