There's a video from somewhere in town during a tornado warning where you can hear it

I think that this could save everyone from a tornado right away

Same

There's 7 of them that I know of. This is the only one still in use.

@@TylerShawWx is the one in Nevada at the FD working? Fire siren I assume?

@@tornadoandfiresirensofohio8479 there's more than one. One is supposedly active but is falling apart.

@@TylerShawWx o ok

@@TylerShawWx Where is the 2nd active one? Just curious

I was around the corner next to the church so I wasn't shooting against the sun. I wanted to go up the alley some but there was a guy filling the propane tanks in the alley and his truck was making all kinds of noise. I'm pretty sure I drove past you on my way out. I have a red WRX.

@@TylerShawWx Yeah the alleyway would have been a good shot too. But glad you were down here. Wish I could have met you.

And super banshee and 8/12 port Allertor

And Soundmaster

Good ole 8/12 ports

#soundmaster115

I remember hearing it from my house about 20 miles away. Pretty distinguishable for sure

@@thatgaycat 20 miles? Dang!

One of my friends out there heard it from Palomino Dr, which is about 6 miles west of Calhan. That sound most definitely carries well over the open terrain there.

😅😅😊😊sirine 🎉🎉🎉 baherwithery jiuywe 😎

Yeah they are super rare this is 1 of 7 or 6 left in the world currently this is the only known one that is still in operation. And yes it is still here in 2023 as I went to go record a short video of it.

Still activated by a switch inside town hall.

​@@TylerShawWx ah the antenna threw me off, must be for something else then.

@@UmbreWolf The small antenna is for Calhan Police Dept. They're on the 800MHz trunked system for interoperability. The large antenna is Calhan Volunteer FD. Several VFDs around there operate on the 150-170MhZ (2m band) VHF.

@@djscrizzle Alright, fair enough.

550AT is incorrect. Not sure how people came up with that.

No shit Sherlock 😂😂

Nope there are 2 active ones in NY

@@BRISTOLFORCE2009 if you are talking about Yonkers, NY then you are wrong. Those are literally inactive and rusted! 😂😂😂 If they were active they would’ve been recorded as literally every siren in NY has been recorded multiple times. Here is a tour of them ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XPEuSeyha0U.html

@@BRISTOLFORCE2009 And there is 3 500DHTTS AT RENO sparks NV

The SD-10 only looks and sounds a little different than this siren.

Oh yeah, I noticed

So this model of 500 is in LA?

​@@SylvesterTheSupernaturalThose are 500 SH (Single Horn) Not DH (Dual Horn) In case I'm wrong, I'll correct it

Now I can't unsee that

Just make sure to check with the city for the actual test time. They seem to change it year to year. It used to be more consistent.

Aight

@@TylerShawWx also is this siren still here in 2022?

@@TheEST270SPO when did I record it?

@@TylerShawWx am the same person on a different account I finally saw this thing while i was heading to Kansas of course it was when it didn’t test. But yes I saw it! I posted a short on it.

This thing existed long before the P-50 was was thought of. Also. Calm. Down. Please.

Its a horizontal Soundmaster

all three of you are wrong, it's basically an 8 and a 12 port Model 7 sharing the same motor and strapped to a rotator.

It is more of a rotating soundmaster than a 2T22

I feel like federal signal should have used this port ratio on thunderbolt’s, 2T22’s, and model 7’s

@@BRISTOLFORCE2009 So 5/6 and 6? I mean 4/5 port I would say carries further than 5/6 or 5 port because of it’s undertone. It also carries the furthest with a 5M blower

That's like $40 in gas though

@@TylerShawWx I’ll have to record it sometime then since I live in Norfolk

both of them sound ditherent

this siren is very old that it can be as old as 200,000,000 years old

and this are my favorite sirens❤❤❤❤❤❤❤❤

this siren turned on 3 times already

Omg I know right

Because it's 8/12 port

Colorado has a dry climate, it was maintenanced in the 1990s, and it's activated a couple times a year.

No

Same port ratio

Whoo

Not

you mean A C A P - 5 0
