With the recent Queensland Government changes to smoke alarm laws, there is a lot of confusion about the difference ionisation and photoelectric smoke alarms. To help you understand the difference, our electricians have put together this helpful guide.
Ionisation smoke alarms
Ionisation smoke alarms are the most commonly known smoke alarms. These alarms are said to ‘smell’ the smoke from flames, by detecting particles of combustion. They contain trace amounts of radioactive material between two electrically charged plates, which ionises the air between the plates. When smoke disrupts this flow, the alarm is activated.
While they are great for detecting fast burning fires, they are slow to respond to slow smoulder fires (which are more common). They are also susceptible to false alarms resulting from excess dust, steam or temperature changes.
Photoelectric smoke alarms
Photoelectric smoke alarms are now recommended by the government and fire safety professionals for all Queensland homes. These alarms are said to ‘see’ smoke, rather than ‘smell’ it. These alarms contain a sensing chamber and light source. When smoke particles enter the chamber, the light source is reflected onto the sensor which then triggers the alarm.
These alarms are much more effective at detecting and responding to smouldering fires (slower burning fires that are the most common fires in homes). This gives you more time to escape your home in the event of a fire.
