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