In a previous life I had a bit of experience with temperature sensors which weren't listed for "fire", but rather "overheat conditions". From what I recall (from some "fire" guys I knew), sprinkler heads, once activated, are destroyed and cannot be used again. That was a long time ago, though and technology may have improved since then. Also, testing with water *should* not lead to a problem if the heads/pipes are dried properly.

The location does seem odd, and you are correct about the spray pattern being the determining factor. I think this is one of those that would be outside the scope of a typical home inspection, due to the complexities of testing/verifiying various fire extinguishing sytems.
