Your smoke alarm should be tested once a month. Just get Mom or Dad to press the test button to see if it works.
If your smoke alarm runs on batteries, they need to be replaced at least once a year. Pick a day, any day of the year, maybe even your own birthday, and for a present, give your smoke alarm fresh juice.
Have a look around your house. You should have at least 1 working smoke alarm on every floor, and at least one outside each sleeping area.
