NZS 4515:2009
Fire sprinkler systems for life safety in sleeping occupancies (up to 2000 square metres)
Applies to buildings used solely as a residence. NZS 4515 includes care institutions, hostels, boarding houses, apartment buildings, motels, retirement homes, rest homes, transitional houses, and hospital ward areas. The 2009 version of the Standard places a greater emphasis on the life safety characteristics of sprinkler systems, as opposed to their property protection characteristics. This Standard recommends the use of residential sprinkler heads as a number of important benefits are derived from their rapid response and fire control.
