What to Do During Daylight Saving Time Changes
• Test Every Alarm: Press the test button on each smoke and carbon monoxide detector monthly or during the clock change to make sure the audio signal works.
• Replace Standard Batteries: Change out traditional replaceable batteries (such as 9-volt batteries) in your smoke alarms at least once a year, or twice a year during the spring and fall time changes.
• Check 10-Year Sealed Alarms: If your smoke alarm uses a non-replaceable 10-year lithium battery, you do not need to change the battery, but you should still test the unit.
• Check the Manufacture Date: Look at the back of the smoke alarm unit. Replace the entire alarm every 10 years from the date of manufacture, as sensors degrade over time.
• Review Placement: Ensure you have working alarms installed on every level of your home, inside every bedroom, and outside every sleeping area.
