This Weekend, Change Your Clock Back One Hour and Check Your Smoke Alarm

Posted at 2 p.m.

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.

On Sunday, Nov. 6 when resetting your clocks for Daylight Saving Time, make sure your smoke alarms work and replace the batteries, if necessary. Take care of your smoke alarms according to the manufacturer’s instructions, and follow these tips from the U.S. Fire Administration (USFA):

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

  • Test the alarm monthly.
  • 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

  • Test the alarm monthly.
  • Replace the backup battery at least once every year.
  • Replace the entire smoke alarm every 10 years.

Test smoke alarms monthly and replace alkaline batteries at least once each year. Most home fire deaths happen when people are asleep (between 11 p.m. and 7 a.m.). Keep your family safe by installing smoke alarms and testing them monthly to make sure they work.

    Thank you for the usual reminder. This is also the semi-annual reminder/opportunity to review & practice your family (& next door) disaster plan & refurbish your home, car, & office disaster kits for winter. We took a mini-disaster vacation week-end, catching up with our out of state emergency contacts, rotate meds, & ‘testing’ the supplies before they pass their ‘use by’ date. The trees are turning beautifully, reminding us that change is inevitable & preparation can make it invigorating.
