First video in over a month due to my personal schedule. A test of my Faraday 5810 polarized 120 volt electromechanical horn (Simplex 4050) with an early gen non-recessed Simplex 4050-80 light plate with 120VAC socket (Aka: 5810-60)
COOL! I think thesdx had a Honeywell branded version of this horn. I don’t know if it was polarized, but it sounded at the same frequency as this horn.
