Well, gang, BIGDOG03 get's the prise!

Going down the list, BD's intruction set was correct:

INTERCOM + #3 + EXT ...turned off the light.

I'm sure all your info was correct, it's just I was more interested in turning it off than how it happened in the first place ( and I'm a freelancer, not a full-time employee yet, so there was no chance to slaping anybody's hand).

Thanks again, y'all.
