Look at NFPA 13, 2007, 8.5.7, he may be looking at this as if it is a ceiling pocket. But in any case I couldn't find reference to a skylight smoke detector requirement unless it's being used for smoke control.
The following excerpt is from the IBC, 2006 limiting the allowable area but also giving the exception for a sprinkled building. But don't forget the above 13 reference with it's limitations. I'd ask for the specific code they are basing their directive on. [cid:184163119@22092008-3057] Craig L.

Down the hall where the bedrooms are is a large skylight. The dimensions are 16'x40'x3', which is 637 sq ft and a pitch of 12:4. The skylight and frame are all non-combustible. Right now the design has three extended coverage heads below the opening. They wanted us to put heads up at the apex of the window but through an exception now want us to put smoke detectors at the top and 10 (ten) heads around the sides. Does this sound unreasonable to anyone else?
