Installation of Smoke Detectors That Comply With Australian Standards

03 September 2019

Smoke detectors are mandatory for all residential and commercial buildings across Australia. While certain local authorities may make additional stipulations, all detector installations must comply with Australian Standards. When you fail to adhere to these standards, your buildings will not be safe for use, regardless of their purpose.

A Brief Explanation of the Requirements for Smoke Detectors in Residential Structures

Smoke detectors need to be installed near or on the ceiling of every storey of a residential building. Location of their installations must be ideal for not only alerting awake occupants, but also those who are sleeping. The National Construction Code or NCC classifies residential structures in the following manner:

• Class 1a includes row houses, detached homes, townhouses, villa units and terrace houses

• Class 1b includes guest houses, certain boarding houses and hostels

• Class 2 is for the sole-occupancy units, such as blocks of flats and apartments.

• Class 3 includes residential sections of motels and hotels, backpacker lodging establishments, residential areas of educational facilities and accommodations for children, the disabled or the elderly.

• Class 4 covers the dwellings attached to shops and other non-residential buildings.

The smoke detectors need to comply with the Australian Standard AS 3786. Most of the models sold today should, but it is up to you to be certain of this fact. Also, they need to be hardwired into the electrical mains of the residential buildings along with containing a battery backup for when the power fails if the structures have been built since August 1, 1997. Residential buildings built prior to this day need to comply with the earlier Australian Standard of AS 3786 – 1993. This regulation states that the smoke detectors need to be in the correct locations with battery backups but hardwired versions are not mandatory.

Information about the Regulations for Smoke Detectors in Commercial Buildings

Regulations for smoke detectors in commercial structures are a bit more complicated to explain. However, these detectors need to be part of the essential safety measures set forth by the Victorian Building Act of 1993 along with the 2006 Building Regulations. If the commercial building was built prior to July 1, 1994, the owners need to adhere to the specification in Regulations 1212-1217. However, if the commercial building was constructed after July 1, 1994, the owners need to follow the Regulations 1201-1211. Each set of regulations dictates the specifics clearly.
