Greg Are you asking if the combustible concealed sprinklers are acceptable for this scenario or are you trying to eliminate sprinklers in the space based on the metal C Channel joists. If the plywood is not FRT then this space requires protection unless it is less than 6" from top of channel to bottom of channel.. This is my opinion

However I'd be extra cautious in that assessment as you may be required to provide a minimum 3,000 ft² remote area per 11.2.3.1.5.1. quick thoughts, Ken Wagoner, SET Parsley Consulting 350 West 9th Avenue, Suite 206 Escondido, California 92025 Phone 760-745-6181 Visit the website<http://www.parsleyconsulting.com/> On 08/22/2018 1:00 PM, [email protected]<mailto:[email protected]> wrote: Am I missing something or is there not an exception for protecting comb concealed spaces with Metal C Channel joists and plywood on the top and bottom?
