Draft Designation: DR 06464Reconfirmed by: AS 2118.5-2008 REC:2020 Automatic fire sprinkler systems, Part 5: Home fire sprinkler systems
This Standard was developed taking into consideration local and international Standards
including NZS 4517—2003, Fire sprinkler systems for domestic occupancies, NFPA 13D,
Standard for Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes and BS 9251:2005, Sprinkler systems for residential and domestic occupancies. Code of Practice.
The sprinkler Standards have been restructured into two groups: Systems (AS 2118 series) and Component (AS 4118 series) The complete series comprises the following:
AS
2118 Automatic fire sprinkler systems
2118.1 Part 1: General requirements
2118.2 Part 2: Wall wettings sprinklers (Drenchers)
2118.3 Part 3: Deluge
2118.4 Part 4: Residential
2118.5 Part 5: Home fire sprinkler systems (this Standard)
2118.6 Part 6: Combined sprinkler and hydrant
4118 Fire sprinkler systems
4118.1.1 Part 1.1: Components—Sprinklers and sprayers
4118.1.2 Part 1.2: Components—Alarm valves (wet)
4118.1.3 Part 1.3: Components—Water motor alarms
4118.1.4 Part 1.4: Components—Valve monitors
4118.1.5 Part 1.5: Components—Deluge and pre-action valves
4118.1.6 Part 1.6: Components—Stop valves and non-return valves
4118.1.7 Part 1.7: Components—Alarm valves (dry)
4118.1.8 Part 1.8: Components—Pressure-reducing valves
4118.2.1 Part 2.1: Piping—General
This Standard incorporates a Commentary on some of the clauses. The Commentary directly follows the relevant clause shown in italic font-type and enclosed in a panel. The Commentary is for information only and does not need to be followed for compliance with the Standard. Commentaries on clauses explain the purpose of a clause and give, in some cases background information.
The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.
Notes in this Standard are advisory only.

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.
