    Being a child of the cold war, these sirens are real familiar to me. They represented the spectre of nuclear war to us and were no laughing matter. Running at full power and speed it would produce sound levels that would certainly deafen you if you stood that close to it in operation. I lived a city block from one many years ago and when it was tested all other sound vanished in the wail of the siren. The one you have appears to be one of the sirens made by Allied Switch and Signal or Bendix Corp, between 1955 and 1965, given the fiberglass horn and motor cover. Those made earlier were all steel or steel and aluminum. Incidently the part located inside the horm is the "Sound Projector" assembly.

    When using the 20 amp DC power supply, perhaps a proper start/run capacitor hooked up to it will get it moving. After all, that what their used for. You should let the older guy explain everything with out you taking over the show. I would think that it already has a start/run cap in circuit, but I don't know that because you never let the older guy explain everything about it. If you're a so called "Geek", then you should have explained the whole running circuit, including the caps if used with or with out, and why with or with out.
    Some DC motors need start and or run caps, some don't. Explain everything the hows and whys, including the Voltage, micro farad values, how and why, faze delay, power factor correction and perhaps the duty cycle on run caps and a little explanation on RMS and Peak to Peak voltage. Something for the kids and green horns to learn about too. And let the older guy talk and demonstrate things too.

    Hey guys the Air is drawn into the centrifugal fan in the centre via the outside ring and the exhaust and siren sound is concentrated by the conical flutes into the pie grid in the centre. There will be some sound emanating back out the Air due to the pressure pulses created internally but not much. anyone that argue's against that has no idea of siren and speaker theory. . So to recap Air is drawn in via the outer ring and sound projected out through the triangular pie grid in the centre.

That said, even if you could get one in moderate body condition, a lot of them have had the engines removed. If would probably be easier to build your own from the manufacturing specs.

    The power of these comes not in how many dB, but in how far those dB reach out. A firecracker going off may be 140 dB, but at 10 feet away it's just a loud pop because it's only a small amount of air. So this may not be as loud as you might think, even though it sounds loud from far away.

    • @redfive2008
      @redfive2008 5 років тому

      The horns aren't shaped very well on this particular siren. All the sides are basically flat at the business end, which reduces the overall power of the noise. Horns with the flared ends will transfer more power into the open air, and will be audible much farther away. The Chrysler Victory siren horns are flared, which helps propel the siren's sound up to 25 miles away. Another guy built himself an oversized air horn with a proper flare, and it was clearly audible 2.5 miles away, and would probably have stretched to 4 or 5 miles pretty easily.

    But yeah, this one is still pretty big, and obviously plenty capable. But I'm baffled as to why a chopper only that size, whose motor doesn't look really much bigger than maybe a clothes washer motor (or the size of motor on a motorized excercise bike like an Exercycle brand) would need so many amps!
    Anyway, this was really cool, guys! I've always wanted to see the chopper in one of these!

    For some strange reason, UA-cam decided to pop this 10 year old video popped up on my feed. Talk about cringe worthy. Working on high current devices with power connected. Older guy with no hearing protection. Despite the cringes, it was interesting.

    Guys you do realize that the lower the voltage, the more amps the motor will require? That is why the breaker trips...

    this video is only 10 years old but it looks like it was filmed in the damn 90s

    I know this has been up for awhile, but .... You said "The chopper outputs through these channels....". When you got to the impeller, well, I would think that the air being 'pumped' out, comes IN through the the sides and the 'gap' discussed at 9 minuets into the video. IMHO :-D
