It sounds like this siren actually has a problem. See CBS 58's story on it:

Hopefully Milwaukee County will get the system back up and running 100% soon.

I noticed in the ACA brochure that jkvernon posted ( http://www.airraidsirens.com/forums/viewtopic.php?t=7079 ), the Penetrator 10 is listed as having a 15 horsepower motor. Wouldn't that make it a P-15? :? I thought the motor horsepower rating was the only way to identify if a siren is a P-10 or P-...

Here is a link to another story about the county's upgrade (with a video).

I didn't know there was a siren at Summerfest. I think that's the only Federal Signal siren on the system. I tried looking for it on Google Maps, but it's like looking for a needle in a haystack. As far as other sirens in the county, here's what I found: Model - Quantity Alertronic (6000?) - 1 Aller...

From what I gather from this article, Milwaukee County E.G. will still be responsible for activating the sirens, but they might only activate sirens for the directly affected areas.

Excellent video!!! Interesting how the fiberglass ripples. I never noticed that before. I like the echo during the attack cycle, also.

Keep the great videos coming!

If I had the money, and time I would take a little road trip up there to see that baby in action. I imagine it sounds spooky with P-50s and 10s mixing with it, that is if there are others sirens near it. I don't get up that way too often but I know there's an Allertor about a mile east of there, a ...

What is the blower's psi (pounds per square inch) rating, as in how much air pressure does it produce and at what speed/velocity does it travel? 450 cubic feet per minute @ 10 psi. Can the Hurricane's rotator RPM level be changed like the Thunderbolt, or is it fixed at 2RPM? I don't know if it can ...
