Application of fire sprinkler concessions under Specification 18 of the NCC

FRNSW interpret the application of the automatic fire sprinkler system concessions under S18C4 of Specification 18 of the National Construction Code (NCC) to only apply to buildings that contain Class 2 or 3 only.

It is the view of FRNSW that these concessions do not apply to other building classes, including multiple classification buildings, such as a Class 2 or 3 building that contains Class 5, 6, 7, 8, 9a or 9b parts.

Note: Permitted concessions, such as the dry fire hydrant concession, do not apply to a multiple classification building.

Whilst FRNSW acknowledges that an FPAA101D and FPAA101H automatic fire sprinkler system are permitted to be installed, in certain circumstances, the concessions identified above do not apply.

Reference should also be made to the FRNSW position Fire sprinklers in Class 2 and 3 buildings.
