The FireHawk CO7B-10Y carbon monoxide (CO) alarm fits in the palm of your hand, making it more compact than many others. There are LEDS to indicate when it’s working and when it isn’t, and it’s powered by a 10-year sealed battery, so the sensors should be good to detect CO for around a decade. It comes with a 10-year warranty, too. You can download data from the alarm to a smartphone via the Firehawk app, so notifications of any CO incidents will appear on your phone. And we like its stand - you can attach it to the wall or stand it up on a shelf. We tested this alarm to find out how responsive it was to the presence of CO in the air. Read on for our full review and test results for this Firehawk 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.
