Looking For Smoke Alarm Installation?
Types of Smoke Alarms
When it comes to safeguarding your home from fire hazards, selecting the right type of smoke alarm is paramount. Let’s dive into the different types available and their unique features:
Ionisation Smoke Alarms
These alarms monitor “ions” or electrically charged particles. When smoke enters the chamber, it disrupts the flow of ions, thus triggering the alarm.
Ionisation alarms are generally more responsive to flaming fires. See source.
Flaming fires that spread rapidly. Research shows they detect these types of fires marginally faster than photoelectric alarms. Due to the nature of home fires, which mostly start as smouldering fire, these alarms are no longer suitable for use in Queensland homes. See this info sheet by the Queensland Fire And Emergency Service.
Photoelectric Smoke Alarms
Utilising a beam of light and a light sensor, the alarm is triggered when smoke particles scatter the light beam, reducing the amount of light that reaches the sensor.
Smoldering fires, which can burn for hours before bursting into flames. They are significantly quicker at detecting these types of fires compared to ionization alarms
Ideal for installation near kitchens and bathrooms to reduce nuisance alarms. Less prone to false alarms than ionization alarms
Dual Sensor Smoke Alarms
The laws in Queensland state:
Smoke alarms in all dwellings must:
i) be photoelectric (AS 3786-2014); and
ii) not also contain an ionisation sensor…
See this info sheet by the Queensland Fire And Emergency Service.
Provides protection by detecting both fast-flaming and smoldering fires efficiently.
These alarms do not comply with Queensland standards.

Selecting the Right Locations for Installation
Selecting the right locations for your smoke alarm installation is not just about compliance; it’s about maximising safety and ensuring peace of mind. Let’s break this down into manageable chunks, shall we?
Key Areas for Smoke Alarm Installation:
- Install a smoke alarm inside every bedroom and outside each sleeping area to catch fires where they’re most likely to break out while you’re asleep.
- Ensuring there’s at least one smoke alarm on every floor level provides a safety net, creating an early warning system throughout your home.
- Keep smoke alarms at least 3 meters away from cooking appliances to minimise those annoying false alarms when you’re just trying to cook dinner.
- Avoid placing alarms near windows, doors, or ducts where drafts could interfere with their operation. You want your smoke alarm to detect smoke, not get confused by a gust of wind.
- According to QFES guidelines, smoke alarms must not be placed:
i) within 300mm of a corner of a ceiling and a wall;
ii) within 300mm of a light fitting;
iii) within 400mm of an air-conditioning vent; or
iv) within 400mm of the blades of a ceiling fan.
This picture below is provides by the Queensland Fire And Emergency Service as part of their info sheet.
Optimal Placement Tips:
- For wall-mounted alarms, keep them not more than 30 centimeters away from the ceiling. If you’re opting for ceiling-mounted, place them at least 4 inches from the nearest wall. Why? Smoke rises, and you want your alarms to catch it as soon as possible
- In areas like the basement, install the smoke alarm at the bottom of the stairs leading to the next level. This strategic placement helps in detecting smoke as it travels upwards
- For homes with smokers or where electrical appliances are operated in sleeping areas, additional smoke alarms in these areas could provide extra safety
- In larger homes, more smoke alarms may be necessary to ensure complete coverage. Don’t skimp on safety; it’s always better to have more protection
Installation Do's & Dont's:
- Create a detailed floor plan of your property to determine the optimal locations for smoke alarms. This plan should include all rooms, hallways, and potential hazard areas, ensuring all spaces are adequately covered
- Install smoke alarms near corners where dead air might prevent smoke from reaching the alarms. Also, avoid placing them near strong drafts that could disperse smoke, hindering detection
Remember, the goal is to install smoke alarms in a way that maximises their effectiveness in alerting you to danger. By following these guidelines, you’re taking a significant step towards protecting your home and loved ones from the risks of fire.
Installation Process:
Ready to get your smoke alarms up and running? Here’s a breakdown of the installation process that’ll help you ensure your smoke alarm system is set up correctly and efficiently.
Choosing Your Smoke Alarm Type
Interconnecting your smoke alarms is a bit like creating a team where each player knows exactly when to spring into action, ensuring that no corner of your home is left unprotected. Let’s break down the essentials:
Battery
|
Ideal for those who prefer a straightforward installation without the need for wiring. Simply:
- Use the mounting base to mark screw holes on the ceiling.
- Drill holes using a bit slightly smaller than the wall anchors for a snug fit.
- Tap the anchors into place, partially screw in, align the base, and secure it by tightening the screws. Finally, attach the smoke alarm to the mounted base
Hardwired

Maintaining Your Smoke Alarms
Interconnecting your smoke alarms is a bit like creating a team where each player knows exactly when to spring into action, ensuring that no corner of your home is left unprotected. Let’s break down the essentials:
Monthly Testing & Cleaning
Press the test button on each smoke alarm at least once a month to ensure they are working correctly. It’s a quick check that can save lives.
Look for any signs of damage or obstruction that could impair the alarm’s function. This includes checking for dust build-up or physical damage
Use a vacuum with a brush attachment to gently clean the outside vents of your smoke alarm. This helps to remove dust, cobwebs, and other particles that could hinder the smoke detection process. Do this at least once a year, or more frequently if you notice visible dust accumulation
Battery Maintenance
For alarms with replaceable batteries, change them at least once a year, or immediately if the low-battery warning chirps. Smoke alarms with non-replaceable 10-year batteries should remain effective for up to a decade, but always replace the alarm itself before the battery dies.
Ensure you follow the manufacturer’s instructions for the specific brand and model when replacing batteries. Using the correct battery type is essential for the alarm’s optimal performance.
Smoke Alarm Replacement
All smoke alarms have a lifespan, typically 10 years from the date of manufacture. After this period, their sensors can become less sensitive, making them less effective at detecting smoke.
Establish a regular schedule for replacing your smoke alarms. This could be every 8-10 years, depending on the manufacturer’s recommendations. Don’t wait for an alarm to fail before replacing it.
Keep detailed records of maintenance activities, including testing, battery replacements, and the dates of alarm replacements. This helps ensure that no alarm goes without necessary upkeep
By adhering to these maintenance guidelines, you can significantly enhance the reliability and effectiveness of your smoke alarms, ensuring they are ready to alert you in the event of a fire. Remember, a well-maintained smoke alarm is a key component of your home’s safety strategy.
