Fire can be devastating for Australian households, and with our intense bushfire seasons, the risk is even higher. Staying prepared against these risks is essential to give you and your loved ones the best chance of evacuating safely if needed, which is why smoke alarms — often the first defence against the threat of fire — are a vital addition to any home.
Selecting the right alarm type, choosing the correct placement, and ensuring sufficient coverage is integral for people to get the most out of their smoke alarms. However, many people unknowingly err in one or more of these areas, resulting in lower efficiency. That’s why this guide aims to highlight common fire alarm installation mistakes and how to avoid them.

1. Installing Smoke Alarms in the Wrong Places
While it’s reasonable to assume you should have a smoke alarm for every room, the truth is that proper placement of smoke alarms in Australia is a lot more impactful than you think.
If your alarm isn’t in the right spot, it might lead to frequent false alarms (which can make you complacent when there is an actual fire), and it might not detect smoke in time. This can cause you to lose precious seconds in reacting to a fire, which can make all the difference.
Where Not To Place Smoke Alarms
Kitchen and/or Bathroom: Cooking smoke and steam can trigger false alarms, leading to owners disabling their smoke alarms out of frustration and rendering them useless.
Near Well-Ventilated Areas: This can include windows, air vents, or even fans. The constant airflow from these locations pushes smoke particles away from your detectors, potentially delaying any sensing of true fires.
In Corners or Tight Spaces: While smoke rises, it doesn’t spread as much and may take time to reach alarms that are hidden away in corners, which means a slower alert.
Ideal Locations For Smoke Alarms
Inside and Outside Bedrooms: Placing smoke alarms in and near sleeping areas ensures that everyone is alerted to any fire danger, even while they’re asleep. This is especially important in homes with multiple occupants.
On Every Level of Your Home: Fires can start anywhere, so it’s crucial to have at least one smoke alarm on every floor, including the basement, to provide full coverage.
Hallways and Main Living Areas: Smoke spreads quickly, and these high-traffic areas act as natural pathways, making them great spots for early detection.
Away from Walls and Corners: Installing smoke alarms at least 30 cm away from walls and corners helps improve airflow around the detector, allowing it to sense smoke more effectively.
2. Using The Wrong Type Of Alarm
Not all fire alarms are designed to detect the same types of fires, and using the wrong one can put your safety at risk.
A common mistake homeowners make is installing heat alarms instead of smoke alarms. Heat alarms detect high temperatures rather than smoke, making them ideal for kitchens and garages where smoke from cooking or vehicle exhaust may cause false alarms.
However, heat alarms are not a great option in areas where early fire detection is crucial (such as living rooms, bedrooms, and hallways). This is because they respond to rising temperatures rather than smoke; they often take longer to activate than smoke detectors, reducing the time you have to react in an emergency.
So, to ensure that you have the right alarms for your home:
· Use photoelectric smoke alarms in bedrooms, hallways, and living areas to detect slow, smouldering fires.
· Install heat alarms only where necessary, such as in kitchens and garages, to prevent nuisance alarms.
· Consider dual-sensor alarms, which combine heat and smoke detection for broader protection.
· Ensure all alarms comply with Australian safety standards (AS/NZS3786:2014) for maximum reliability.
3. Not Having Interconnected Smoke Alarms
Following a report by The Australian Building Codes Board that homes with interconnected alarms could cut fire-related fatalities by up to 50%, interconnected smoke alarms have been mandatory in newer buildings in Victoria and New South Wales since a decade ago, while Queensland requires owner-occupiers to install interconnected smoke alarms in their buildings by 2027.
Having interconnected smoke alarms ensures that if one smoke alarm sounds, it triggers every other smoke alarm in your home to sound as well, alerting everyone no matter where they may be. Having a faster warning means better odds of you escaping or even giving you enough time to put out the fire with an extinguisher if it hasn’t spread.
Modern wireless smoke alarms make interconnecting easier than ever (no complicated wiring required!). If your smoke alarms aren’t linked, consider updating your system.
4. Forgetting to Test and Maintain Your Smoke Alarms
Most people install their smoke alarms and reckon that they will work forever. But just like any other device, your smoke alarms require consistent maintenance for them to work properly. A non-functioning smoke alarm is as good as not having one at all.
Some simple maintenance tips include:
· Testing your alarms monthly by pressing the test button.
· Replace your batteries yearly or as recommended by the manufacturer (unless you have a 10-year sealed battery model.
· Regularly clean your alarm with a damp (not wet) towel on the exterior and gently vacuum away any dust or cobwebs that might affect performance.
· Replace your alarms every 10 years. Even if they seem to work fine, fire alarm sensors degrade and lose sensitivity over time.
Skipping maintenance might seem harmless until an alarm fails when you need it most. A few minutes of upkeep and annual reminders can make all the difference.
Simple Steps for a Safer Home
You never expect a fire in your own home, but being prepared can make all the difference. Smoke alarms are essential to fire safety, but only if installed and maintained correctly. Take a moment to check yours – it’s a small effort that could save lives.
