Key Product Features

Carbon monoxide is a highly poisonous gas, caused by fuel not burning properly. It cannot be seen, smelt or tasted by the human senses and is only detectable through a CO alarm.

Battery powered carbon monoxide alarms can typically be installed wall-mounted or left free-standing on flat, level surface. The 7 year sealed battery powered FireAngel CO-9X carbon monoxide alarm features clear LED indicators for power, fault or alarm status and a large test/reset button for ease of testing the device. The CO detector can be wall mounted for home use, or can be left free standing, making it a suitable portable detector to take on holiday. If your CO alarm is flashing a red LED light every 20 seconds, it has been activated recently. This is referred to as ‘alarm memory’, find out more about what this feature means here. Why does my FireAngel CO alarm not sound when I press the test button? With the alarm memory function, the red LED will flash to provide a visual indication of a previous CO alarm activation.
