Hello! I volunteer at a small museum and in our storage we found a Morse code fire alarm. I would like to get it up and running so guests can see how it works. Now I’m no electrician so I don’t know if it takes dc or ac and if I could damage the mechanics inside if I pick the wrong wires at the bottom. The center silver wheels teeth are the firebox code and its hits on the brass to its right to tap the message. the black handle winds it up and white lever is it’s on button basically. From what I’ve seen online it’s was probably connected to the grid and another wire went straight to the firehouse. Any advice or help would be appreciated! I also have a video of it working so feel free to message me for that or other questions! Thanks!
