The FireAngel FA3322 battery-powered carbon monoxide (CO) alarm comes with a built-in sealed battery and the manufacturer tells us it will last for 10 years. It’s been designed to warn when there are low levels of CO in the air and to sound the alarm when there are dangerously high levels of the deadly gas building up. The screen shows how much CO is present and tells you when to get out. But how good is this alarm at detecting CO? To find out, we put it to the test. Read on for our verdict and review of this FireAngel CO alarm.
