13R Garages are covered in 6.8.3 and 6.8.3.2 Says that garages accessible from more than 1 dwelling unit (you say 2) (Are they considered separate buildings per 6.8.3.1) if not, protect in accordance with 6.8.2 Are you less than 500Sf total area in garage Are you 130Sf or less per head coverage Are you using QR heads (6.8.2.3 does not list garages as appropriate for res. 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...
