I am reviewing plans for a college dormitory, three stories with truss framed attic. Spec 13 sprinkler system to be installed with attic sprinkling. The sprinkler area increase has been used and sprinkling would be required for the occupancy in any case. They are claiming V-A construction, I have doubts as the sprinkler can not substitute for the required one hour construction of the roof supporting structure and I do not find the provisions regarding truss protection in IBC 2009 704.5 very clear as to this situation.
