Summary of the Article:
When a carbon monoxide (CO) alarm displays an “End” message, it means the alarm has reached the end of its life. The alarm will emit a quick beep every 30 seconds.
If your carbon monoxide alarm says “End,” it is important to 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. Opening windows and doors can help reduce the amount of carbon monoxide in the air, but the source of the gas may still be producing it.
The beeping and “End” message on a carbon monoxide detector is usually caused by a malfunctioning battery. Try reinstalling or replacing the battery and then resetting the device.
If the alarm emits a chirp every 30 seconds, it could either be an end-of-life alert or a sensor error. If the alarm chirps every 60 seconds, it indicates that the battery power is not sufficient to power the unit during a full alarm. An end-of-life or sensor error will not be resolved by changing the battery.
Carbon monoxide alarms alert you with four beeps, while smoke alarms alert you with three beeps in a row.
The carbon monoxide detector reading should be as follows: Low level: 50 PPM and less, Mid-level: Between 51 PPM and 100 PPM, High level: Greater than 101 PPM if no one is experiencing symptoms, and Dangerous level: Greater than 101 PPM if someone is experiencing symptoms.
Warning signs of carbon monoxide poisoning include symptoms such as headache, dizziness, weakness, upset stomach, vomiting, chest pain, and confusion. These symptoms are often described as “flu-like.” Breathing in a lot of CO can lead to loss of consciousness or even death.
The time it takes for carbon monoxide to air out depends on the levels present. Here is a general guideline: 50 ppm – 8 hours, 70 ppm – 1 to 4 hours, 150 ppm – 10 to 50 minutes, and 400 ppm – 4 to 15 minutes.

These symptoms are often described as “flu-like.” Breathing in a lot of CO can lead to loss of consciousness or even death. - Q: How long does it take for carbon monoxide to air out?
A: The time it takes for carbon monoxide to dissipate depends on the levels present. As a general guideline, it takes about 8 hours for 50 ppm, 1 to 4 hours for 70 ppm, 10 to 50 minutes for 150 ppm, and 4 to 15 minutes for 400 ppm.
What does end mean on carbon monoxide detector
the end-of-life
When the CO alarm displays an End. message, the alarm has reached the end-of-life. The alarm will emit a quick beep every 30 seconds.

What to do when carbon monoxide alarm says end
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.
Why is my carbon monoxide detector beeping and says end
Usually, the annoying beeping caused by a carbon monoxide detector is to alert you about a malfunctioning battery. If the old battery requires changing or it's slipped out of place, the unit will chirp. Try reinstalling the battery or replacing it, and then reset your device.

What does end of unit life mean
If the alarm emits a chirp every 30 seconds, it is either an end-of-life alert or a sensor error. If the alarm emits a chirp every 60 seconds, it indicates the battery power is not sufficient to power the unit in full alarm. An end-of-life or sensor error will not respond to a battery change.
How do I know if my carbon monoxide alarm went off
Smoke alarms alert you with three beeps in a row. Carbon monoxide alarms alert you with four beeps.
What number should my carbon monoxide detector read
Low level: 50 PPM and less. Mid-level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM if no one is experiencing symptoms. Dangerous level: Greater than 101 PPM if someone is experiencing symptoms.
What are two warning signs of carbon monoxide poisoning
What are the symptoms of CO poisoning 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.

How long does it take for carbon monoxide to set off alarm
The detectors are designed to protect against acute high levels of carbon monoxide. They are NOT required to warn of low-levels of CO. The UL standard requires detectors to alarm within 90 minutes when exposed to 100 ppm; 35 minutes when exposed to 200 ppm and 15 minutes when exposed to 400 ppm.
Should my carbon monoxide detector read 0
0-9 ppm CO: no health risk; normal CO levels in air. 10-29 ppm CO: problems over long-term exposure; chronic problems such as headaches, nausea. 30-35 ppm CO: flu-like symptoms begin to develop, especially among the young and the elderly.
What number is bad for carbon monoxide
As CO levels increase and remain above 70 ppm, symptoms become more noticeable and can include headache, fatigue and nausea. At sustained CO concentrations above 150 to 200 ppm, disorientation, unconsciousness, and death are possible.
How long does it take to show signs of carbon monoxide poisoning
You may lose balance, vision and memory and even consciousness. This can happen within 2 hours if there's a lot of carbon monoxide in the air. The smaller an animal or person is, the faster they'll be affected. Pets are often the first to show symptoms.
What are the signs of a carbon monoxide leak
Signs of a carbon monoxide leak in your house or home
Stale, stuffy, or smelly air, like the smell of something burning or overheating. Soot, smoke, fumes, or back-draft in the house from a chimney, fireplace, or other fuel burning equipment. The lack of an upward draft in chimney flue. Fallen soot in fireplaces.
Will opening windows get rid of carbon monoxide
Opening windows does not provide enough ventilation to be protective. CO is an invisible, odorless gas that can be fatal. If you breathe in a lot of CO gas, it can make you pass out or kill you. People who are sleeping or drunk can die from CO poisoning before they have symptoms.
How long does it take for carbon monoxide alarm to stop
Since an alarm measures the amount of carbon monoxide over a certain period, it could take your detector hours to go off or 10 or 20 minutes if you have a lot of gas building up in your home.
Does opening windows get rid of carbon monoxide
Opening windows does not provide enough ventilation to be protective. CO is an invisible, odorless gas that can be fatal. If you breathe in a lot of CO gas, it can make you pass out or kill you.
Is it safe if carbon monoxide alarm goes off
If your carbon monoxide alarm is beeping, immediately get out of the building and call the relevant helpline for the fuel type: gas emergency helpline 0800 111 999, coal emergency helpline 08456 014 406, or oil emergency helpline 08456 585 080. Call a registered engineer to check all your fuel-burning appliances.
What is a bad carbon monoxide number
Low level: 50 PPM and less. Mid-level: Between 51 PPM and 100 PPM. High level: Greater than 101 PPM if no one is experiencing symptoms. Dangerous level: Greater than 101 PPM if someone is experiencing symptoms.
At what level will a CO detector go off
The CO alarm sounds if your sensor detects a buildup of carbon monoxide in your home—usually before you start sensing symptoms. With a low CO level (50 ppm), it may take up to eight hours for the alarm to go off. Higher carbon monoxide levels (over 150 ppm) can trigger an alarm within minutes.
What does slow carbon monoxide poisoning feel like
A tension-type headache is the most common symptom of mild carbon monoxide poisoning. Other symptoms include: dizziness. nausea (feeling sick) and vomiting.
How do I know if my house is full of carbon monoxide
The easiest way to see if there is carbon monoxide inside your home is with a carbon monoxide detector (which also includes an alarm). In fact, many building codes require a carbon monoxide gas detector.
