I have a project with cloud ceilings that are 80 sqft clouds with a 2-foot separation around each cloud. I have no intention of omitting the sprinklers above the clouds. I plan to locate sprinklers in each cloud, considering them obstructions greater than four feet.
Do I need to space the sprinklers in the clouds to just cover beneath the cloud? Just want to confirm that spacing doesn't need to be across the cloud ceiling when sprinklers are in different clouds. Thanks in advance. Posted anonymously for discussion. Discuss This | Submit Your Question | Subscribe

Correct (IMO), you are covering the floor space that is obstructed by the cloud ceiling. If your room is 36' wide and you have 2-15' wide clouds and 2' clear between, placing 2 pendents centered in the cloud is acceptable even though the pendents would be 17' apart and 9'-6" from each wall. The heat is expected to roll by the lower clouds and activate the upper level sprinklers.

As indicated by Dan, you have to protect the ceiling according to the occupancy and the sprinklers below your clouds as for obstructions below the ceiling sprinkler deflectors.
