Unless you invoke section 11.1.2, in which case none of those features are required.

Additional heads flowing outside the "design room" are only applicable in light hazard where the doors are not automatic or self-closing (no rating required). In ordinary hazard rooms, there is no option, the doors must be rated and automatic or self-closing. In either hazard the walls must be rated to the duration of the water supply required.

I'm probably not understanding the issue, but that seems relevant to me from what I read in the room design paragraphs of -13. -- PARSLEY CONSULTING Ken Wagoner, SET 760.745.6181 voice 760.745.0537 fax [email protected] <mailto:[email protected]> e-mail www.ParsleyConsulting.com <http://www.ParsleyConsulting.com> website Richardson, R wrote: > It does meet 11.1.2 (subject to a massive interpretation as to what > constitutes adequate separation), but does not meet room design because the > wall is not fire rated, the doors in the wall are not self-closing and they > are not including two heads outside the OH area as required by room design. > > Rich > > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On Behalf Of Thom McMahon > Sent: Monday, March 22, 2010 10:42 > To: [email protected] > Subject: RE: Room Design vs. Adjacent Hazards > > Rich: > > How does your 600 Sf OH space not meet the requirements of 11.1.2(2)?
