Carbon monoxide detectors are typically small, round, and white. They typically have two holes for mounting screws, a center button to test the device, and a digital display that shows the carbon monoxide level in the home.
Test for different beeping patterns.
Smoke alarms typically sound with 3 beeps in a row, while carbon monoxide detectors usually sound with 4 beeps.
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.
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.

Carbon monoxide is an odorless, tasteless gas that occurs when fuels aren't completely burned off. Hundreds of people die from CO poisoning every year, and almost 50,000 more become ill. Many things in the home produce CO, including your gas and oil-burning stoves and furnaces, vehicles and charcoal grills.
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.
False or nuisance alarms are when your smoke detector or CO alarm goes off, but there is no presence of smoke or carbon monoxide in your home. However, if your smoke or carbon monoxide detector sounds indicating an emergency and you are not certain it is a nuisance alarm, evacuate the home and call 9-1-1.
How can carbon monoxide build up in a home? The most common causes of carbon monoxide building up are incorrectly installed or poorly maintained or ventilated appliances – like stoves and hot water heaters. Poorly ventilated fireplaces and other gas- or wood-burning appliances can also pose danger.
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.

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.
A flashing green light is a normal part of the power up cycle. Any time there is a power outage, brownout, surge or other problem with the power, the alarm goes through a power up cycle. The flashing on your plug-in carbon monoxide alarm should stop after 5 minutes, then the light will stay a steady green.
If you experience symptoms that you think could be from CO poisoning: DO GET FRESH AIR IMMEDIATELY. Open doors and windows, turn off combustion appliances and leave the house.
