Smoke Alarm Upgrades in Adelaide's North East
Having smoke alarms doesn't automatically mean your home has the right protection.
This is something I see regularly in established homes.
An alarm gets replaced here, another gets added during a renovation, and before long there's a mixture of different alarms installed at different times.
That's important because South Australia's smoke alarm requirements have changed several times, and what applies to a home depends on things like when it was built, whether it's changed ownership and whether it's been extended or renovated. The MFS specifically tells homeowners to consider these things when working out what alarms are required.
Frequently Asked Questions
Take the alarm down and look on the back. You'll find the manufacture date printed on the label. If it's 10 years old or more, it's time to replace it.
Not necessarily. The test button checks that the electronics are working, but it doesn't confirm the smoke sensing chamber is still performing as intended after years of ageing. That's why manufacturers recommend replacement after 10 years.
Yes. Photoelectric smoke alarms provide earlier warning for many common household fires and are the type recommended for residential properties in South Australia.
If your other alarms are approaching ten years old as well, replacing them together is often the better long term option.
Absolutely. I'll inspect your existing smoke alarms, explain what you've currently got and let you know whether they meet the current South Australian requirements. If you'd like to check for yourself first, the SA Metropolitan Fire Service Smoke Alarm Quick Guide is a great place to start, as it steps you through the requirements based on your home's age, ownership history and any major renovations.
Because smoke alarms are a bit like tyres on your car. They slowly wear out over time, even if they look perfectly fine from the outside. Replacing them every ten years means you can have confidence they'll perform properly if you ever need them.
