Smoke alarm laws state by state. Easy guide, no jargon.

ZEN Smoke Alarms™ are fully certified to Australian Standard AS 3786:2014 and can be legally used in homes across every Australian state and territory, where wireless 10-year sealed battery alarms are permitted.

Across Australia, the National Construction Code (NCC) requires new builds and homes undergoing substantial renovations to use 240V hardwired smoke alarms.

For existing homes, however, most states allow compliant wireless 10-year battery alarms — making ZEN Smoke Alarms a safe, simple and cost-effective option for everyday households.

Below is a quick guide to when wireless, 10-year battery-powered alarms like ZEN are suitable in each state:
