Subject: Sprinklers under duct

I seem to be drawing a blank and also can not find it in the standard, so if
someone can tell me off the top of their head, I'd appreciate it.
Are standard spray sprinklers located under obstructions greater than 4'
required to be included in calculations?  I seem to remember, no they are
not, however the reference in the standard is eluding me.

Thanks,
Jamie Seidl
