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.

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.
How to test your carbon monoxide detector to ensure they are working properly? 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.
A carbon monoxide detector is a must for any home and just as important as a smoke detector. CO detectors should be placed near all bedrooms; they're the only way you will know if carbon monoxide is affecting the air quality in your home, and can help prevent serious illness and even death.
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.
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.
Luckily, if your First Alert carbon monoxide alarm is holding a steady red light, this means that it is operating normally. However, I do understand the uncertainty since red lights typically indicate that something is wrong.
Battery and electrical power smoke detectors will usually have a steady green light to let you know the detector has electrical power and is in working order.
What does it mean? This is the power indicator light: First Alert and BRK alarms have a power indicator light to show you that your alarm is receiving power. Some alarms have a red or green light that blinks every few minutes, while other models blink rapidly or shine a solid light.
For example, some First Alert detectors use white light to indicate that the device is working. In other cases, a flashing (or solid) light with no alarm could mean it's detected a low level of carbon monoxide. If it were to reach a dangerous level, that's when the alarm would begin to sound.
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.
Will a carbon monoxide detector detect a gas leak? Technically speaking, a carbon monoxide detector is not designed to detect the presence of gas. Instead, these devices alert for elevated levels of carbon monoxide in the air that could be the result of toxic gases or air quality issues.
The most common source of CO poisoning is unvented space heaters in the home. An unvented space heater uses combustible fuel and indoor air for the heating process. It vents the gases it makes into the room, instead of outdoors.
Carbon Monoxide Sources in the Home
Clothes dryers. Water heaters. Furnaces or boilers. Fireplaces, both gas and wood burning.
Carbon monoxide is a gas that has no odor, color or taste. You wouldn't be able to see or smell it, but it can be very dangerous to your health and even fatal.
Self Checks/At-Home Testing
There isn't a self-diagnosis option for carbon monoxide poisoning, but anyone with confusion or a loss of consciousness should have 911 called for them.
BLUE/CO: Blue light flashes rapidly when sensor detects elevated CO levels.
For most residential smoke detectors, blinks are common; you need to be conversant with the colors showing. Different smoke alarms use the green and red LED to indicate the device's power status such that a flashing green means low battery while a constant blink means AC power is connected.
