Daylight savings time is here again and the Bismarck Fire Department asks 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
• Test the alarm monthly.
• Replace the batteries at least once every year.
• Replace the entire smoke alarm every 10 years.
Smoke alarm powered by a 10-year lithium (or “long-life”) battery
• Since you cannot (and should not) replace the lithium battery, replace the entire smoke alarm according to the manufacturer’s instructions.
Smoke alarm that is hardwired into your home’s electrical system
• Replace the backup battery at least once every year.
Modern smoke alarms will emit a ‘chirp’ that will indicate a low battery or the end of service life.
