I believe what you've seen is addressing unrated Atrium openings, the wording on this is in IBC. It doesn't pretend to make a 2-hour wall out of it as Window sprinklers are listed to do.

I haven't looked up the code reference for this since I haven't had to convince someone to accept the idea; I've only seen it in the field on occasion.

I have a glass wall that I need to be fire rated and I have a contractor telling me by code he can use a pendant head instead of a deluge head or a Tyco window sprinkler. The only code I see that possibly address this is 21.20.1.2.1 and it only says you have to use automatic heads. Any help!!!!!
