Jim,

I don't believe NFPA 72 prevents the automatic resetting of room smoke
detectors.  Indeed, based on the Hotel occupancy NFPA 101
(2003)specifically states that sleeping room smoke detectors are NOT
to activate the general building alarm (see 28.3.4.2).

Most hotel occupancies that I have been involved with do something
similar to what he is trying to accomplish.
