Wall-Wetting Sprinklers 2016-11-21T08:52:57+00:00

Wall-Wetting Sprinklers

The Building Code of Australia allows a wall-wetting sprinkler system to be installed to provide fire protection to walls or openings in a wall in the event of a fire. A wall-wetting sprinkler system can be used internally or externally and would be nominated as an essential safety measure by the building surveyor/ building certifier.

Building Code of Australia

Part C3 Protection of Openings, clause C3.4 Acceptable methods of protection, nominates the use of wall-wetting sprinklers. No specific Australian Standard is referenced in the BCA relative to the installation of a wall-wetting sprinkler system. Building surveyors require designers to refer to AS 2118.2-2010 Automatic fire sprinkler systems – Drencher systems, for guidance.

The following illustration depicts an external wall-wetting sprinkler over a vent opening.

The following is a part extract of clause I1.1 for an Essential Safety Measure (as appeared in BCA 2013) known as wall-wetting sprinklers:


Safety Measures BCA Provision for Determining Standard of Performance
Wall-wetting sprinklers (including doors and windows required in conjunction with wall wetting sprinklers) C3.4, C3.8, C3.11,
D1.7, D1.8, G3.8

Essential Safety Measures Audit – Wall-Wetting Sprinklers

An essential safety measures determination/ schedule will nominate a wall-wetting sprinklers system as an essential safety measure. An auditor should check the system and report any wall – wetting deficiencies in the building’s essential safety measures logbook to allow the signing of the Annual Statement, Annual Certificate Compliance, Annual Fire Safety Statement, Annual Maintenance Statement and Annual Occupiers Statement.
