It doesn’t have a sticker inside, so I’m not really sure what its model number was intended to be. I call it the Simplex 4251-20BL, but that’s not official.
Does anyone know what that would have been used for since the manual stations usually have to be red or a contrasting color ?
Maybe if the building has red walls? I suppose this was before code required a white square to be painted around the pull.
Ok makes sense
