To exempt certain buildings from the requirements of Sentence 3.2.5.12.(1) and permit sprinkler systems in such buildings to conform to a different standard on the basis that the different standard is appropriate for such buildings. This [the reference to the different standard] is to limit the probability that automatic sprinkler systems will not meet proper standards, which could lead to such systems not performing in the way intended in a fire situation, which could lead to a fire not being suppressed or controlled, which could lead to the spread of fire to other parts of the building, which could lead to harm to persons.
