Intent

Intent 1:

To exempt certain ducts or air-transfer openings from the application of Sentence 3.1.8.7.(1), which would otherwise require fire dampers, on the basis that the installation of fire dampers in this case would lead to a higher level of fire-resistance at the fire damper location than that provided by the fire separation.
