Allertor in Crescent City,CA

[fstbolt]

I Typed "Warning Siren" in Google and found this:


It Said in the Caption that this Allertor is from the 1960's
and the man being interviewed is Allen Winogradov. He is being interviewed by Richard Gonzalez.

That Allertor was installed a few years ago. There's a Youtube video where you can hear this siren: http://www.youtube.com/watch?v=381vqwFhXiE

It does not rotate and always points toward the low-lying part of town near the ocean. On the next building over is a hornless Thunderbolt 1000 that also points in this direction. The Allertor was installed to replace the Thunderbolt, but as of this summer, the T-bolt is still there. Also, there is an STH-10 at the harbor office that replaced an earlier H?rmann E-57. The E-57 is sitting on the ground behind a chain-link fence behind the building. This could be a rare chance to score an E-57 in the United States.

Go get it?
Save it!

Yeah, but I believe you need 220V or 440V three-phase to run an E-57.

... Yeah, but I believe you need 220V or 440V three-phase to run an E-57.

I would try to find a single-phase motor to power it.
Or connect a belt pulley wheel and power it with a bicycle.

And I'd paint it to look like a mushroom.

An E57 looks rather small to be powered by three-phase current.

An E57 looks rather small to be powered by three-phase current.

That, too.
Appears small, but I have no reference for comparison.

And three-phase is often a problem to obtain.
Seems like these would be.tter powered by single-phase.

What horsepower is needed?

The Thunderbolt looks like it has a Solenoid, or is that a little bit of the horn?

[Daniel]

An E-57 rotor is about the same size as a Model 5, so three phase is a possibility. Unfortunately, I'm not in a position to collect sirens anymore.

I think all German power is three phase for motors running on that voltage.
