in a floor area that is not sprinklered throughout, the floor area and the travel distance are not more than the values in Table 3.4.2.1., or
in a floor area that is sprinklered throughout:
- the travel distance is not more than 25 m, and
- the floor area is not more than the value in Table 3.4.2.1..

This applies to floor areas that are intended for occupancy, including mezzanines as stated in Sentence 3.4.2.2.(1), in buildings described in Sentence 1.3.3.2.(1) of Division A.
