Daylight savings time is here again and the Bismarck Fire Department reminds residents: Is your smoke alarm still working? A smoke alarm with a dead or missing battery is the same as having no smoke alarm at all. A smoke alarm only works when it is properly installed and regularly tested. Follow these tips to maintain your smoke alarms and keep your family safe.
Smoke alarm powered by a nine-volt battery
Smoke alarm powered by a 10-year lithium (or “long-life”) battery
Smoke alarm that is hardwired into your home's electrical system
Modern smoke alarms will emit a ‘chirp’ that will indicate a low battery or the end of service life.
