A continuous or constant beep is a common sound from a carbon monoxide detector. It is the typical warning chirp and notifies you of potential danger.
Further, almost all carbon monoxide detectors produce this beep type when functioning correctly.
The first detector alert warns you to leave the room or area and stick your head outdoors for fresh air. However, sometimes the device produces three beeps.
So, let us discuss the question: 3 Beeps On a Carbon Monoxide Detector, what does it mean?
Three beeps on a carbon monoxide detector signify a malfunction with the alarm. Also, these chirps occur after every fifteen minutes, making them hard to ignore.
Therefore, contact the product manufacturer and get it checked immediately. In addition, remember that having a functional carbon monoxide alarm is advisable for enhanced safety.
The carbon monoxide detector also produces sounds like a pulsing or intermittent beep. This signal indicates dangerously high carbon monoxide levels, and it is prudent to take action.
Check out this write-up for more insight into the devices, how they relate to carbon monoxide levels, and interpret different beep types.
What Is a Carbon Monoxide Detector?
A carbon monoxide (CO) detector detects CO gas to prevent poisoning. Further, it is a simple device with a few components, such as a silicon microchip and a sensor.
A plastic shell houses the silicon microchip, which sends an electrical charge to the carbon monoxide sensor. In addition, this sensor detects high CO levels, making the microchip trigger an alarm.
Carbon Monoxide detectors also have a test button, a power indicator light, and an LCD screen.
Moreover, device models with the LCD screen display the system status and CO gas levels during an alarm.
Furthermore, the device has power indicator lights, an LCD screen, and a test button that facilitates convenient handling.
The indicator also shows whether the unit is functional or requires a battery replacement.
Some CO detector brands make a chirping noise to show low battery levels. Also, the test button comes in handy during functionality tests.
So, test the device monthly and change or replace the batteries when necessary.
Generally, carbon monoxide detector units sound an alarm after sensing certain CO levels over time. In addition, you will observe different sensors in various alert types. They include
- Biometric Sensor. This sensor features a gel that changes color after carbon monoxide absorption. Then, this hue triggers the alarm.
- Electrochemical Sensor. The electrodes in a chemical formula sense electrical current change. This scenario lowers the electrical resistance, triggering the alarm.
- Metal Oxide Semiconductor. The silica chip’s circuitry lowers electrical resistance after detecting CO, triggering the alarm.
Remember, once the carbon monoxide alarm device sounds, you need a CO-free space to silence the siren.
We have three primary carbon monoxide detector models in the market.
Further, getting the most suitable device for your facility is prudent for maximum safety and protection. The types are as follows.
- Battery-Operated Carbon Monoxide Detectors
These CO detectors are the most flexible and easiest to handle. Besides, they utilize a sensor technology that quickly detects carbon monoxide exposure.
You can install the detector anywhere and move it around since it does not depend on a fixed power source.
However, you’ll need to replace the batteries annually to guarantee enough operational energy.
- Smoke/Carbon Monoxide Dual Detectors
Interestingly, some devices are all-in-one, thus detecting detect smoke and carbon monoxide. They are ideal for space-challenged facilities or households where you want to minimize visual clutter.
In addition, most smart carbon monoxide detectors are a smoke-CO combination and successfully identify either occurrence.
- Hardwired or Plug-In Carbon Monoxide Detectors
You can wire CO detectors to the existing household current, plug them into an outlet, and expect optimal functionality.
Moreover, the devices are low maintenance as they do not use batteries. Even better, the sensor cycles itself, quickly purging and resampling for carbon monoxide.
Dangers of Carbon Monoxide Detectors Beeping
Learning why a carbon monoxide detector beeps is critical in determining the course of action. Besides, although we have various reasons for the chirps, please pay attention to them and investigate the matter.
Evacuate the facility or premises and call the fire brigade and boiler technician if the CO detector beeps for the first time.
Conversely, sometimes the unit’s alarm beeps constantly without a CO risk. Here, check why it is chirping and take the necessary action.
Most times, the issue is a simple malfunction or flat batteries. But a thorough check is advisable to guarantee it is not something more serious.
Ignoring a CO detector’s beeps may jeopardize your household, especially if the alert shows high carbon monoxide levels.
In addition, fix a faulty carbon monoxide detector as soon as possible. Otherwise, you may not detect a CO gas hazard early enough.
How to Use Carbon Monoxide Detectors Safely
The surest way to use a carbon monoxide detector safely and effectively is by following the manufacturer’s instructions. Here are a few expected guidelines.
- Keep the unit at least six feet away from a fuel or flame source. Otherwise, you will get multiple false alarms.
- Install the device at least five feet from the ground or on the ceiling. But ensure that you keep a six-inch distance from the wall.
- Drill holes and hang the mounting bracket to ensure a firm grip.
- Use new batteries for optimal efficacy.
- Test the detector by pressing and holding the test button. Also, expect to see lights and hear an alarm.
- Attach the carbon monoxide detector to the installed bracket.
Smoke and CO detectors need regular maintenance to remain operational. Also, always check the battery level by pressing the text button. This way, you can replace the batteries on time.
In addition, replace the unit’s batteries at least annually. Otherwise, they may run out, compromising the detector’s functionality.
Carbon monoxide detectors also need replacement after their life span expires. Unlike smoke detectors that give a battery-low warning sign, CO detector units start chirping when it’s time to replace them.
Fortunately, the alarms also have a long lifespan, up to five years. Therefore, you’ll enjoy their services before thinking of a reinstallation.
Further, these detectors differ from standard smoke alarms, so most people need to learn how and where to place them.
Thankfully, the Consumer Product Safety Commission gives some guidelines. For example, it recommends the unit be placed on each home level and outside sleeping areas.
In addition, have a minimum number of detectors. So, put one in the hall, allowing all bedrooms to hear the warning.
Carbon monoxide poisoning is mild and won’t wake you up. Thus, ensure each room can hear the alert.
Also, remember that the carbon monoxide detector works best at roughly five feet from the ground. Here, it measures the air at a suitable height, especially the level that people are breathing it.
Revealing carbon monoxide sources is essential in ensuring the leak does not happen again. They include fuel-burning devices and flame sources such as gas driers, vehicles, water heaters, furnaces, and fireplaces.
Sometimes, you’ll need the alarm in the kitchen. But please avoid mounting it over or near a flame-producing device such as a grill, stove, or fireplace. This way, you won’t have false alarms.
Finally, the International Association of Fire Chiefs advises homeowners to install a carbon monoxide detector in their basements. Laundry machines, furnaces, and water heaters are potential CO sources.
You can also consider the garage as vehicles are a common carbon monoxide producer.
How to Identify the Smell of Carbon Monoxide
CO is colorless with no smell, making it difficult to detect. Therefore, you’ll have to rely on carbon monoxide detectors.
In addition, exposure to high CO levels has various symptoms, such as dizziness and headaches.
Carbon monoxide originates from an incomplete process of liquid, solid, and gaseous fuels or comes from appliances fueled with oil, natural gas, kerosene, wood, coal, and liquefied petroleum.
You can also produce the gas by running a non-electric machine or burning charcoal.
Typically, small carbon monoxide amounts by home heating equipment do not build up inside as they are vented outside. But sometimes the air circulating the heating systems and rooms is not adequately vented, or there’s a leakage causing CO buildup.
As a result, you experience carbon monoxide poisoning, leading to a blockage of normal oxygen delivery to the tissues.
Further, CO is hazardous and often called a ‘silent killer, as it is hard to detect until it is too late.
In addition, although many carbon monoxide poisoning victims recover with treatment, severe cases lead to permanent brain damage.
Thankfully, we have a few signs that show a carbon monoxide leak in your home or house.
- Heavy condensation and dripping on the windows near the appliance show you’ve reduced moisture production. But it could also signify that the humidifier settings are very high.
- Brownish-yellow or sooty stains around the leaking device.
- Stuffy or stale smell, especially the odor of something overheating or burning.
- Lacking an upward draft in the chimney flue.
- Fumes, smoke, soot, or back-draft in a home from a fireplace, chimney, or fuel-burning equipment.
- Some fallen soot in the fireplace.
- The odor of unusual gases in the facility. Although CO is odorless, you may notice exhaust gases.
- Solid fuel fires combust slower than usual.
- A yellow burner flame instead of a transparent blue flame.
- A frequently blowing out the pilot light.
You must act immediately after detecting a carbon monoxide leakage. Hence, check out the above signs and CO poisoning symptoms, such as tightness around the forehead, headaches, and increased heart pounding.
Generally, the first protective measure against carbon monoxide poisoning involves inspecting the home’s heating devices annually.
These devices include chimneys, vents, and gas appliances.
Lastly, install carbon monoxide alarms on every home level and test them regularly. Also, avoid using BBQs, charcoal fuel burners, or grills in unventilated spaces.
Common Causes of Carbon Monoxide Detectors Beeping

So, get the unit for enhanced safety and guaranteed peace of mind.
Further, even in excellent conditions, fuel-burning appliances, such as water heaters, portable gas heaters, and wood-burning stoves, produce mild CO levels. Thus, placing a carbon monoxide detector too close to them triggers a false alarm.
As a result, experts recommend placing the device 15 to 20 feet away from these appliances to minimize false readings.
- Trigger Two: Humidity Sources
Exposure to high humidity and moisture sources affects the CO detector’s functionality. Also, although atmospheric moisture does not trigger the alarm, it may damage some device parts, causing a malfunction.
Please avoid placing these units in steam rooms, bathrooms, or near humidifiers. Instead, keep them at least ten feet away from humidity sources.
- Trigger Three: Hydrogen Gas
Depending on the carbon monoxide detector’s design, it may be prone to interference from other gases, such as hydrogen. The gas also messes with chemical reactions allowing the unit to do its job.
Further, lead acid batteries produce hydrogen that causes interference with the device, leading to a false alarm.
- Trigger Four: Internal Malfunction
Working with a carbon monoxide detector is unpredictable when its batteries are flat, or the unit needs replacement.
Moreover, a damaged part causes it to operate irregularly and trigger the alarm without CO presence. Thus, purchasing a new device is advisable, as fixing it is challenging.
Fortunately, the CO detectors feature a different alarm pattern to show dysfunctional parts.
So, you have nothing to worry about.
Despite a signal being a false alarm, it is advisable never to ignore it. Besides, unsafe carbon monoxide levels come from appliances needing repair, replacement, or inspection.
Thus, follow the emergency guidelines and evacuate immediately.
In addition, wait for an expert to conduct a thorough safety inspection before reentering the facility.
You can refer to the manufacturer’s manual when in doubt. It gives you specific signals from your CO detector and how to interpret them. But generally, if the unit beeps continually, the alert is false, or something needs replacement.
Below are some alert sirens and what they mean.
- Five Beeps Per Minute
This signal shows that the CO detector is old and needs replacement. Every product has a lifespan, even advanced technological products.
Thankfully, carbon monoxide detectors do not die immediately. Instead, they give the user warning before they stop working.
Therefore, invest in a good quality product to protect your facility and install it before the other dies.
- Four Beeps and a Pause
These alerts signify that the facility has high carbon monoxide levels. Therefore, move away from the room and call for emergency assistance.
- Three Beeps Every 15 Minutes
Three chirps after 15 minutes reveal that the carbon monoxide detector is incorrectly mounted or faulty. Therefore, inspect the CO device for faults and replace it with a compatible unit.
- One Beep Per Minute
This beep shows that the device’s battery is running low. Hence, the CO detector alerts you that the batteries need replacing.
However, although this occurrence is not an emergency, replace these batteries as soon as possible.
How to Reduce Carbon Monoxide and Smoke Detector False Alarms
Smoke and carbon monoxide detectors can give false alarms for various reasons. Further, nuisance or false alarms occur when the device goes off without detecting CO in the facility.
However, evacuate the building and call 911 if the CO detector sounds, even when unsure of its validity.
Still, false alarms are frustrating, especially when cooking or in the middle of the night. Therefore, consider the installation and maintenance tips below to reduce these nuisance sirens.
