Muncie, IN has a good amount of their sirens near schools.

I thought I might as well make a topic to share some unusual siren systems in cities, universities, power plants, etc. Webster City, IA definitely has a strange system, with all of their sirens on the edge of town: https://www.google.com/maps/d/u/0/viewer?mid=1tfDIf7L29-K-rK4aItFG5T-1jyKPI3iD&ll...

Definitely a siren. I'm assuming the Hoermann either replaced or got replaced by it.

That Banshee is almost for sure coded!

The story gets a bit more interesting regarding the Mach. 1… Based off this advertisement from 1929, there was yet another Model No. 1. This was a “general alarm siren” that shared the same 10 1/2” rotor as the Mach. 3 (pictured right alongside). It is unknown if these were truly 1 horsepower, but ...

Like many other Fedelcode sirens at the time, there were several different designs just for the Model 1. So far, we know it came with up to five different housing designs, those being: A 2-louvre design : https://youtu.be/FB6kyvF9a2E A 3-louvre design : https://youtu.be/-VmsILGLFeI A 4-louvre design...

That looks like a Federal Model B

This Thunderbolt had its chopper and motor horizontally replaced by a Type B motor and chopper, the blower is nonexistent, and the rotator housing is missing. https://www.google.com/maps/@33.7131471,-87.3886783,3a,15y,268.64h,103.41t/data=!3m7!1e1!3m5!1scD-bbGR1aBWv2zWGlWS09w!2e0!6shttps:%2F%2Fstree...
