The final compliance deadline for existing homes

North Lakes follows the Queensland-wide requirements. The law applies to existing houses, townhouses and units throughout the suburb.

The quick answer

What a compliant smoke alarm system requires

A few older alarms in the hallway may not be enough. Compliance depends on the alarm type, age, power source, interconnection and placement.

1

Photoelectric alarms

The alarms must be photoelectric and comply with Australian Standard AS 3786–2014.

2

Inside every bedroom

Each bedroom needs its own compliant alarm. Hallway-only systems may need additional alarms.

3

Connecting areas

Hallways or areas connecting bedrooms with the rest of the home also need an alarm.

4

All interconnected

When one alarm detects smoke, every interconnected alarm in the dwelling must sound.

Placement rules

Where do alarms need to go?

  • ✓Inside every bedroom.
  • ✓In hallways connecting bedrooms with the rest of the home.
  • ✓If there is no hallway, between the bedrooms and the rest of that storey.
  • ✓On a storey without bedrooms, in the most likely exit path.

Installation clearances matter

Where practicable, alarms are installed on the ceiling. They should not be installed within:

  • 300 mm of a ceiling and wall corner
  • 300 mm of a light fitting
  • 400 mm of an air-conditioning vent
  • 400 mm of a ceiling-fan blade
Smoke alarm estimator

Estimate how many alarms your North Lakes home may need

Answer a few questions about the number of storeys, bedrooms and connecting areas. The result is indicative and can be sent directly with an installation request.

Typical examples

How the estimated alarm count is calculated

The final number depends on the actual layout, but these examples show why bedroom count alone is not enough.

4 alarms

Three-bedroom single-storey home

3 bedroom alarms + 1 shared connecting-area alarm.

5 alarms

Four-bedroom single-storey home

4 bedroom alarms + 1 shared connecting-area alarm.

6 alarms

Four-bedroom two-storey home

4 upstairs bedrooms + 1 upstairs hallway + 1 downstairs exit-path alarm.

Power and replacement options

Do all smoke alarms need to be hardwired?

No. The right solution depends on the existing system and the work being completed.

Existing battery alarms Compliant photoelectric alarms with a non-removable 10-year battery may be suitable.
Existing hardwired alarms A hardwired alarm that requires replacement must be replaced with a compliant hardwired photoelectric alarm.
New homes and major renovations Hardwired interconnected photoelectric alarms are required.
Common problems

When your existing alarms need attention

More than 10 years old Alarms must be replaced once they reach 10 years of age.
Only one alarm sounds The alarms may not be correctly interconnected.
Random beeping or nuisance alarms Age, dust, insects, placement, batteries or electrical faults may be responsible.

Owner-occupiers, landlords and sellers

Frequently asked questions

North Lakes smoke alarm questions answered

Do I need a smoke alarm inside every bedroom?
Yes. A compliant photoelectric alarm is required inside every bedroom, as well as in the connecting hallway or area.
How many alarms does a four-bedroom home need?
A four-bedroom single-storey home with one shared connecting area may require five alarms. Separate bedroom wings or another storey can increase the number.
Does downstairs need an alarm if all bedrooms are upstairs?
Yes. A storey without bedrooms needs at least one alarm in the most likely path of travel to exit the home.
Can battery-powered alarms still comply?
Yes. In an existing dwelling, suitable alarms may use a non-removable 10-year battery. They must still be compliant, photoelectric, interconnected and correctly positioned.
Do I need an electrician?
A licensed electrician is required when the work involves a 240-volt electrical connection. Battery-powered devices do not necessarily require electrical work, but correct placement and interconnection still matter.
Why does my alarm beep for no obvious reason?
Possible causes include age, dust, insects, a failing battery, unsuitable placement, a faulty alarm or an electrical issue in a hardwired system.
How often should alarms be tested?
Test smoke alarms monthly and confirm that all interconnected alarms sound. Clean them according to the manufacturer’s instructions.
How much does installation cost?
Cost depends on the alarm count, existing wiring, access, interconnection method and any faults requiring correction. Use the estimator and submit the result for an accurate installation quote.
