As we approach the end of Daylight Savings Time on November 5, many of us will be turning our clocks back by one hour. This is also an opportune moment to take care of an essential home safety task – changing the batteries in your smoke alarms and carbon monoxide (CO) detectors. Properly functioning alarms are vital for protecting your home and family from unforeseen dangers.

Smoke Alarm Battery Maintenance

Not all smoke alarms are designed the same. Here's how to ensure their proper functioning:

• 10-year non-replaceable batteries: These alarms are meant to last up to a decade. If the alarm starts to chirp, indicating a low battery, it is time to replace the entire unit.
• Other battery types: For alarms using regular batteries, replace the battery at least once a year. If the alarm chirps warning of a low battery, replace it immediately.

Carbon Monoxide Alarms: Decoding the Beeps and Chirps

Understanding the sounds your CO alarm makes can help you respond appropriately:

• Four loud beeps (beep, beep, beep, beep): This indicates the presence of carbon monoxide in your home. Evacuate the premises, call 911, and remain outside until help arrives.
• A single chirp every 30 or 60 seconds: The battery is low and needs to be replaced. Even plugged-in alarms have a battery back-up that requires maintenance.
• End of life sounds: CO alarms will produce specific sounds when they reach the end of their lifespan, which vary by manufacturer. When you hear these distinct noises, replace the alarm.
• Continuing chirps after battery replacement: If your CO alarm is over 7 years old and still chirps after a new battery is installed, it’s time for a replacement.

By taking the time to change your clocks and replace the batteries in smoke alarms and CO detectors, you're helping ensure the safety of your home and loved ones. Stay vigilant and make these tasks a part of your fire safety routine.
