How Smoke Alarm Work
In the event of a fire, a smoke alarm can save your life and those of your loved ones. They are a very important means of preventing house and apartment fire fatalities by providing an early warning signal so you and your family can escape. A properly installed and maintained smoke alarm is the only thing in your home that can alert you and your family to a fire 24 hours a day, 7 days a week. Whether you're awake or asleep, a working smoke alarm is constantly on alert, scanning the air for fire and smoke.
