Carbon Monoxide Detector Placement: A Helpful Illustrated ...

Jan 18, 2020· How Carbon Monoxide Detectors Work – Does Placement Affect Their Operation? The most important component of a carbon monoxide alarm is the sensor: this is the part of the device that actually detects the CO concentration in the room. There are basically three different types of sensors: electrochemical, metal-oxide, and colorimetric ones.

Where should I place a carbon monoxide detector? | Indoor ...

Jul 15, 2020· 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. The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Keep the detector out of the way of ...
