A CO carbon monoxide alarm is a safety device designed to detect the presence of carbon monoxide (CO) gas in the home. Carbon monoxide is a colourless, odourless gas produced by incomplete combustion from appliances such as heaters, stoves, and fireplaces. In simple terms, a CO alarm alerts you before dangerous levels build up, keeping your family safe.
Here’s why Australians prioritise CO alarms: carbon monoxide is invisible and deadly, so a reliable alarm is an essential safety feature in every home.

CO alarms vary in technology, design, and installation methods for Australian homes.
Common Types

Plug-In CO Alarms
