It is important to test your detectors monthly to ensure they are working properly. To test your CO alarms, press and hold the test button on the alarm. The detector will sound 4 beeps, a pause, then 4 beeps for 5-6 seconds.
On First Alert carbon monoxide alarms, the red light flashes to show the CO alarm is properly receiving battery power. If you do not see the red light flashing, change the batteries in the alarm immediately.
If your carbon monoxide detector is more than 5 years old, it's time to replace it. But if not, here's what you need to know about how your detector works and how to test to be sure that it's working at all.
In others, a steady or blinking green light on a carbon monoxide detector can mean it's detected a** low-level presence of carbon monoxide**. If the presence increased, it would cause the alarm to sound. It could also mean it's time to replace the battery, especially if it's also chirping.
Purchase a CO testing kit at your local Lowes, Home Depot, or on Amazon.com. Use the included canister of CO to spray onto your carbon monoxide detector. Be patient. It sometimes takes up to 30 minutes from exposure to CO for the alarm to sound.
If the carbon monoxide concentration in the air is much higher, signs of poisoning may occur within 1-2 hours. A very high carbon monoxide concentration can even kill an exposed individual within 5 minutes.
Most people with a mild exposure to carbon monoxide experience headaches, fatigue, and nausea. Unfortunately, the symptoms are easily overlooked because they are often flu-like. Medium exposure can cause you to experience a throbbing headache, drowsiness, disorientation, and an accelerated heart rate.
Luckily, if your First Alert carbon monoxide alarm is holding a steady red light, this means that it is operating normally.
Any fuel-burning appliance that is malfunctioning or improperly installed. Furnaces, gas range/stove, gas clothes dryer, water heater, portable fuel-burning space heaters, fireplaces, generators and wood burning stoves. Vehicles, generators and other combustion engines running in an attached garage.
Ultimately, no, a carbon monoxide detector cannot detect a natural gas leak. Carbon monoxide (CO) is a toxic gas created when fuel is burned in the presence of low levels of oxygen. Carbon monoxide is very different from methane and cannot be detected with the same sensor.
Your alarm manufacturer may have included a blinking red light to let you know it's time to test the alarm again. The Batteries are Low: Usually accompanied by a loud beep, a blinking red light could mean the batteries in the unit are low. Consider adding fresh batteries and running a test to make sure it's working.
A carbon monoxide alarm should be installed on every floor of a home, including the basement and near sleeping areas. It should also be installed near or over an attached garage at least 5 feet off the floor or on the ceiling.
Opening a window will slow carbon monoxide poisoning, but it likely won't stop it. There simply isn't enough airflow through most windows to get rid of the poisonous gas, and it could take between four and eight hours for the CO to dissipate entirely.
A solid green light on your smoke detector indicates that the device is on and operating normally.
Carbon Monoxide Alarm Indicators
In general, a steady or blinking green light isn't a cause for concern as long as the carbon monoxide alarm isn't chirping as well.
Carbon monoxide (CO) poisoning can become deadly in a matter of minutes. If you suspect CO poisoning, leave your home or building immediately and call 911 or go to the emergency room. If treated quickly, the effects of CO poisoning can be reversed.
For those who survive, recovery is slow. How well a person does depends on the amount and length of exposure to the carbon monoxide. Permanent brain damage may occur. If the person still has impaired mental ability after 2 weeks, the chance of a complete recovery is worse.
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.
Here's a simple guide: 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.
