Had an interesting visit with the Port Authority inspectors yesterday. I was there for fire alarm, but they provisionally gigged the new LED 2 x 2's for not having two wires independently supporting the fixtures from the building structure. Since my office had spec'd the fixtures, after I got back I went on a tour through the IBC at section 808 and kind of hit a dead end since we don't have a copy of ANSI C635/636. What it appears to me is that it's about the weight of the fixture, the seismic zone, and whether the ceiling grid is light, medium, or heavy-duty. The fixtures are 20 lbs a piece, but I don't have any of the other information (that's the architect's baliwick). What has been your experience regarding independent support for fixtures?
