I would check or change the batteries in the alarm and see if it happens again. Also perhaps get a new carbon monoxide alarm just be sure.
This could be due to a faulty device, old batteries, or just dust buildup in the unit itself. It's better to be safe than sorry. If your alarm sounds, it's important to call emergency responders. They can tell you if you're experiencing a false alarm.
Call 911 immediately and report that the alarm has gone off. Do not assume it is safe to reenter the home when the alarm stops. When you open windows and doors, it helps diminish the amount of carbon monoxide in the air, but the source may still be producing the gas.
Call for Help: If you cannot identify a simple reason for the alarm (like a low battery) or if you suspect elevated levels of CO, call emergency services or the fire department immediately.
Here are some of the reasons, however, refer to your product's manual for your specific model: The detector has a low battery and they need to be replaced. The detector has reached its end-of-life and the alarm itself needs to be replaced. Elevated levels of carbon monoxide gas have been detected.
The most common symptoms of CO poisoning are headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. CO symptoms are often described as “flu-like.” If you breathe in a lot of CO, it can make you pass out or kill you.
If your CO detector goes off and you feel ill, leave the house and call 911 or the local fire department. If you do not feel ill, push your detector's reset button. If the alarm goes off again after a few minutes, open the windows, leave the house and call 911 or the local fire department.
The best way to alert you and your family to unsafe levels of CO is to install a carbon monoxide detector. It works like a smoke alarm, sampling the air in your home and creating a loud alarm when levels of the gas are detected. It's important to evacuate your home immediately when your CO alarm sounds.
In most areas, the fire department does not charge to respond to carbon monoxide alarms or to check for the presence of CO in a residence. However, policies can vary depending on the jurisdiction or specific fire department. It's always a good idea to contact your local fire department for specifics on their policies.
If your CO alarm stopped beeping after being outside in the fresh air for 10 minutes, you may have a possible carbon monoxide leak in your home. We recommend calling your gas supplier or national emergency gas helpline on 0800 111 999 and await further instruction.
If your detectors go off, call 911 and evacuate the home. Be sure to notify them if anyone in the house is experiencing flu-like symptoms. The Fire Department has specialized equipment to detect and measure amounts of CO in your home.
Your carbon monoxide alarm is going off for one of the following reasons: It is doing its job properly and detects CO pollution in the air. It is a false alarm caused by other household items. The detector is malfunctioning or the batteries need changing.
Any fuel-burning appliance that is malfunctioning or improperly installed. Furnaces, gas ranges or stoves, gas clothes dryers, water heaters, portable fuel-burning space heaters, fireplaces, generators, and wood burning stoves. Vehicles, generators, and other combustion engines running in an attached garage.
It can take a standard carbon monoxide detector one hour to alert at concentrations of 70 ppm and below. CO detectors will respond to extremely high concentrations of 400 ppm and above in as little as four minutes.
If no one is feeling symptoms, ventilate the home with fresh air, turn off all potential sources of CO - your oil or gas furnace, gas water heater, gas range and oven, gas dryer, gas or kerosene space heater and any vehicle or small engine.
Go to the Home app on your iPhone or iPad. , then tap Home Settings. Tap Safety & Security. Tap Sound Recognition, then turn on Smoke & CO Alarm.
Smoke alarms alert you with three beeps in a row. Carbon monoxide alarms alert you with four beeps. A single chirp means the battery is low or the detector should be replaced.
If you have a carbon monoxide detector chirping and then it stops, it's important to take the situation seriously, even if the alarm is no longer sounding. Even if the alarm has stopped, get everyone out of the home to a place with fresh air. Contact 911 or your local fire department to report the incident.
Before you return to your home it is very important to call the 24 hour Gas Emergency Number on 0800 111 999 and tell them what has happened and receive safety advice (even if the suspected source of the CO is not a gas appliance).
If your home has a well-functioning ventilation system, the carbon monoxide should be cleared within 30 minutes. If the ventilation is inadequate, it can take several hours to clear.
The carbon monoxide alarm going off could mean the gas is present in your home or office, or simply indicating the battery or alarm needs replacing. The deadly gas is a product of partial combustion of carbon-based compounds where there is not enough oxygen to create carbon dioxide (CO2).
How to test your carbon monoxide detectors to ensure they are working properly? To test your carbon monoxide detectors, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds. Refer to the user manual for your specific model.
My carbon monoxide alarm is sounding. What should I do? Call 911 and report what is happening. Immediately leave your residence and wait for the fire department to arrive.
