The FireAngel FA3313 is a battery-powered carbon monoxide (CO) alarm. It comes with two AA batteries included and FireAngel tells us they should last for a year. When the alarm beeps every minute and the LED flashes amber, that’s the time to replace the batteries. You won’t find a screen on this model, but that’s not the end of the world if it can reliably detect CO and sound the alarm. To find out how well it works, we put it through our tests. Keep reading for our expert review and the results of this FireAngel CO alarm.

Carbon monoxide (CO) detection

How we test carbon monoxide (co) detection

Five stars means that the CO alarm detected CO in every one of our tests. One star means that the alarm failed to detect CO in one or more of our CO detection tests. We test each carbon monoxide (CO) alarm more than 30 times to see whether it can detect the deadly gas. We test with low concentrations of CO and higher concentrations. We also test with a catastrophically high concentration of the gas. We check whether the alarms respond in time and whether after detecting CO, they can go on to continue to detect the gas.
