Smoke Alarm Compliance in Dubbo
NSW Smoke Alarm Requirements
NSW law requires photoelectric smoke alarms (not ionisation type) in all residential properties. For new buildings and major renovations completed after 2023, interconnected alarms must be installed in every bedroom and hallway on each level. For existing older homes, a smoke alarm on each level remains the minimum legal requirement.
Rental properties have the most specific obligations — landlords must install compliant smoke alarms, test them annually, replace batteries, and ensure they function at the start of each tenancy.
Why Interconnected Alarms Matter
Interconnected smoke alarms all sound when any one is triggered. In a multi-level home, this means a fire starting in the basement can wake occupants in upstairs bedrooms — often the difference between escaping safely and not.
Hardwired interconnected alarms are the most reliable option — they maintain interconnection even if battery backup fails and don't rely on RF signals between units. We install hardwired photoelectric smoke alarms across Dubbo for both residential and rental properties.
