Heh, this company (small outfit named after the owner) did alarm AND vacuum too! At any rate, they do seem to be with it and know what I’m looking for, are making logical choices, and ask questions of me (not builder!) where appropriate. About the only glitch I had is I was getting 4 ceiling speaker lines run with 14/4 to each speaker, and for some reason they put the second set of speakers in series from the first. Was caught in time.
