Emergency Siren Tones Signal Different Threats 

Imagine hearing all the sirens at once.

it's kinda scary that people went on snap chat to complain instead of getting inside...

idk why people think when the tornado sirens stop that the threat is over. People storms do not go away in 3 minutes

They have to replace nuke siren with "TACTICAL NUKE INCOMING"

should be a person screaming NUKE!!!!! TORNADO!!!!!!! FLOOD!!!!!!!!!!!!!!

Most horrifying in my opinion is the air raid siren. I hope to god I never hear that go off.

The sirens are controled by a soundboard lol

hmm Tornado Warning or Chemicals in the air..

Good progression of disasters here: Tornado Flash Flood *THERMONUCLEAR ARMAGEDDON*

No one: hmm i think the tornado sirens are going off Me: SiReN hEaD

Laughing here in Germany. We have siren checks every month

At the beginning, it is two whelen vortexs and one at 560 Hz sounding in sequence. Which makes it sound like a WWII Carter Air raid siren.

A threat is usually just telling you GET INSIDE! depending on the type of siren they sound different. Between a Whelen 4008 and a thunderb bolt 1000. The tones depend on the command box, the type of siren, and what the city wants

2016: scary mysterious siren 2020: hehe funni sirenhead

Some familiar Warning Sirens name: 0:50 = Whelen Vortex (4004) 0:54 = Federal Signal Thunderbolt (1000T)

wOaH tHeRe BusTeR My first reaction would be, “SIREN HEAD”

1:25 That is the one that goes off constantly where I live. There are the scheduled ones that go off every Monday through Saturday at 7:;00 AM, 8:00AM, 12:00 PM, 1:00 PM, and 5:00 PM. Plus whenever the volunteer fire department needs an ambulance or a firetruck it goes off. Plus it is also used as our tornado warning siren which nobody ever notices because that rotating horn is going off constantly in our town.

damn that one loud car alarm

Thank you so much!! I just had a siren go off and I wasn’t so sure if it was over when it stopped or not!

1:37 Is is that fucking internet explorer.

the first saturday of every month, 12;00 for 1 minute, is my tornado siren heaven

thank you fro this video this helped me alot.

Where I live, we have a siren that goes off at 10pm to signal curfew and the town tests their tornado sirens every Saturday at noon, as long as the weather is good so nobody panics thinking an actual tornado is coming.

The company I worked for had the same alarm for fires and tornados. We had a tornado warning and a lot of people went outside!

Thank you for making us overly safe. Xoxo we appreciate all news reporters.

Honestly, I'd be too busy laughing at the nuclear threat siren to actually find shelter :^)

the ones in the beginning sounded like Carter sirens

Ugh, the siren sounds give me goose bumps.

BHAHA the flooding alarm is my school fire alarm 😂

personaly i love those sounds

1:15 The 2nd siren is tested on a Bi-Weekly basis in the part of the U.S. that I live in. Then again I do live with in walking distance of the Northern End of the Delaware River.

I swear I heard a carter siren

idk about other places but here in Nebraska and Kansas the sirens will go off once a tornado warning is issued and again if an actual tornado touches down or is very likely to touch down

This is really giving me chills..

Interesting use for the high-low tone. Around here I think the only one used is just the regular siren, and many sirens lack the capability to do the high-low tone since it wasn't used much. Most sirens can only do alert and attack modes. AFAIK, the original meaning of the high-low tone has been lost to history. I've also been witness to a test in attack mode, which is concerning when you actually know what attack mode is and means.

The fast wail is what my county uses for tornado warnings

Love the showing of the Thunderbolts 😍

The flood one sounds like the intruder alert alarm sound from my old school

A CTI owned Thunderbolt never seen that before

0:01 this is not Carter. This is sound of two sirens. These sirens are Whelen Vortex and 2810.

1:14 1st tone sounds like the beginning of the Soviet anthem

1:26 sounds like a wolf

Well, I do hope that I never hear the fast wail signal.

i hear this everyday even right now

We literally get like no tools or education to even tell us what each mean. The government should implement this in our schools. I'm in college now but it'd have been nice to have been familiarized with the sirens back in highschool.

In my area alert is for thunderstorms and tests, wail is for tornadoes, fast wail is for any nuclear attack/ air raid, and pulse is for chemicals, and hi - lo is for flood and fire.

Is that a underpowered 2/3t22 at 0:00 or a carter/cs8?

if I hear this I am out off town fuck that.

Wow I never knew those sounds

who remembers the good ol days when a false alarms freaked out a whole state? good thing im a florida man

where i live there's lots of floods and our mayor hasn't installed any siren to warn us (we get notified by amber alerts) also a story: back in early 2017 there were rumors a tornado hit south of my town. i thought it was fake but on a night ( i had to sleep in my parents' room since my dad's cousin lives with us) I heard an amber alert and it was actually a severe weather warning

it sounds like Bert from Elmo's World LOL

"They certainly get you're attention"

imagine hearing this at night while ur walking

Those flooding sirens just went off like all around BA and none of my family or friends had heard them before

We have them where I live

The sirens in this video are a thunderbolt 1000t which looks like a square trumpet. A Whelan 4004 or vortex r4. And a whelan 2810 aka the black speaker siren. Reminds me of a tower of hockey pucks

For some reason I feel like if the nuclear attack siren went off and I was there, I would have a heart attack before the bomb even hit us 😂

It's all fun and games till the siren plays in the woods.

It's aloud and scary sound . But when there there's no other way that are there for your protection.

I love your video.

Me: I didn’t even hit you that hard. My brother:

Do we get siren checks because my state hasn't had on for all 5 years iv been here and many more since my grandma been here for around 15-25

Hi-lo is not used for coming flooding, it can be used for tornado threats aswell Wail is also not fulled used for nucelar attacks.

So THAT'S why the test lasts three minutes.

WHEN THE SIRENS GO OFF ME BE LIKE FRICK FRICK FRICK HELP ME

hearing a siren up close is worse than sticking a needle up your ears

It’s almost 1am and our sirens just went off. It just beeped for like 30 seconds and stopped… I can’t figure out what that even means

Lol did you guys see the part when they showed a thunderbolt but played a whelen sound?

Hol up this is the news guy from my city news but he works for abc now lol

i wanna hear what the "broken" chicago tornado siren alert tones are all about

It's like what you're grandfather said if you here a siren go seek shelter

Went to basic training at Fort Leonard Wood, MO... I can never unhear the fucking doorbell siren they use for general alerts on that base. Somewhat better than the high-ass monotone G# wail they use for weather alerts that bores into your skull, but there's still something kinda profane about THE doorbell sound, the one that is also used in a lot of clock towers, being used as an alert tone for everything that's NOT a weather alert...

Ive lived in canada my entire life. Ive never ever heard one of these

And most ppl gone ignore it thinking its just a bunch of loud fire trucks driving nearby

Today I heard like.. Loud honks and they were like 10 seconds each accompanied by sirens an octave higher than nirmal..???

I love the whelen harmony here

We're do you go

When is the siren going to stop here in Seattle. I can't turn if off. It's coming from my phone. I live in Senior housing and it's bothering my neighbors and can't turn it off. HELP

0:01 My sirens in Ohio

I just heard this sound that’s why I looked this up

>_> In Australia brisbane they have Whellen signals that alert flood. >_> Why my life has to be in that place?

to clear things up single tone doesnt mean anything, some sirens are dual tone (Federal Signal Thunderbolt 1000T for example) and some are single tone (Whelen WPS 4004). but the actual difference is the signal. a steady sound dual tone or single is Alert which is basically saying there is a storm watch. the wailing signal is called attack. This means that there is a tornado or servere storm and you need to shelter NOW. there is also a Hi Lo signal were a dual tone siren is switching between the tones. im not completely sure what it means but probably a fire signal or other storm thing. alternate wail is the same as Hi Lo but with the attack signal. it basically switches between the hi tone and lo tone while also in a wailing signal. Pulse and pulse wail are pulse tones (single tone or dual depending on the siren) and pulse wail is just pulse + Attack. i dont know what they mean but its nearly universal. also there are different types of sirens but thats another topic. also some county emergency offices sometimes dont use the signals for their listed purpose. and sometimes only use one. it really depends on what state and county and what they wanna do and what they know about sirens and what not

I used to live in Hawaii and we had tsunami sirens

I’m starting a petition to change every siren to Sponge Monger from Spongebob Squarepants.

no siren in more unsettling than the classical nuclear bomb threat siren in my opinion

Their flood tone is my city's tornado tone

Attack tone : wailing Alert tone : long alert Hi lo tone : fire alert or other Pulse tone : flood Alternate wail tone : tornado or flood Fast wail tone : nuclear attacks ------------------------------------------------------------ Growls : just a quick test of the siren All these sound 3 mins growl wont sound 3 mins

Where I live, they play the sirens all the time, idk why though

These things go off near my house like 3 times a week but nothing happens. I live in Delaware😂

I am living in Moore, OK. I can say that sirens are LOUD.

At the thumbnail is my favourite siren (federal signal thunderbolt)

Imagine an earthquake happened then Godzilla appeared out of nowhere

The nuclear siren sound like one of my toy fire trucks

no one: the thumbnail: *T H U N D E R B O L T*

2020: SIREN HEAD?

Whenever you guys hear the last siren wish rip for your own self 😌

Dose anyone know if the ThunderBolt works?

Now people know why theres a setting called "Attack"

The flood one sounds like a european ambulance
