Expert review

The First Alert SA300 Easy Hush Smoke Alarm comes with a 'hush' button, which allows the alarm to be silenced in the case of a false alarm. It uses replaceable batteries and isn't interlinked, so it won't be suitable for homes in Scotland when the law changes in 2022. To find out how sensitive it is to smoke from more than just burned toast – which you might need the hush button for – we tested it. Read on for the results of our smoke alarm tests for this First Alert alarm and find out what happened when we put it up against four different fires.
