All Victorian residential properties must have smoke alarms on every level. This includes all houses, units, flats and townhouses. Smoke alarms must meet Australian standard: AS 3786.

Install smoke alarms with a 10 year-long-life battery. If you have a smoke alarm with a 9-volt battery, replace the battery every year.
If your smoke alarm emits a single, occasional beep, you need to change the battery, or the smoke alarm may be faulty and you need to replace it.
