This is a fire alarm pull station made from the mid-late 1970s to the late 1980s. It came in variants, including a 'break-glass' model, where a metal 'hammer' was meant to be struck upon a sheet of glass before access to the lever could be achieved. The model number for the break-glass version was 4251-30. #425120 #425130 #alarm #fire #pull #simplex #station #system
