Why Is My Carbon Monoxide Detector Beeping?

There’s a piece of equipment inside your home that can literally be a lifesaver, but it can also drive you crazy at times – any guesses as to what it could be? That’s right, it’s your carbon monoxide detector. It’s the little thing that alerts you when that colorless, odorless, tasteless gas is detected in the air. But if you’ve ever heard it beep, you know what we mean we say “it can drive you crazy at times.” See below to find out what’s causing your CO detector to beep:

Four-Beep Alarm

If you notice a four short, but continuous beep pattern, it likely means your alarm has detected an carbon monoxide in the air. If this is the case, you should get everyone out of the house right away and call the local fire department. If anyone is suffering from even mild signs of CO exposure – headaches, nausea or vomiting – contact a physician.


There are a few reasons why your detector might chirp with a consistent pattern:

  • It’s coming up on the end of its lifespan

  • It’s letting you know the battery is low

  • The alarm has malfunctioned and requires attention

Random Chirping

If there doesn’t seem to be any rhyme or reason with the chirping pattern it could mean the batteries are loose or were not installed properly, the smoke alarm may be dirty or that it’s picking up high levels of steam, humidity or condensation.

Continuous Squeal

This is potentially the most annoying of the scenarios and it often means the alarm has a tamper-resistant warning – meaning it has been unplugged or has disconnected from its wiring, or it could mean the alarm has malfunctioned.
