Specifies minimum requirements for the installation, commissioning and testing of combined sprinkler and hydrant systems for installation in multi-storey buildings as an alternative to the installation of separate sprinkler and hydrant systems.

This Standard sets out the minimum requirements for the installation, commissioning and testing of a combined sprinkler and hydrant system, for installation in multistorey buildings as an alternative option to using separate sprinkler and hydrant systems, or separate sprinkler and hydrant installations utilizing a combined fire main (see AS 2118.1).
