Be 110% sure that you’re 100% compliant for your rental house, townhouse or unit

From 1 January 2022, dwellings being sold or leased (or having an existing lease renewed) must have interconnected photoelectric smoke alarms installed:

  • In each bedroom; and
  • In hallways which connect bedrooms and the rest of the dwelling; or
  • If there is no hallway, between the bedroom and other parts of the storey; and
  • If there are no bedrooms on a storey at least one smoke alarm must be installed in the most likely path of travel to exit the dwelling

Interconnected and photoelectrical is a must

  • Photoelectric alarms must comply with AS ‍3786-2014 (and must not also contain an ionization sensor)
  • Interconnected means that when one smoke alarm is activated, all other smoke alarms throughout the property are activated at the same time (for instance, if an alarm activates in a child’s bedroom, you will want to hear it immediately in your bedroom)

Hardwired (with back up) or powered by a non-removable 10-year battery?
The law states that from 1 January 2022 smoke alarms must be hardwired or powered by a non-removable 10-year battery. While a non-removable battery will satisfy the minimum standard for compliance, we recommend that wherever possible your interconnected photoelectric smoke alarms be hardwired to the mains power supply with a secondary power source (i.e. battery). The main reason is the backup provided, and this secondary level of protection is also consistent with laws pertaining to dwellings built (or substantially renovated) from 1 January 2017.


Interconnected photoelectric smoke alarms in every bedroom, and hallways connecting bedrooms to exits.

“I’ve seen enough fires over the years to know that they could have been contained or put out earlier if the right alarm systems and first attack equipment was in place.”
