Smoke alarms are easy to forget until something goes wrong. But staying on top of regular testing and replacement is one of the most important things you can do to protect your home or workplace. Fires spread fast, and a working alarm gives you those crucial early seconds to act.
If you’ve ever asked yourself how often should smoke alarms be tested or when to change your smoke alarm battery, this guide will help.
Here’s what you need to know to stay safe and compliant.
Monthly Testing is Essential for Safety
If you’re unsure how often you should check your smoke alarm, monthly testing is the minimum. Regular checks help identify flat batteries, faulty sensors, or worn-out units before they become a problem. Simply press the test button and confirm the alarm sounds properly.
This small task can easily be added to your calendar. In workplaces, monthly testing often forms part of a routine electrical maintenance and repair program. For more complex environments, a commercial electrician in Melbourne can assist with scheduling and compliance.
Six-Month Visual Inspections Keep Devices Reliable
Alongside monthly testing, a visual inspection every six months helps ensure your alarm is in top shape.
Look for dust buildup, signs of damage, loose fittings, or lights that aren’t flashing as they should. These issues are often easy to fix, but if ignored, they can stop your smoke alarm from working when it matters most.
This is especially important in older homes or spaces with high ceilings and poor airflow. If you’re not sure what to look for, a 24/7 electrician in Melbourne can conduct a full inspection and recommend next steps.
Batteries Should Be Replaced Every Year
Even if your smoke alarm seems fine, the battery should be changed once a year. This applies to both battery-powered and hardwired alarms with a backup.
Newer models come with long-life lithium batteries, but many Melbourne homes still rely on older units that need regular attention.
If your alarm starts chirping or beeping randomly, that’s your cue to act. Don’t wait for the sound to stop. Knowing when to change a smoke alarm battery helps you avoid those last-minute scrambles in the middle of the night.
Alarm Units Have a Lifespan Too
Smoke alarms aren’t designed to last forever. Most need to be replaced every 10 years, even if they still work.
Over time, sensors become less sensitive, and internal components wear down.
You’ll usually find a manufacture or expiry date printed on the side or back of the unit. If there’s no date or it’s more than 10 years old, it’s time for a new one.
As part of your smart home electrical system, you might consider upgrading to smart smoke alarms. These connect to your phone, sync across rooms, and notify you even when you’re not home. You can read more about the benefits of a smart home electrical system if you’re considering an upgrade.
Regulations for Homes and Businesses in Melbourne
In Victoria, smoke alarms are mandatory in all residential properties and are especially important in rentals, commercial buildings, and industrial settings.
Landlords must ensure working alarms are installed and tested annually. Businesses should also maintain compliance through scheduled servicing, which can be built into your regular electrical maintenance and repair plan.
