This Standard specifies minimum requirements for the components, design, installation, commissioning and maintenance of automatic home fire sprinkler systems for one- and two-family homes. It provides two options, namely an independent piping system serving fire sprinklers only or a combined piping system serving both the fire sprinklers and the domestic plumbing fixtures.This Standard is intended to provide a degree of life safety and property protection for the occupants of one- and two-family homes as follows:(a) Single dwellings, detached houses.(b) Terrace houses, townhouses, villa units (multiple adjoining dwellings which are separated by fire rated walls).(c) Moveable or relocatable dwellings.(d) Cabins.(e) ‘Granny’ flats.This Standard does not apply to residential occupancies covered by AS 2118.1 (general systems) and AS 2118.4 (residential systems).NOTES: 1 This Standard provides minimum requirements; however, in certain circumstances, such as concealed spaces used for storage purposes, extended protection may be considered. Guidance on optional additional protection is given in Appendix A.2 The installation of smoke alarms forms an integral part of the requirements of this Standard.3 The design criteria in this Standard are aimed at maintaining survival conditions for a period of at least 10 min during which it is assumed that evacuation will be accomplished.4 Consumer information is provided in Appendix B.5 Guide to function and benefits of home sprinklers is provided in Appendix C.6 Information on maintenance is given in Appendix D.
