The New Zealand Building Code acceptable solution C/AS1 classifies the types of fire alarm systems as follows:
Domestic smoke alarm system
A manual fire alarm system only, activated by manual call points
An automatic fire alarm activated by heat detectors and manual call points
An automatic fire alarm system, activated by smoke detectors and manual call points
A variation to a Type 4 that allows smoke detectors in some fire cells to sound as a local alarm only, provided that heat detectors are also installed in those fire cells
