Bottom Line
Verdict
Hardwired alarms connected to 240V mains power with battery backup are more reliable long-term (mains power means no forgotten batteries) and are the standard for new construction. However, installation requires a licensed electrician to run cable between locations, adding $50–$80 per alarm in labour. Wireless RF-interconnected alarms avoid this wiring cost and are fully compliant under Australian regulations — they are ideal for retrofits in existing homes where running new wiring is impractical or expensive. Both types must be photoelectric.
Choose hardwired interconnected alarms for new builds and major renovations where wiring can be easily installed during construction. Choose wireless RF-interconnected alarms for existing homes, rental properties needing cost-effective upgrades, heritage properties with limited ceiling access, and any situation where running new wiring would be disruptive or expensive. Wireless systems cost $50–$100 more in alarm hardware but save $200–$400 in electrician wiring time.
Comparison FAQ
Smoke Alarm Solutions is cheaper on average in this comparison, but the right answer depends on your specific smoke alarm requirements including alarm type, interconnection method, property size, and whether a compliance certificate is required.
Alarm type (photoelectric is required by law), interconnection method (hardwired or wireless), number of alarms needed, whether a compliance certificate is included, and whether hardwired installation requires a licensed electrician usually affect the total cost more than a blended average. Always confirm what is included in the quote and whether a compliance certificate will be issued.
