12 reactions | Is there a beep or chirp coming out of your smoke alarm? Learn the sounds of your smoke alarm to know what you need to do to protect yourself, your home and your family. If you hear a beep, get on your feet! Get out, stay out and call 9-1-1 from outside. If you hear a chirp, make a change! A chirping alarm means replace the batteries or the entire unit if it's more than 10 years old. #FirePreventionWeek | Miami-Dade Fire Rescue | Facebook
