Assuming a true NFPA 13R system then NO. This is per NFPA 13R (2002 edition) paragraph 6.8.5 which states:
6.8.5 Sprinklers shall not be required in attics, penthouse equipment rooms, elevator machine rooms, concealed spaces dedicated exclusively to and containing only dwelling unit ventilation equipment, crawl spaces, floor/ceiling spaces, elevator shafts, and other concealed spaces that are not used or intended for living purposes or storage and do not contain fuel-fired equipment.
Note that I believe this section was new for the 2002 code and I don't have a copy of the old edition handy. Might still be able to argue not putting them in there under the old code.
