AS 2118.6-2012 Automatic fire sprinkler systems, Part 6: Combined sprinkler and hydrant systems in multistorey buildings
Standards Australia
Supersedes: AS 2118.6-1995 Automatic fire sprinkler systems - Combined sprinkler and hydrant
Draft Designation: DR 08142This edition includes provision for 35 m pressure zones in addition to the 50 m pressure zones introduced in the first (1995) edition. Detailed steps and graphs are included in Appendix G.
The AS 2118 suite of sprinkler Standards has 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 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
2118.5 Part 5: Home fire sprinkler systems
2118.6 Part 6: Combined sprinklers and hydrant systems in multistorey buildings (this Standard)
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
4118.1.7 Part 1.7: Components—Alarms valves (dry)
4118.1.8 Part 1.8: Components—Pressure-reducing valves
4118.2.1 Part 2.1: Piping—General
The use of Notes in this Standard are of an advisory nature only to give explanation or guidance to the user on recommended design considerations or technical procedures, or to provide an informative cross-reference to other documents or publications. Notes to clauses in this Standard do not form a mandatory part for compliance with this Standard.
The terms ‘normative’ and ‘informative’ have been used in the appendices of 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.
Originated as AS2118.6-1995. Second edition 2012.
This Standard sets out minimum criteria for the design, installation and commissioning of combined sprinkler and hydrant systems (including fire hose reels where appropriate) in multistorey buildings greater than two storeys in height.
NOTES:
1: The installation of a combined system to this Standard is a choice; it is not mandatory to install a combined sprinkler and hydrant sprinkler system in multistorey buildings.
2: This Standard does not apply to buildings less than three storeys in height, for example, large floor area factories and warehouses where the sprinkler and hydrant systems are normally provided to AS 2118.1 and AS 2419.1 respectively. Such buildings may have an in-ground common fire ring main (see AS 2118.1).
3: This Standard should not be used for sprinkler systems classified as high hazard (see AS 2118.1 and Appendix M).
