Smoke alarm checks and replacements
Our teams of expert electricians regularly help Adelaide homes and businesses with their smoke alarm related jobs, including:
Testing and checking existing alarms (scope confirmed per site)
Replacing alarms that are old, faulty, or no longer reliable
Installing new alarms in additional areas (as part of upgrades or renovations)
Checking basic placement considerations and wiring condition (general guidance)
A simple smoke alarm checklist
Hardwired and interconnected smoke alarms
Some properties use hardwired alarms, and some setups include interconnected alarms that trigger together. A hardwired smoke alarm is one that runs on the home’s 240V mains power, usually with a backup battery so it still works during a blackout, whereas an interconnected smoke alarm system means that when one alarm detects smoke, every linked alarm sounds at once. In South Australia, homes built from 1 January 1995 have required mains-powered smoke alarms, and since 1 May 2014 new dwellings, additions and extensions that need multiple alarms must have those alarms interconnected.
