Smoke vents is a hotly debated topic.
They have been required by the building codes for some time without any consideration of their impact on sprinklers. Even though their requirement for sprinklered facilities originally had no technical basis, their mere historical longevity provides their basis. As it turns out, full scale testing has shown they can definitely be detrimental to ESFR systems. They are detrimental because they prematurely release heat interfering with the activation of the sprinklers. The use of vents for standard sprinkler systems is also questionable.
