Decoding Carbon Monoxide Alarm Signals: A Life-Saving Guide
Understanding carbon monoxide alarm sounds can save lives. Here's what each signal means and how to react.

Understanding the sounds of your carbon monoxide (CO) alarm can be a vital factor in protecting your household from danger. Knowing how to respond at the right moment can save lives and prevent property damage. Each sound from a CO alarm conveys a specific message, and it’s important for all residents of Owatonna to understand their significance.
Four Loud Beeps: If your CO alarm emits a continuous series of four loud beeps, it indicates that carbon monoxide is present in your home—a potentially deadly situation. In such cases, evacuate the premises immediately, call 911, and remain outside until emergency responders give the all-clear.
Single Chirp Every 30-60 Seconds: This sound typically means the battery needs to be replaced. Even if your alarm is hardwired, it likely has a backup battery that may need changing.
Continuous Chirping Post Battery Replacement: If the chirping persists even after replacing the battery, it suggests that the alarm has reached the end of its lifespan. Given that CO alarms should be replaced every seven years, this is a critical maintenance point—consider replacing the entire unit if you're unsure of its age.
Ensuring the functionality of CO alarms through regular maintenance can vastly improve the safety of your home. Regular checks and replacements are not only recommended but necessary. Engaging with this proactive approach is an investment in your household’s security.
Understanding these signals and their implications can and will make a difference. Let’s keep our community safe by spreading awareness and ensuring thorough preparedness.
