The best Queensland smoke alarms will give residents a stronger chance of surviving a house fire. Following the newly amended smoke alarm legislation, property managers and homeowners must be cautious when choosing smoke alarms for their property. Under the new rules, all new smoke alarms that go into the property starting January 1, 2017, must be photoelectric smoke alarms that comply with the Australian Standards 3786-2014.

The best Queensland Smoke Alarms


Unlike ionisation smoke alarms, photoelectric smoke alarms provide earlier and faster warnings – a more robust alert system that gives residents more time to evacuate during a fire emergency. The new legislation orders the installation of photoelectric smoke alarms above ionisation smoke alarms. There are significant differences between the two on the way they work.

Why are photoelectric detectors the best Queensland smoke alarms?

Photoelectric smoke alarms deliver an early warning of a fire. With the interconnected photoelectric smoke alarms, you will be alerted no matter where you are or where the fire started inside your home or property. A robust warning system and a well-practised evacuation plan can go along way in ensuring the quick escape and in saving the people during fire emergencies.


Apart from being photoelectric, the best Queensland smoke alarms for the home must be interconnected with all other alarms in the dwelling. This will ensure that when one smoke alarm detects fire, all the other alarms in the house will be triggered. If a fire starts in the kitchen, even if you’re in a room upstairs, you will be alerted about it. Using interconnected smoke alarms is required under the new Queensland Smoke Alarm Legislation.

Prioritise Fire Safety

Investing in fire alarms improves home fire safety. Not only will it secure your compliance with government mandates, but it will also give you peace of mind that your home or property is safe and sound.

Additional Features that Avoid False Warnings

The Australian Standard 3786-2014 requires that photoelectric smoke alarms must have these additional features to reduce the possibilities of false warnings.

  • Finer gauze to prevent insects from entering the chamber
  • Indicator light to quickly identify which alarm activated first (considering that alarms will soon be interconnected to each other)

Inside the photoelectric smoke alarms, there is a LED light that sends a straight beam across the chamber. There is a light sensor on the other side of the chamber. Once the smoke enters the detector, it will disrupt the light beam. The beam will then go off to scattered directions, with some of the LED lights hitting the sensor. Once the light hits the sensor, it will trigger the photoelectric smoke alarms.

Ionisation smoke alarms have two electrically charged plates with small amounts of a radioactive substance. This radioactive material ionises the air, causing the current to stream between the plates. The smoke that enters the chamber disrupts the flow of ions, which in turn slows down the current. The weak flow of current will then trigger the alarm.

Which smoke alarm gives earlier warnings?

While both types are designed to detect a fire, they are not created equal. An ionisation smoke alarm is more effective for fast-flaming fires, while the photoelectric smoke alarms work best at detecting smouldering or slow-flaming fires.

Smouldering fires are most common in the home environment, and ionisation smoke alarms are slow to catch these kinds of fire. By the time residents are alerted, excessive smoke has already spread around the house, making evacuation and rescue more challenging.

On the other hand, photoelectric smoke alarms have been proven to be more effective at giving faster and more accurate fire warnings compared to ionisation smoke alarms.

Which is more expensive?

Concerning cash, the new technology is more expensive to produce and that transfers to the end cost. But the cost becomes a secondary concern considering the safety and protection photoelectric alarms can offer residents and family.

We must be cautious when choosing the best Queensland smoke alarms because not all photoelectric smoke alarms sold in the market correspond with the standard of the new legislation. We should be mindful of hiring a smoke alarm provider who’s updated with the new rules to ensure security and compliance for the owners and tenants.
