    Abstract - (Show below) - (Hide below)

    Specifies the general requirements for the design, installation and commissioning of automatic fire sprinkler systems in buildings.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for the design and installation of automatic fire sprinkler systems in buildings. It also provides for occupancy classification.NOTE: See Appendix A for details of occupancy classification.

    Document Type Standard
    Product Note A 2006 edition of AS 2118.1 has been published. The 1999 edition of AS 2118.1 remains current with AS 2118.1-2006 and continues to be referenced in the BCA. Both the 1999 and 2006 editions will achieve the same objective. The 2006 edition is predicated on advanced technology and may be used as an alternative solution. Where AS 2118.1 is to be applied and the authority having jurisdiction requires the BCA referenced edition, then AS 2118.1-1999 would apply. In all other cases the 2006 edition may be applied.
