Q: More clarity in the question: Using the First Alert Carbon Monoxide Alarm model CO606, plugged in the wall with a 9V battery installed, what does it mean when the unit makes a sharp and short beep, unevenly spaced by minutes?

submitted by rm - 3 years ago
  • A: Thank you for your question. This could be a number of things. Did it also flash intermittently? This unit comes with a 7 year warranty. We would need more information to further troubleshoot or replace. Please don't hesitate to reach out to us here at First Alert at 1 (800)-323-9005 to further assist.

Q: If the light inside the detector is red, does that also mean that carbon monoxide has been detected?

submitted by Carrie - 4 years ago
  • A: Thank you for your question. If alarm levels of carbon monoxide are detected. The horn sounds loudly with 4 beeps, pause, 4 beeps, pause. This sequence repeats for as long as the unit is in alarm. The LED also flashes with the same pattern as the horn.

Q: What size batteries does it require

submitted by Nana - 4 years ago

Q: Aren’t carbon monoxide detectors supposed to be placed 5 feet above the ground? If you plug this in, isn’t it too close to the floor?

submitted by Luvmybabies - 4 years ago
  • A: Thank you for your question. Although there is a myth that carbon monoxide is heavier than air, it's actually slightly lighter than air and it diffuses throughout the room/house evenly. According to a peer-reviewed study published in the Journal of Emergency Medicine, the installation height of your CO alarm doesn't affect the alarm's performance. When you decide where to install a carbon monoxide alarm, choose a location where the alarm will stay clean and out of the way of children or pets.

    Do not recommend this product as it is malfunctioning. I just bought two of them and they are both making short beeps once every minute. I checked and made sure the battery it came with was secure and in place. Hopefully they will return it without the boxes.

    Battery Compartment Difficult to Open

    Just opened the package. Struggled to open battery compartment. There is a lengthy sheet of directions included, but something much shorter with just basic information would be a lot more useful.

    If my power goes out, my furnace won’t be coming on. If you do not put a battery inside, it will beep. This means it will also beep when I have to change said battery that I do not need, making it one more thing I have to do. I’m returning it and ordering the model without battery backup.
