Honeywell Q43-3A3CK1 Vibratory Horn

Here’s a video of my Honeywell Q43-3A3CK1 Vibratory horn. I think this thing is actually a re-branded Benjamin horn of some sort. However, what makes it interesting is the fact that this horn actually operates on standard 24VDC. Most other horns of this style and era operate on AC current of various voltages instead.

I’ve had this for several years, but finally got around to adjusting the mechanism so that it produces a more consistent tone. It still has some “hiccups” in the video, but overall its performance is greatly improved. Enjoy!

To be honest, it sounds like one of my old vacuum cleaners.
