Specifies the design, installation and commissioning of sprinklers for life safety and property protection for the inhabitants of low-rise Class 2 and Class 3 buildings as defined in the BCA. In addition to providing an increased level of protection to building occupants, This Standard also considers the economic aspects of the sprinkler system. The purpose of this Standard is to provide design and installation requirements for a life safety sprinkler system in addition to smoke alarms, to aid in the detection and control of fires in residential occupancies and thus provide improved protection against injury and loss of life. A sprinkler system designed and installed in accordance with this Standard is expected to prevent flashover (total involvement) in the room of fire origin and to improve the chance for occupants to escape or be evacuated.
