I have a question that relates to installing security/voice/data/video in the area above a class 1 area. I my case its a major repair garage. Art 511 indicates that all wiring must be in conduit or use MC,MI,TC,AC cable above the 18" class 1 area. If the code permits Tray cable why not other low volt cables? I am contesting the fact that I need to have all of my security wiring in conduit above the 18" class 1 area(major truck garage).
