Designer has clouds in halls that vary in distance below the ceiling above from 2 to 3 feet. Sprinklers are installed above and below clouds. Clouds have about a 1 -1.5 foot openings on their parimeters that opens to the ceiling above. The required smoke detection system had detectors on the bottom of the cloud. I found that sidewalls must be lower than 4 inches and max at 12 inches but these are mounted on the cloud. I called manufactureer and they said they would get back to me. What are your thoughts?
Is the detector okay on cloud?
If they are to be mounted on the ceiling above the cloud is the air between the cloud and ceiling a dead air space?
If mounted on the ceiling should the spacing be tighter since smoke would have to move some distance to get around the cloud?
