I would say that you can do 0.10 if you talk to the AHj, show twice the water of 13R, and show that it still doesn't require heads under garage door. What happens to your OH I with the door up. Remember this is still a 13R system with areas outside of the unit meeting some of 13, but not all.

Heads) Are you flowing 0.10 Gpm/Sf (Openings to outside of building /unit are not limited by 50 Sf unless it's to another protected area, such as a corridor or protected exterior walkway.) Say yes to the above and design 4 heads 0.10 Gpm/Sf. (You may still ignore the garage door per 6.8.3.2) Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.

The front wall is completely open and each garage serves 2 units. 6.8.2.2 states that each compartment can nothave openings greater than 50 sq.ft. I am interpreting this to mean openings into adjacent compartments not to the atmosphere and therefore a 4 head calc would be appropriate using dry heads flowing in accordance with NFPA 13R. Thoughts please...
