Vintage Wheelock signal bell system for fire alarms, school, and notifications by western electric.
The bell is rather large along with being pretty heavy and is mounted on a piece of wood. I plugged the bell in and it did ring I cant seem to figure out what triggers the alarm for the system. Item is in nice looking condition and seems to be working.
