AS 2118.4-2012 Automatic fire sprinkler systems, Part 4: Sprinkler protection for accommodation buildings not exceeding four storeys in height
Standards Australia
Supersedes: AS 2118.4-1995 Automatic fire sprinkler systems - Residential
Draft Designation: DR 07420Sprinkler Standards consist of two groups: Systems (AS 2118 series) and Components (AS 4118 series). The complete series comprises the following:
AS
2118 Automatic fire sprinkler systems
2118.1 Part 1: General systems
2118.2 Part 2: Drencher systems
2118.3 Part 3: Deluge systems
2118.4 Part 4: Sprinkler protection for accommodation buildings not exceeding four storeys in height (this Standard)
2118.5 Part 5: Home fire sprinkler systems
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
Changes to the previous (1995) edition of this Standard include the following:
(a) The water supply section has been expanded.
(b) A minimum design flow is specified.
(c) Design criteria for ancillary areas have been revised.
(d) Detailed sprinkler spacing and positioning requirements are included particularly related to obstructions, heat sources and sloped ceilings.
(e) Acceptance testing (commissioning) requirements are detailed.
Wall wetting sprinklers (drenchers) cannot be incorporated in sprinkler systems covered by this Standard. The requirements for such systems are addressed in AS 2118.2.
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.
The use of Notes in this Standard is of an advisory nature only. They provide explanations and guidance on recommended design consideration or technical procedures, as well as an informative cross-reference to other documents or publications.
Originated as AS 2118.4-1995. Second edition 2012.
The purpose of the Standard is to provide design, installation and acceptance testing (commissioning) criteria for sprinkler systems to aid in the detection and control of fires in
accommodation buildings.
A sprinkler system designed and installed in accordance with this Standard is expected to prevent flashover (total involvement) in the room or area of fire origin, and to improve the chance for occupants to escape or be evacuated.
In preparing this Standard, the Committee considered the US National Fire Protection Association (NFPA) publication 13R, Standard for the Installation of Sprinkler Systems in Residential Occupancies up to Four Stories in Height, and the assistance gained from this source is acknowledged.
