Recently acquired an old Bell Systems outdoor/loud area ringer made by Wheelock. Number "KS-16301" stamped inside. Large cast iron or steel case, uses 110VAC for the ringer, signalled by 20Hz, 60Hz, or DC.
Anyone have any source for wiring diagrams/options?
N.B. Either this or something similar in external appearance was used for alert horns at SAC bases -- possible still in use at ACC bomber installations.
Thanks,
