Every home in South Australia must have working smoke alarms, and the type required depends mainly on when the home was built and whether it's been sold. The SA Metropolitan Fire Service (MFS) sets out the current rules. NG Elec supplies, installs and tests compliant alarms for homeowners, landlords and agents across Adelaide.

In South Australia, all homes must have working smoke alarms. Newer homes generally need hardwired (240V) alarms, and older homes that have been sold generally need hardwired or 10-year non-removable battery alarms. The MFS publishes the current rules for each type of home. Alarms should meet AS 3786 and be replaced about every 10 years, and hardwiring must be done by a licensed electrician.
Is this you?
Check the date on the back. Sensors lose sensitivity with age, so alarms should be replaced at about 10 years.
Usually a flat backup battery or an alarm past its life. If a new battery doesn't fix it, it's time to replace.
Selling or leasing is a good time to check your alarms meet the current SA rules. We'll check what's there and tell you what's needed.
Alarms generally need to be near sleeping areas and on each level. Bigger homes may need more.
New bedrooms or extensions can change how many alarms you need and where.

Generally at least one on each level, near the bedrooms. Larger or split-level homes may need more. We'll recommend a count from your floor plan and the current rules.
Usually a flat backup battery or an alarm past its 10-year life. Dust and insects can cause false alarms too. If a fresh battery doesn't fix it, replace the alarm.
