Why Smoke Alarm Compliance Matters

A working smoke alarm gives you early warning in the event of a fire — but that only happens if it’s correctly installed, placed in the right location and maintained. New laws require interconnected, photoelectric smoke alarms in all bedrooms, hallways and on each level of the home.


Our services include:


  • Choosing photoelectric alarms that respond faster to smouldering fires compared to older ionisation types.
  • Installing alarms in every bedroom, hallway and on each storey of the home to meet current QLD regulations.
  • Interconnecting alarms so they all sound at once — giving everyone in the home more time to react.
  • Wiring alarms directly into mains power, with battery backup in case of outages.
  • Testing placement and performance to ensure each alarm is working exactly as it should.


If your home hasn’t been inspected or updated recently, it’s time to make smoke alarm safety a priority.

Frequently Asked Questions

  • What are the smoke alarm laws in Queensland?

    As of 1 January 2022, all homes being sold or leased in Queensland must have interconnected photoelectric smoke alarms installed in every bedroom, hallways connecting bedrooms, and at least one on each level of the home. These alarms must be hardwired to the mains power supply with a battery backup or be powered by a non-removable 10-year battery. From 2027, these rules will apply to all owner-occupied homes as well. The goal is to provide earlier warnings and increase safety for occupants during a fire.

  • What is the difference between photoelectric and ionisation alarms?

    Photoelectric alarms detect visible smoke, making them more effective at sensing slow, smouldering fires — the type most likely to cause fatal house fires. Ionisation alarms, on the other hand, detect smaller combustion particles and are better at sensing fast flaming fires. However, they are more prone to false alarms and respond slower to the type of fires that occur during sleep. This is why photoelectric alarms are now the legal requirement in Queensland homes.

  • How often should smoke alarms be replaced?

    Smoke alarms should be replaced every 10 years, regardless of whether they appear to be functioning. Over time, dust, insects and humidity can affect their sensors, reducing sensitivity. The manufacture date is usually printed on the alarm casing — if it’s more than 10 years old, it’s due for replacement. Regular testing and cleaning should also be done every month to keep alarms working properly.
