Just like every other Australian state and territory, it is mandatory in South Australia for working Australian Standard 3786 compliant photoelectric smoke detectors to be fitted into every home. Fines can be imposed if smoke detectors are not installed, and in rental properties the onus is on landlords to ensure the photoelectric smoke detectors are working.
Smoke Detectors And The Law In South Australia
The governing legislation for smoke detectors in South Australia is the Planning Development and Infrastructure (General) Regulations 2017.
The Planning and Development Infrastructure (General) Regulations 2017 call out minimum requirements for smoke detectors in dwellings. To summarise, they state that smoke alarms must comply with the Building Code of Australia (BCA);
Smoke Detectors In Existing Homes Or Residential Properties Built Prior To 1 Jan 1995
A battery powered smoke alarm may be installed in these premises subject to any change of ownership conditions.
When an existing house built prior to 1995 is sold, the owner then has 6 months from the date of title transfer to install photoelectric smoke alarms which are either 240 volt hardwired or are a 10 year life non-removeable lithium battery fire alarm.
Smoke Detectors In New Houses Or Residential Properties Built After 1 Jan 1995
The Building Code of Australia requires 240v mains powered photoelectric smoke alarms.
Smoke Detectors In Houses Or Residential Properties Built After 1 May 2014
South Australian Smoke Alarm Legislation has evolved over the years and requirements vary depending upon the age of your home and when it was constructed. The below flowchart is provided courtesy of the South Australian Metropolitan Fire Service and may help you understand your smoke alarm requirements.

The governing piece of smoke alarm legislation in the Northern Territory is called the Northern Territory Fire and Emergency Regulations 1996 (as in force 1 October 2019).
Northern Territory smoke alarm laws – N.T Fire and Emergency Regulations 1996
N.T Fire and Emergency Regulations 1996 – Smoke Alarms
Part 2A of this regulation details requirements relating to smoke alarms, notably to do with the type of alarm, installation, maintenance and testing. A summary is provided below;
All owners of residential property must have working fire alarms installed and tested annually.
Any existing ionization alarms must be replaced with the photoelectric type when they no longer work, the property is sold, or premises are rented out or a lease is renewed.
Within 30 days before the start of a tenancy agreement in relation to residential premises or a moveable dwelling, the owner of the premises or dwelling must test the fire alarms and replace any that do not function.
The responsibility for testing the alarm in a tenanted property lies with the tenant (after the lease has started). The tenant must advise the owner or agent if the alarm does not work.
Section 13A (3) of the regulation states that an approved smoke alarm means a photoelectric type that:
(a) complies with Australian Standard 3786 and;
(b) is hard wired or is a sealed 10 year lithium battery fire alarm.
Where Do I Install Fire Alarms In The Northern Territory?
The N.T regulations state that smoke alarms must be installed in residential premises according to the Building Code of Australia, section 3.7.2.3. What this means is that fire alarms in the Northern Territory must be installed;
on or near the ceiling in any storey containing bedrooms
between each part of the dwelling containing bedrooms and the remainder of the dwelling; and
where bedrooms are served by a hallway, in that hallway; and
any other storey not containing bedrooms.
Northern Territory Fire Alarm Requirements For Caravans
For a caravan in the Northern Territory, the regulation states that one smoke alarm must be installed on the ceiling of the caravan.

In Tasmania, all homes must be fitted with a working photoelectric smoke alarm on every level. Smoke alarms must be compliant with Australian Standard 3786:2014. Photoelectric smoke detectors need to be installed in every corridor or hallway associated with a bedroom, or if there is no corridor or hallway, in an area between the bedrooms and the remainder of the building. This is a requirement of the National Construction Code of Australia
Smoke Detectors In Properties Built After 1 August 1997
Homes built or substantially renovated after the 1st of August 1997 require 240V hardwired photoelectric smoke detectors, and there must be at least one smoke detector on each level.
Smoke Detectors In Properties Built After 1 May 2014
All properties built or substantially renovated after the 1st of May 2014 must have 240V hardwired photoelectric smoke detectors and be interconnected, so that when one activates, they all activate.
Photoelectric Alarms And Australian Standard 3786:2014
This informative blog post will reveal key secrets about your photoelectric smoke alarm and compliance with the Australian Standard. Understanding these details is essential to ensure your photoelectric smoke alarm is legally compliant and offers reliable protection. Failing to meet the required standards could result in serious safety risks, as well as potential issues with insurance claims in the event of a fire.
All photoelectric smoke alarms sold in Australia must comply with Australian Standard 3786:2014. One of the most important sections, 4.22.1, outlines the mandatory markings and information that must be displayed directly on the smoke alarm itself. These markings provide critical details about the alarm’s compliance, performance, and proper usage.
Unfortunately, many cheap, non-compliant alarms sold online may lack the necessary markings, even if they falsely claim to meet Australian standards. If an alarm does not display this required information, it is technically non-compliant, putting your safety and insurance coverage at risk. Make sure you choose a trusted brand like ZEN Smoke Alarms to guarantee full compliance and peace of mind.
Photoelectric Smoke Alarm Marking Requirements
Have a look at the photoelectric smoke alarm on your ceiling to double check if it has the following information.
4.22.1 Smoke alarm
Each smoke alarm shall be legibly and indelibly marked with the following:
(a) The number and date of this Standard (i.e. AS 3786:2014).
(b) The name or trademark and address of the manufacturer or supplier.
(c) The model designation (type or number).
(d) The type of smoke alarm (type A or type B), e.g. photoelectric or ionization.
(e) The alarm condition aural signal pattern (ISO 8201 or ISO 7731).
(f) The date of manufacture which may be coded into a serial number or the batch
number.
(g) The recommended date for replacement, subject to normal, regular maintenance
NOTE: Provision may be made for a place to note the date for replacement of the smoke
alarm.

Photoelectric Smoke Alarms With 10 Year Battery
For a battery-powered smoke alarm that includes a sealed, non-replaceable 10-year lithium battery, Australian Standard 3786:2014 mandates that a specific warning must be clearly displayed on the device. This ensures that users are aware that the battery cannot be removed or replaced and that the entire unit must be replaced at the end of its lifespan.
The required warning is:
WARNING: BATTERY NOT REPLACEABLE—SEE INSTRUCTION MANUAL.
This warning helps prevent tampering, ensuring the alarm remains fully functional for its entire 10-year lifespan. Always check for this marking to confirm that your smoke alarm meets Australian safety standards and provides reliable long-term protection.

Photoelectric Smoke Alarms – ‘DO NOT PAINT’ Marking
Additionally, a clear notice stating ‘DO NOT PAINT’ must be marked on the outer surface of the smoke alarm enclosure. The letters must be at least 3 mm high and remain plainly visible after installation to ensure homeowners do not accidentally cover or obscure them. This small yet important detail is a legal requirement under Australian Standard 3786:2014 and is often overlooked by cheap, non-compliant smoke alarms found in online marketplaces.
Many low-cost ‘knock-off’ smoke alarms may claim compliance with Australian standards but fail to include all required information. While this might seem trivial, insurance companies could verify these details when processing claims after a house fire. If your smoke alarm lacks the necessary markings or certification, your claim could be denied, leaving you with devastating financial and personal losses. Choosing a fully compliant, Australian Standard-certified smoke alarm like ZEN ensures your home is protected, and your insurance remains valid.

Photoelectric Smoke Alarm Packaging – Essential Info
Section 4.22.2 of the Australian Standard 3786:2014 specifies the mandatory information and data that must be included on both the photoelectric smoke alarm’s packaging (the box it comes in) and in the user manual. This ensures that consumers receive clear, accurate details about the alarm’s performance, compliance, and proper usage.
Just like the markings on the smoke alarm itself, this packaging and manual information is not optional—it is a legal requirement. If this information is missing, the smoke alarm is technically non-compliant, meaning it does not meet Australian safety standards and may be unsafe or unreliable in an emergency. Always check for this crucial information before purchasing a smoke alarm to ensure it meets the highest safety standards.
4.22.2 Packaging
The point-of-sale packaging shall be marked with the following:
(a) The model designation (type or number).
(b) The type of smoke alarm (type A or type B) and an explanation of the meaning of the type designation (e.g. photoelectric or ionization).
(c) The nominal sound level output.
(d) The alarm condition aural signal pattern (ISO 8201 or ISO 7731).
(e) For smoke alarms using 520 Hz alarm condition signal frequency, the nominal frequency.
(f) For type B smoke alarms, permanently marked with the trefoil symbol, and name of
radionuclide and activity. The markings shall be visible from the outside of the packaging.
(g) The maximum number of interconnectable smoke alarms.
(h) Statement if the smoke alarm is suitable for wall (vertical) mounting.

Summary
In summary, Section 4.22 of the Australian Standard 3786:2014 outlines the essential information that must be displayed on the photoelectric smoke alarm, its packaging, and the instruction manual. This ensures consumers receive accurate details regarding compliance, functionality, and installation. Adhering to these requirements is not optional—manufacturers and retailers must comply to sell smoke alarms legally in Australia.
In Queensland, legislation mandates that all smoke alarms must be photoelectric, interconnected, and conform to Australian Standard 3786:2014. Non-compliant alarms could lead to serious consequences, particularly in the event of an insurance claim after a house fire. Using certified, Australian Standard-compliant alarms like ZEN helps ensure your home meets legal and safety requirements, protecting both lives and property.
