Скачать или смотреть Dover Impulse Elevator Directional Lantern/Chime Overview/Test

Here's a video specifically focusing on the Dover lantern. For those of you who ever wanted to see the back of one of these things and see how they work, here you go. In reality, all this lantern is made up is four incandescent light bulbs (believe I have seen up to eight on other lanterns) and a chime box consisting of a circuit board and speaker. The rest is just a plastic shell with a few screws. Actually surprisingly cheap. Nice thing is that unlike brand new elevator parts, most of which are solid state, these old Dover parts are completely conventional. All you need is a power source and you're ready to go.

This video just shows what the back side looks like, how it works, and testing it off of 24 volts DC.

CVE9120 got several of these lanterns from the famous modernized DOVIS elevator, but he hasn't ever made a video of them, at least not yet.
