What is the minimum height for placement of a CO alarm (carbon monoxide detector)?
Wednesday, January 8, 2020
A CO alarm can be installed anywhere on the wall between 6-inches above the floor to 6-inches below the ceiling, or on the ceiling except within 6-inches of the wall. There are two reasons for this:
1) Although carbon monoxide is slightly lighter than air, it mixes easily into the air and circulates at all levels, so height above the floor is not an issue, except that...
2) The requirement to keep it away from corners is to avoid the “dead space” at corners that does not get adequate air circulation.
CO alarms should be installed in the area immediately outside of all bedrooms and on each floor of a multilevel house. Also, place the alarms at least 5 to 15 feet away from fuel-burning appliances.
If you plan on using Combo CO/Smoke alarms, like the one shown at the top of the page, to comply with CO alarm requirements, they should be placed to the specs for smoke alarms, as shown below.
