Interconnected smoke alarms are a mandated requirement in certain states and recommended in others. Detector Inspector makes smoke alarm compliance one less thing you have to worry about.
What are interconnected smoke alarms?
Interconnected smoke alarms are designed to communicate with each other and sound in unison when one alarm detects smoke. Essential to fire safety is early detection. Interconnected smoke alarms are the best way to provide early warning for occupants to escape.
Fire can engulf a modern home in just a few minutes. With interconnected smoke alarms, occupants who may otherwise be out of audible range of the detecting alarm will be alerted early enough to act, increasing survivability in a house fire by more than 50%.
Which rental properties require them?
In Victoria, New South Wales and South Australia, properties built after 1 May 2014, must have interconnected smoke alarms where more than one is present.
In Queensland, since 1 January 2022, before a new tenancy begins, an existing tenancy renews or the property is sold, smoke alarms must be photoelectric, interconnected and installed on each storey and in all bedrooms and hallways, powered by mains power or a non-removable 10-year lithium battery.

In Queensland, an office or study will require a smoke alarm unless there is a reason why the space could not also be used as a bedroom.
In other states, existing smoke alarms will be interconnected or new interconnected alarms will be installed to ensure each property is compliant with the smoke alarm legislation applicable in its state.
Victorian¹, New South Wales² and South Australian³ legislation require compliance with the Building Code of Australia (BCA). The BCA provides technical provisions for the design and construction of buildings through the National Construction Code (NCC).
In the case of fire safety requirements, BCA 2014 (E2.2a and Part 3.7.5) in summary requires that smoke alarms must:
- Be installed in all Class 1a (single dwelling) and Class 2 buildings (apartments);
- Comply with Australian Standards (AS 3786)
- Be mains powered and interconnected where the dwelling was constructed after 1 May 2014 and there is more than one alarm in the property.
Of note is the build date requirement of 1 May 2014. Properties built after this date, in Victoria, New South Wales and South Australia must have interconnected smoke alarms where more than one is present.
In QLD, as of 1 January 2022, before a new tenancy begins, an existing tenancy renews or the property is sold, smoke alarms must be upgraded to meet the requirements of the Fire and Emergency Services Act 1990.
This means they must have photoelectric, interconnected smoke alarms installed on each storey and in all bedrooms and hallways, powered by mains power or non-removable 10-year lithium battery.
