Thanks John,
A cursory read of the section produced a visceral response. After a little
thought, I see where they are going and am not sure they went far enough.
If suppression is to be removed from the machine room, the machine room
should be in an easily accessible location and should be protected with a
rating equivalent to the shaft without exception.

Subject: 2012 IBC Sprinkler Prohibition
Reference: 2012 IBC 3007.3.1. Is this the only section of the IBC where
sprinkler are specifically prohibited from a location? Why would they do
this? In my mind this just stirs the pot of the ol' sprinkler vs. elevator
argument.
