The short answer is that the placement height of carbon monoxide detectors does not matter because carbon monoxide spreads evenly ceiling middle floor throughout the air in a home.
Does a carbon monoxide detector work on the ceiling.

How do carbon monoxide detectors work.
Carbon monoxide often won t rise all the way up to the ceiling like smoke does until the concentration of the gas is at a critically dangerous level.
Because heat and the corresponding gases generally rise to the top of a room carbon monoxide detectors should not be placed near a floor as they will be far less likely to detect the dangerous.
Contrary to popular belief that co is heavier than air co alarms can be placed on the wall or the ceiling and will be just as effective.
Therefore it concentrates low to the floor.
Keep the detector out of the way of pets and children.
Different sensors set off different types of alerts.
A gel changes color when it absorbs carbon monoxide and this color change triggers the alarm.
The detector may be placed on the ceiling.
Carbon monoxide is a toxic gas that you can t perceive without a device.
Because carbon monoxide is slightly lighter than air and also because it may be found with warm rising air detectors should be placed on a wall about 5 feet above the floor.
In fact carbon monoxide is slightly lighter than air and diffuses evenly throughout the room.
Because carbon monoxide is slightly lighter than air and also because it may be found with warm rising air detectors should be placed on a wall about 5 feet above the floor.
According to safety experts families are not safe when carbon monoxide units are mounted lower than seven inches from the ceiling.
