The Siren Board

Something tells me that it is a Denver siren rather than a Sterling. I have never seen any Sterling with divided rotors. Only Federal, "Denver," and Erick had rotors like that, and Erick never made horizontal sirens as far as I know. I believe that these have either 20 or 22 ports on a low-RPM motor, so it should sound about the same pitch as a huge Model 2.

what's this siren? it's atop the fire dept. in Galesville WI

That is a Federal Signal STH-10
Here's a pic from The Civil Defense Museum website.

Are you referring to the STH-10 in the background or the cute little audible warning device in the back seat?

lol!

Thanks for the awesome up-close pic of the Federal Signal STH-10.

I assumed the siren atop the fire station would be involved with fire station-type duties, but now I'm wondering if the siren would also be used for severe weather? any ideas/guesses?

Tornados, sever storms, hurricanes, fires. It basicaly depends on your location.

The Ida siren is a Whelen 2000R. These sirens were never that popular around here, but Ida bought it to replace their SD-10. Sadly, I liked their SD-10 much better than their Whelen.

The siren at Exeter Twp. is an old WS Darley product. I believe it's an a Federal Model 5, but in a unique housing. Moreover, the flood lights under the siren are indeed used for deicing purposes.

That's a horrible pic. You can't even tell if it's a siren or not.

It is most definitely a siren. It is behind the Sinking Valley VFD outside Altoona, PA. I don't have a digital camera other than my cell phone, so that was about the best I could do. I will borrow a camera one of these days and get better pictures.

I have never heard it, but according to friends that live near it, it's single tone. It looks like a stack of plates, covered in rust. In my 10+ years as a siren enthusiast, I have never seen another siren of this type, in pictures or in person.

Drove up to Hamilton today to get a closer look at a siren I that I couldn't get a clear view of from Live Maps (Google doesn't have a street view of this area). This is what I found...

Looks like a half version of the HOR, very neat! I see news things every now and then on here, makes me wonder exactly how much we don't know.
