I'm doing a dark room which has a foyer associated with it. The door to the dark room is a conventional door and I believe there is supposed to be some kind of interlocking between the two doors in the foyer (one into the foyer from the hallway, the other into the actual dark room) and the lighting in the foyer.
i.e. such that the door to the dark room itself cannot be opened until the outer door is closed and the light in the foyer is off.
Does anyone out there have any experience with this. Looking for details showing how this is best accomplished, manufacturer's who provide such systems, etc.
Thanks,
Mike
