Had not thought of that, most sprinkler systems I see are wet systems.
Nonetheless, though, as Nick said "heads could be damaged by freezing temperatures" - I was thinking about a wet system having water in the head and freezing, however, the head itself could have water remaining in it from being tested (all sprinkler systems are supposed to be tested with water, not just air), and that could cause problems with the heads because of freezing, or, maybe even the heads themselves could be damaged from freezing temperatures - I'm just not sure.
As far as its location goes, it would depend on the the sprinkler head spray pattern, not sure if they make one for mounting that close to a side wall, but they might.
