10-Year Lithium Battery Smoke Alarms

  • These alarms are DIY-friendly, as they don’t connect to mains power.

  • They must still be interconnected, either wirelessly or via a network.

  • Correct placement (bedrooms, hallways, every level) is still a legal requirement.

Wireless Interconnected Alarms

  • Approved for compliance in QLD.

  • Can often be installed without an electrician.

  • Ideal for retrofits where hardwiring is disruptive.

Key Rule: If the alarm involves any wiring, only a licensed electrician can perform the installation.

Placement Rules for Compliance

Smoke alarms should be:

  • Installed on ceilings, at least 300mm from walls or fittings.

  • In every bedroom, hallways, and pathways to exits.

  • On every story of multi-level homes.

Avoid installing near fans, air vents, or windows where airflow can delay detection.

Why Compliance Matters

  • Legal Requirement → Fines and penalties apply for non-compliance.

  • Insurance → Claims may be rejected if smoke alarms aren’t compliant.

  • Safety → Interconnected photoelectric alarms give the earliest warning in a fire.
