Reviewed

The First Alert SA300 Easy Hush Smoke Alarm – as the name suggests – is rather pleased with its easy-to-use hush button, which allows the alarm to be silenced in the case of a false alarm. But 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 and find out what happened when we put it up against four different fires. Our full review of this First Alert smoke alarm reveals all.
