Where should a smoke detector be placed on a tray (coffered) ceiling?
Friday, December 4, 2020
A smoke alarm should be placed on the highest part of a tray-shaped (coffered) ceiling, or on the sloped part within 12 inches of the highest point, according to the National Fire Protection Association [NFPA 72, 184.108.40.206(12), 2019 edition].
Smoke rises first to the highest point of a ceiling, then moves downward as it accumulates. So a location on the lower ceiling level, like in the photo above, will take longer to respond to a fire.
