Hear a beep? Get on your feet!


Smoke and carbon monoxide alarms in your home deliver potentially life-saving messages.

Your alarm’s sounds can signal different dangers:

  • A set of three loud continuous beeps means smoke or fire.
  • A set of four loud continuous beeps means carbon monoxide is present.
  • A single chirp – repeating every 30 to 60 seconds – means your alarm battery is low and needs to be changed. If your alarm continues to chirp after replacing the battery, that means the alarm unit needs to be replaced.

Learn more about how smoke and carbon monoxide alarms keep you safe in the latest This Is TDI podcast featuring Kelly Ransdell of the National Fire Protection Association.

“We want people to learn the sounds of fire safety,” Ransdell says.
