Federal Signal 500SHTT Tornado Siren in Alert 

I love how the Modulator just overpowers it whenever it points away lol. But man, that Modulator really completes this video. 2 of my favorite sirens going at once

Thank the VA Hospital for this gift of keeping this siren up. :D

Finally! I've been looking for this audio clip for AGES! I've FINALLY found the Rising Heat siren sound effect origin!

WE'RE MAKING IT OUT OF RISING HEAT WITH THIS ONE🗣

This is one of my favourite sirens

Finally i found the original rising heat siren!

FINALLY! I FOUND THE RISING HEAT SIREN!!!

YES, I FINALLY FOUND IT, I FINALLY FOUND THE ORIGIN OF THE RISING HEAT SIREN!!!

Wow all the sirens are synced together

This is it. The offical source of the Rising Heat Siren.

Sounds like a B&N Mobil Directo or a 10/12 port ACA Allertor.

OH MY GOD YES!!!

Sounds a lot like a Federal Signal 3T22 when it gets up to speed.

I hear the 500AT, the Modulator and the 2001.

Ah, back when it used to rotate.

The spinning 3T22

Still here huh, that is good. Long live the old Federal sirens!

CA has a lot of sirens... i am pretty sure there is an AT in that once city near sanfransisco with the power plants... (sorry i am from oregon but we recently took a vacay and i saw some sirens.

I love the tone of this siren, it sounds like a cross between a 3T22 and a Carter Gents Castle Casting.

Man I would kill to hear one of these. Nice vid!

@garyhstorms10 The STL-10 is long gone. Topeka's entire system has been upgraded and this is now the only working siren from the old system.

This is actually a Federal Signal 500SHTT

Will the STL-10 be fixed soon for the Statewide Tornado Drill i still remember that first video of this siren in alert along with that and the 2001 that sounded cool :)

On one of your vids of this siren I heard the stl 10 in the back ground. Now I hear a 2001. O:

That sounds creepy ... I'm from CA and I've never heard one in person :-:

it sounds like a thunderbolt and a 3t22 mixed

SOUND LIKE THUNDER 3T22 MIX

@garyhstorms10 eithera modulater or dsa

Thunderbolt and a 2t22

Anyone came here from Rising Heat? By ClayRanger and RadioactiveGirl?

Omg jayhawk I was there the other day! It's on the veteran hospital right?!

If its 10/12 its a 500SH-TT (Single Head Two Tone)

What is the siren that had no wind up ? being heard

It’s a 500-SH-TT.

classic

wat did the stl10 look like in topeka?

is that a modulator

This sound like ...

No I meant is that a modulator in the background and no I am not stupid.I am autistic

This is pretty much the only good thing the VA has ever done for anybody... their medical care is baaaaaaaaaaaaaaaaad.

4/5

r u stupid a modulator is not mechanical it doesnt rotate and it looks completely different
