2001's and a couple of really high pitched 1000's

Those really high pitched rotating sirens in the distance have to be Thunderbolt 1000's. If they're not, then I don't know what they are.

One of those does sound like the high-pitched 1000 in Downtown Topeka.

I hear a siren in Whoop at the start as well. Or a single-tone EOWS that got activated twice, because they seem to sound like Whelens for the most of their wind-up.
