Smoke Alarm Rules in Victoria: What Wyndham Homeowners & Landlords Need to Know
Victorian smoke alarm requirements explained: AS 3786 photoelectric alarms, 240V interconnection, rental compliance and what to do in older Werribee homes.
Smoke alarm rules in Victoria are stricter than most people realise. Here's a plain-English run-down for Wyndham homeowners, landlords and renovators.
The current standard
Under the Victorian Building Regulations, all new builds and significant renovations must have 240V mains-powered, interconnected photoelectric smoke alarms to AS 3786, with a 9V battery backup. Interconnected means when one alarm sounds, they all sound — critical at night.
Older Werribee homes
Plenty of 1970s–90s homes around Werribee, Hoppers Crossing and Laverton still have a single battery-only ionisation alarm in the hallway. That's no longer best practice — and won't pass a recent insurance assessment. Photoelectric mains-wired alarms respond much faster to smouldering fires (the type that kill at night).
Landlords & rental properties
Victorian rental providers must:
- Ensure alarms are installed and working at the start of every tenancy.
- Test alarms annually and replace expired units (most have a 10-year life printed on the back).
- Keep records of safety checks.
Werribee Electrical helps landlords across Werribee, Point Cook, Tarneit and Wyndham Vale arrange annual checks and replacements with licensed local electricians who issue a Certificate of Electrical Safety (CES) for prescribed work.
Quick checklist
- One alarm per storey, plus every bedroom and hallway leading to bedrooms.
- Photoelectric type (AS 3786).
- Interconnected (RF or hard-wired).
- 240V with 9V battery backup.
- Replaced every 10 years from the date on the back.
