Kidde Smoke Detectors Repair Guides

Beeping or Chirping Every 30-60 Seconds

A Kidde smoke detector that chirps every 30-60 seconds is telling you the battery is low. It's not a fire alarm — it's a low-battery warning. Replacing the battery stops it immediately. If it still chirps after a new battery, the unit itself has reached end of life (they expire after 10 years).
