I think if I was to deal with this guy you mention, I might tell him that I'm authorized to install burglar alarm systems, I'm licensed to do so and How do you know these low voltage guys aren't scheming. I think it's discrimination not to sell a product to someone, specially with a lame excuse like that. They can't write their own laws at the supply house. I remenber back in the early 80s when i first got my license the supply house asked if I was licensed. I said kind of bluntly, what state would you like to see and handed him 3 licenses. I didn't think supply houses of any type would still be conducting themselves like that. It's not like your buying a gun,
