Carbon Monoxide Detector Beeping: Safety Steps & Troubleshooting
If your carbon monoxide detector is beeping continuously (usually 4 loud beeps), it indicates dangerous levels of carbon monoxide. Evacuate your home immediately and call 911. If the alarm is chirping intermittently (every 30-60 seconds), it likely signals a low battery or end-of-life warning.
Why is my carbon monoxide detector beeping?
A carbon monoxide (CO) detector beeps to alert you to one of three things: the presence of dangerous gas, a low battery, or an end-of-life malfunction. Understanding the specific sound pattern is critical for your safety.
4 Beeps (Emergency)
A pattern of four loud beeps, a pause, and four more beeps generally means carbon monoxide has been detected. This is a life-threatening emergency. Carbon monoxide is an odorless, colorless gas that can cause dizziness, unconsciousness, and death.
Intermittent Chirps (Maintenance)
A single chirp every 30 to 60 seconds usually indicates a maintenance issue, such as:
- Low Battery: The most common cause for chirping. Replacing the battery usually fixes this.
- End of Life: Detectors typically last 5–7 years. If replacing the battery doesn't stop the chirping, the unit likely needs to be replaced.
- Malfunction: Dust, debris, or humidity can cause error codes or erratic beeping.
Steps to Take When Your Detector Beeps
Reacting quickly and calmly to a carbon monoxide alarm going off can save lives. Follow these immediate steps:
- Evacuate Immediately: Do not try to find the source of the leak yourself. Get everyone, including pets, into fresh air immediately.
- Check for Symptoms: Look for signs of CO poisoning, such as headaches, dizziness, nausea, or confusion.
- Call 911: Once you are safely outside, call emergency services.
- Do Not Re-enter: Stay outside until emergency responders declare the home safe.
- Inspect & Repair: Once cleared, hire a professional to inspect fuel-burning appliances (furnace, water heater, stove) to fix the leak.
Maintaining Your Carbon Monoxide Detector
Regular maintenance ensures your detector works when you need it most.
- Test Monthly: Press the "Test" button on your unit to ensure the siren works.
- Change Batteries Annually: Replace batteries at least once a year, or immediately if the unit starts chirping.
- Clean Regularly: Gently vacuum the unit to remove dust that might block sensors.
- Replace Every 5-7 Years: Check the date of manufacture on the back of the alarm. If it's expired, replace the entire unit immediately.

Carbon Monoxide Detector Beeping FAQs
If your carbon monoxide detector is beeping, evacuate the home immediately, call 911 or emergency services, and do not re-enter until the area is declared safe.
Most carbon monoxide alarms emit four loud, consistent beeps, followed by a pause, indicating dangerous CO levels are present.
Four beeps in a repeating pattern typically means carbon monoxide is detected and immediate action is required.
False alarms can be caused by humidity, steam, strong chemical fumes, or placing the detector near fuel-burning appliances with minor exhaust leaks.
Early signs include headache and dizziness, which may be followed by nausea, confusion, or shortness of breath with continued exposure.
