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 - 4 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
A: Thank you for your question. We recommend a 9V battery, which is included with the device.

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.

Only reason this is not a 5 as the battery door does not close smoothly. It is slighly misaligned. But it works.

This came with a Totally Dead Battery. Also The Door To Remove And Replace The Battery Is Extremely Hard To Open, And It Makes It Hard To Install The Battery. I Would Not Buy This Again

Battery Compartment Difficult to Open
4 out of 5 stars
ldp - 3 years ago, Verified purchaser
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.
