Federal STH-10 at Purdue

This pole-mounted Federal Signal STH-10 siren is located in Purdue University's Hilltop Apartments. I took this video from about 100 feet away, against a building, so the sound is great -- even with the wind-down at the end. You can hear it get way down. It's got that classic "air raid siren" sound, though it almost sounds like its rotor might have a balance issue, or the bearings might be worn. Other sirens audible in this clip: Federal Signal Thunderbolt 1000T (on highest chopper Xformer tap), Federal Signal 2001AC-127, and Federal Signal 2T22 (all the other campus sirens are these).

that siren is very underpowered... we have one here in my town and its alot faster and louder. When it goes off you can see it twist the wood grains on the pole its mounted to. all I can say is they dont make em like they used to!!

@purpledragonslayer It is a single phase STH

I think the note that this STH-10 sounds is more ominous than the tone that an STH-10 is supposed to sound.

[BrandonDevers]

Wow. I used to live ¼ mile from a Sentry 10V siren. When a tornado warning was issued once, that siren sounded in attack mode and jumped to the same pitch as this siren.

[whoisthisguy724]

At this pitch it would technically be considered a STM-10, single-tone medium pitch 10hP, like STH-10 is single tone high pitch 10hp, and STL-10 is single tone low pitch 10 hp

[POTATOESLOL]

@rbuszka I thought Texas was the most active.

[Bonemeal2]

Yeah, I could immediately identify the wavering of the Thunderbolt. Sounds like the one in Aitkin, MN.
