I sure wish that we had more sirens in Canada. We usually only use them as fire sirens in British Columbia.

The Thunderbolt 1000T on top of the tower either A.) is set on chopper level 7 B.) has an air leak C.) has a reverse-wired blower

they never answered how they work, haha.

I thought they were showing how the actual sirens work...

There are 2 different types of sirens 🚨 There are electric sirens And Non-electric Sirens. The Non-Electric Sirens are powered by a Fan. The fan spins so fast that it chops up the air which causes a high Pitched noise what we call a Siren noise. But There are some sirens that are electric ⚡️ The electric sirens are sirens that do not have a fan. They are programmed to make a high pitched siren noise. Solenoids :) Sometimes sirens can make a hi-lo noise or a pulse Noise. To change the tone of the siren, Solenoids block the air which blocks the noise. Hi-lo is when one solenoid blocks the air and then the next. Pulse is when 2 Solenoids go at the same time. 🌪🚨 We all know some ways the sirens work, But most sirens are turned on by you’re city, Some state test their sirens at different times. Most sirens are tested by the city 🌃 And those are a few things I know about Tornado sirens 🚨 #Sirens #Solenoids

I just wanna know if it's possible to blast Darude sandstorm through the sirens for everyone to hear

When I was in elementary school, they had a tornado siren situated right next to our school. Every Tuesday it would go off at 10 am. It was a little scary at first, but eventually you got used to it. There was another one situated on the other side of town right next to another elementary school, too.

I saw 2 2001’s, 3 thunderbolt 1000t’s a thunderbeam, a model 2, 5, or 7, an alerter, and a mystery siren.

I live in Lafayette and the tornado siren sounded at 3:07 AM

I remember seeing this siren at 4 years old

Preset tone patterns are usually put into the sirens during testing, usually in the mornings at 10am at most municipalities. Here are the sound-tone patterns for the test siren activity: The first test firing is the plateau-tone pattern, usually for several minutes. (That is the glissando up, then a steady tone, and then a glissando down to end the sound.) Then there is a break for about 1 or 2 minutes, and the test-firing happens again in test 2. The second test firing is the multiple-sine-wave-tone pattern (the several waves of glissandos up and down), also for several minutes. Tornado siren emplacements are either this option - fixed emplacements (where the sound structure on top does not move when the siren is fired), or rotating emplacements - where the top part of the siren, like a Leslie pre-amp fan on a Hammond Organ, rotates when the siren activates. The siren stops rotating when the sound stops. The tops of those sirens are usually in a hyperbolic shape for maximum output of the siren din for maximum reach so that scores of residents/people can hear the sirens and take action if needed.

This is just like the fire alarm at school going off, and then somebody in the school's main office getting on the PA system, saying that there's no fire.

1:35 ITS THE tornado's toilet

0:39 federal signal 2001-dc

One going off in richfield MN right now. Been going off for 30 mins haha

you press up to 2 buttons normally. unless you are using the siren's control box.

Funny hearing a story from WCCO about a false alarm, seeing one of the famous airchecks from the EBS false alarm was also from WCCO (AM).

Me hearing tornado siren:I think it’s siren head

when i was in first grade i got to set the sirens in hennepin county off, i think that was in 2009 or 2010

1:55 The siren that is rotating is a Federal Signal 2001 The second one on the water tower Is a Federal Sign And Signal Model 5

Thank you

In Nicaragua,they turn on a tornado siren at 12pm. It just says it is time for lunch 🍴

My city can't afford a tornado siren, so I put up my own.

it works by electricity or motors

Das ist doch schön 👍

in croatia we don’t have that type of dangerous weather there are some sirens. Disconnected for 30 years

I agree with him when I was a little kid I used to be scared

1:53 2 sirens next to each other? why do that?

I heard that tornado siren

I thought once the wind hit a ceramic speed the wind made it go off haha

The Thunderbolt 1000T is In Minneapolis

storm alert

Good question but very bad answer! So how do they work? That's not in this video where the answer can be found

there was a practice today that no one know about

hey guys thegeekgroup has the named how do sirens work

I don’t even have a tornado siren at or near my neighborhood

Someone might priest it at three am

So... do we get to know how it works

Pov: it's the first wednesday of the month and you're bored

At first I thought he said " I sure did freak " lol it's okay I know now he said Frank .

I remember this, me and my family hid in the basement.

There are different kinds of sirens the two kinds I know electrical and electro-mechanical. The electrical sirens use speaker drivers The electro-mechanical ones uses a stator, motor and a chopper so the chopper is connected to the stator a shaft is used to connect the motor to the chopper. The chopper and stator have rectangular ports that act as doors for air to go throungh thats how they make there always has to be a way for air to get to the chopper by a intake or a blower most electro-mechanical sirens have horns (not like air horns). There are also rotational sirens and omnidirenctional sirens, most rotational sirens have a rotator box and some don't. Omnidirectional sriens can send their sound in all directions without spinning.

A tornado siren is across the street from my new 🏠 house.

I have a tonado siten last night at 6:00 am and warning and it was an mistake

We need sirens for infectious disease warnings, and that should be actived using a switch that the public can use, for if they find themselves with an infectious disease spreading from person to person.

What's with these subtitles?

0:42 thunderbolt

I thought tornado sirens were automatic

“They want us to take them seriously” If I hear a tornadoe siren going the fuck off and it’s not Wednesday and it’s sunny and beautiful out, best believe I am NOT 🤣”taking cover” or “taking it seriously”

Better question: Who don’t you answer the question?

242 sirens in a county?

0:49 sick thunderbolt

The other science in reform where we live does it work anymore
