A RU-vid first. Sounding off two 120VAC Simplex 2903s with AC 2901 horns at once. Simplex 2903-9050 light with 2901-9549 120 volt horn and 2903-9152 strobe with 2901-9525 120 volt horn
there’s actually a video of a dorm room with that 9838 style ac horn with the more common visual plate with it being a 4903 idk why they’d ever be with 2903s the simplex logo gets cut off but they were made around the same time for a little bit emerald square mall has real 9838s or maybe even 9846s on 2903 strobe plates
