Carbon monoxide is a colorless, silent killer, odorless gas that can cause serious health hazards. It’s produced by burning wood, oil, coal, and gasoline. It can be deadly if carbon monoxide builds up in an enclosed space due to poor ventilation or someone misusing flammable fuel. Installing a carbon monoxide (CO) detector or alarm in your home is the best way to protect yourself from this toxic gas.
But is it enough? Do you know what a carbon monoxide alarm sounds like? No!? Then, a CO alarm can do nothing to help you. However, you don’t need to sweat much because we got your back. We’ll look at how CO alarms work and explore the different emergency warnings they provide so that you know how to respond quickly and appropriately when they sound. So, read on.
How loud is a carbon monoxide alarm?
The detector keeps track of the air’s gas levels, usually in small amounts. It uses this information to determine if there is a potential risk of CO buildup in the body. If the levels are high enough to be concerning, the device sets off an alarm that is 85 decibels or more in volume. This alarm is loud enough to wake most people up from their sleep.
The alarm must be loud enough to ensure that it can be heard throughout your home, even if you’re in a different room or floor. The intensity of the sound is intended to grab your attention and prompt you to take immediate action in the event of a CO leak. This helps ensure your and your household’s safety by allowing you to evacuate the area and seek fresh air as soon as the alarm sounds.
Remember that the loudness of the alarm is a critical feature, as carbon monoxide is a silent and potentially deadly gas that can accumulate without any noticeable signs. Regularly testing your carbon monoxide alarm and familiarizing yourself with its sound are important steps to ensure its effectiveness in an emergency.
What Does a Carbon Monoxide Alarm Sound Like?
| Sound Pattern | Meaning |
|---|---|
| Sound-1: 3 Long Beeps | This sound is indicative of a smoke alarm. It means that the smoke alarm has detected smoke, which could potentially indicate a fire. The alarm emits three long beeps every 1.5 seconds, accompanied by a flashing red LED light. Occupants should evacuate immediately upon hearing this sound. |
| Sound-2: 4 Long Beeps and Repeating | This sound is from a carbon monoxide (CO) alarm. It signals that the CO concentration in the area has reached a level of 30 to 999 parts per million (ppm). The CO detector will flash its red LED four times during 5.8-second intervals, followed by a blue backlight. After about 4 minutes, the red LED will flash 4 times in a minute, with the alarm beeping 4 times every 5.8 seconds initially, then 4 times a minute after 4 minutes. This indicates a potentially hazardous CO level, and occupants should evacuate and contact emergency services. |
| Sound-3: 3 Chirps | This sound pattern is commonly associated with a carbon monoxide alarm indicating low battery power. Three chirps in a row serve as a reminder to replace the detector’s batteries as soon as possible. A single chirp per minute signifies a low battery requiring replacement, while five chirps per minute indicate that the battery is nearly depleted and needs immediate replacement. |
How long does a carbon monoxide alarm go off?
The duration for which a carbon monoxide (CO) alarm goes off can vary depending on the specific alarm model, the carbon monoxide detected, and the duration of exposure. When a CO alarm is triggered, it typically emits a continuous loud sound or a pattern of beeps to alert occupants of potential danger. This alarm sound serves as a warning for people to evacuate the area immediately and seek fresh air.
CO alarms are designed to remain active until the detected CO levels drop to a safe threshold or until the alarm is manually silenced. The alarm can range from a few minutes to several hours, depending on factors such as the source of the carbon monoxide, ventilation in the area, and the responsiveness of the individuals in addressing the issue.
It’s important to note that even if the alarm stops, it doesn’t necessarily mean the danger has passed. If your CO alarm goes off, you should follow the safety protocols mentioned earlier, which include leaving the premises, calling emergency services, and ensuring the area is properly ventilated before re-entering.

How do I know if my alarm is going off for carbon monoxide?
You can recognize if your carbon monoxide alarm goes off by its distinct and often loud sound. Carbon monoxide alarms are designed to emit a specific pattern of beeps or a continuous siren when they detect elevated levels of carbon monoxide gas in the air. Smoke alarms will alert you with three consecutive beeps, while carbon monoxide alarms will issue four as a warning. If you hear a single chirp, the battery is low, or the detector needs replacement.
Additionally, some advanced models might have digital displays showing carbon monoxide concentration in parts per million (ppm). If the displayed levels are rising or reaching dangerous thresholds, it’s a clear indication that there is a potential risk. Always take any carbon monoxide alarm seriously, and if it goes off, follow safety protocols by evacuating the area, seeking fresh air, and contacting emergency services to assess and address the situation.
If the carbon monoxide detector beeps, then stop:
If your carbon monoxide detector emits a beep and then stops, it’s important not to dismiss this signal. While a single beep followed by silence might not indicate an immediate threat, it could still signify a potential issue. Carbon monoxide detectors are designed to alert you to this colorless and odorless gas, which can be life-threatening at high concentrations.
