Carbon Monoxide Detector Beeping? 5 Things You Should Do Right Now

A carbon monoxide detector and alarm is designed to alert users about the unsafe level of carbon monoxide. These work through making flashing lights and noise. Nevertheless, they also make flash lights and noise under some conditions. The noise that they make was described as chirping, beeping, and squeaking.

Majority of carbon monoxide detectors make sounds a much shorter chirp and beep. The beeping noise is used for alerting you unsafe CO levels. Usually, this can be in the form of four beeps. This pattern is continuously repeatedly until the CO level drops or until pressing the mute button. If you have heard the sound from your carbon monoxide detected, don’t just ignore it and consider taking action immediately.

On contrary, the chirping sound is used for reporting some problems with the detector. It isn’t as critical as beeping alarms, yet it must be addressed. The chirping will tell you that the detector might not be function or could fail soon. This may be reporting low battery, a unit malfunction, an internal error or the end of internal sensors useful life. Taking action is important to keep you protected from the danger brought by carbon monoxide poisoning. Change the battery or try replacing the device, yet keep the carbon monoxide detector operating.

While almost all carbon monoxide detectors will sound the alarm for high level of carbon monoxide, there is not as much uniformity in terms of the chirping sounds. The carbon monoxide detectors that are non-UL listed include all low level detector you feature, every alarm in its own way. Check the user’s manual that came with your carbon monoxide detector to interpret chirping noises. Digital display is very helpful because this gives additional visual information.

But, when you heard your carbon monoxide detector beeping, what are the things you should do? In this case, take action as soon as possible. Don’t stay in your place and vacate the area being affected. You can also consider calling somebody for help to fix the issue that causes high level of carbon monoxide.

That might not be the best option though, it’s important to make sure you find the best place to install a carbon monoxide detector so that it’s effective. While smoke alarms are best placed on the ceiling, that’s not the best spot for a carbon monoxide detector. See to it that you know what type you have.

The importance of several beeping might mean other things for different kinds of detectors. If your carbon monoxide detector is low on battery, you’ll likely hear short chirps each minute. Almost all carbon monoxide detectors beep four or five times in a row about each four seconds. Never misinterpret the dangerous level of poisonous gas for a carbon monoxide detector with low battery alerts. Even if there’s no one in the property is experiencing symptoms, if there is a chance your detector signals high level of carbon monoxide, get everybody outside to get some fresh air.


Look for Carbon Monoxide Poisoning Symptoms

It should be the first thing you should prioritize. Here are the common carbon monoxide poisoning symptoms that you should look out for:

    • High level of poisoning may lead to loss of muscular coordination and consciousness
    • Vomiting and nausea
    • Chest pain
    • Rapid heartbeat
    • Low blood pressure
    • Confusion
    • Shortness of breath
    • Headaches
    • Drowsiness
    • Fatigue

They might become unresponsive or weak, so be aware of it when checking for symptoms and exiting a place. If you heard carbon monoxide detector beeping, act immediately. The more carbon monoxide you breathe in, the more likely you will face serious health consequences. The reason behind it is that the poisonous gas replaces oxygen in your blood. This could lead to long-term brain damage, death, heart damage, and organ damage.

It isn’t uncommon for some to think that they have symptoms of flu, when their life is actually in danger. Therefore, it is better to be safe through searching for fresh air once your carbon monoxide detector goes off. Take note that breathing in carbon monoxide may affect every person in a different way and when you’re unconscious, there’s a chance to get out unharmed.


Call for Emergency Services

Once you’re out of the property, contact an emergency service or local fire department. Check your family members and your guests if they made it out of your property safely.

It is always a wise idea to have an escape plan in place for fire emergencies or carbon monoxide poisoning. This will help everybody in the property be aware of what you should do and where to meet in case of an emergency.


Test Your CO Detectors on a Regular Basis

Although you had a false alarm, it is crucial to test your carbon monoxide detectors on a regular basis. For detectors plugged into an outlet, you must test these once every month. If your carbon monoxide detector is battery powered, change your batteries once a year. Typically, carbon monoxide detectors last for five to seven years before they must be replaced. Many manufacturers also recommend upgrading or replacing your CO detector after five years. If it’s time for a new device, we recommend reading our guide to the best carbon monoxide detectors.

When there’s CO leak, it is normally due to the appliance that’s damaged, installed incorrectly, or being used improperly. Carbon monoxide poisoning is more common during winter season because people keep all their windows closed and use heating appliances.
