My installer just installed this exit sign. http://www.homedepot.com/prel80/HDUS...ceffdfgidgml.0 Here's my problem: I had him hook an on/off wall switch to it. I don't want the exit sign to be on when no one is in the theater if possible. The reason I ask is because when turning the on/off switch off, a fuse turns off in the fuse box. My installer has tried two different fuses, a 15 amp and 20 amp. Is this exit sign meant to not have an on/off wall switch connected to it? Any help is appreciated.
