How Many Smoke Alarms Do You Need? Use Our Free QLD Calculator

Use our calculator to estimate how many smoke alarms are required in your Queensland residential property to comply with QLD 2027 regulations. The regulation mandates the installation of interconnected smoke alarms in bedrooms and hallways, as well as on every storey. However, interconnected smoke alarms are not required in public areas, laundry, or garage, although you may choose to install them in those areas for enhanced protection. Consider incorporating Activfire accredited alarms, as they meet the highest safety standards. Additionally, remember to take into account the power source for your new alarms; if you have existing 240V alarms in your property, you are obliged to upgrade those to new interconnected 240V alarms. All additional alarms can be either 240V or battery-operated and must interconnect as one system.
