Subject: Re: Residential sprinkler spray obstruction

It was added to the 2007 edition of 13R (A.6.7.7.1.5.6).  The lower  
level of protection for a 13R system doesn't impact this issue since  
it is inside the room verses unoccupied and concealed spaces.

A somewhat related proposal was accepted at the ROP meeting.  Proposal  
13-496 effective mimicked the Architectural Feature text from 13D  
whereby 18 sf of shadowed floor area is allowed.
