I was trying to remove the trip when I guess I accidentally pulled the whole housing out of the ceiling. I can remove the release clamps onthe side (not sure if this is the right term) and pull the entire unit out (ie. not fixed to the ceiling). The clamps look like springs. Basically, I think the releasing clamps should be holding the housing unit up but it won't. Any ideas of how to fix this?
