4 Warning Sounds Carbon Monoxide Detectors Make & What They Mean

Whenever your carbon monoxide detector starts making loud sounds, here’s what you need to listen for and do in response.

Four-Beep Alarm

If you notice four quick, short beeps continuing in a pattern, it likely means your alarm has detected carbon monoxide in the air.

When you hear this alarm:

  • Get everyone out of the house right away.
  • Call the local fire department.
  • See a doctor ASAP if anyone starts experiencing signs of CO exposure, like headaches, nausea, or vomiting.

Chirping

Your Guide to Carbon Monoxide Detector Warning SoundsYour CO detector will consistently chirp when:

  • It’s approaching the end of its life span.

  • The battery is low, and it’s time to replace it.

  • The alarm has malfunctioned and requires attention, like professional electrical service.

Random Chirping

If there doesn’t seem to be any rhyme or reason to the chirping sound coming from your carbon monoxide detector, that could mean:

  • The batteries are loose or were not installed properly.
  • The detector may be dirty or sensing high levels of steam, humidity, or condensation.

Continuous Squeal

This is potentially the most annoying sound carbon monoxide detectors make. It often means the alarm has a tamper-resistant warning and:

  • It has been unplugged or disconnected from its wiring.
  • It has malfunctioned.
