pulse signal was used for fallout, but it was never used for nuclear powerplant meltdowns.... Exelon corperation, for example, the company that designed, built and operated Peach bottom NPP, Calvert Cliffs NPP, Three Mile Island NPP used for the former 2 exclusively thunderbolt 1000s. Three mile island used a majority of ACA sirens. None of which were capable of pulse. The NRC never put a requirement for a mass notification reverse 911 system that required the ability to sound a pulse signal.
The pulsed signal is meant to be used for fire departments. It is a variation of Hi-Lo, the Fire signal. For war-type threats, the appropriately named Attack signal is used which is a wail. Nuclear fallout is within the scope of a war-type threat.
There was a huge fire in a town downwind of me and the amount of smoke is incredible. What’s scary is that the sirens in my areas were playing this exact tone
You could have totally passed this off as a synth of Newberry's old system, as it consisted entirely of thunderbolt 1003's and one 3T22 that all ran the fire signal with each of the thunderbolt sounding similar pitches to those in this video.
Somebody with an untrained ear that's never heard a siren may find this relaxing, but one who knows the meaning of this signal would be stoned. The person that is ignorant to siren signals may sit there and listen to the sirens, relaxed, while radiation slowly eats away at their body. And when they finally realize, it would be too late. The creepy implications of this signal is what makes it so scary.
Pulse is a variation of Hi-Lo. Both are meant for the same purposes, just one may be better than the other depending on the geographical area. For example, if a 3T22 is in a wooded area you may consider using pulse because both tones at once in short blasts will be louder and penetrate trees better than alternatively playing just one tone at one time, which is Hi-Lo.
No, it is not. Almost all civil defense sirens installed were not coded sirens, and for the sirens that were, coded signals were never used for war-type threats. Pulse is a variation of the Fire signal, aka Hi-Lo. The Fire signals pulse, undulating pulse, Hi-Lo, and undulating Hi-Lo are supposed to be used by fire departments to summon volunteers. The signal for nuclear fallout would be the Attack signal, as nuclear fallout is under the scope of a war-type threat, which the Attack signal is used supposed to be for. The whole premise of damper equipped sirens is for them and their coded signals to be used by fire departments.

! ObamaTookMyCat ! The cyclones can do pulse

This signal could also be used for volcanic fallout as well. Could have used it in 1980 for areas east of Mt St Helens
@@chrisziegler4085so can 3t22s and superbanshees and some rare banshees can do pulse
@@chrisziegler4085 only when they are equipped with a damper and the majority of cyclone are not. that includes the three mile island cyclones.

I just love this art
Kinda gives me that "storm in the night" feel.
The art helps me get that feeling. It also says "The NWS has issued a Tornado Warning" on the bottom right.

Gives me that goosebump feeling
Gives me the Power outage feeling
“Do not look at the sun”
Wow!! That was pretty damn sweet! Never heard that pulse signal before
That's probably a good thing.

@@sweebow5288what is up with your profile pic 😂
WHATTTT
I love the ambiance 💖 Thank you so much 🙏
ahhh, you tied in the 1003 pulse with the 3t22 pulse!

It's very terrifying.
This sounds like a vibe
Sounds like some sort of piano or keyboard in the background that sounds like a song beat
perfect for samples in a song

This Was In The Background Of
The Phoenix, Arizona Evacuation Alert In Ultimate Serial Killer Remastered
I Just Comment About That Lol
Hey..uh.. do you take requests?
I'm sorry to say I don't as of right now.
Ah, shoot. Okay.
The picture looks cool and scary lol
I can hear the 3t22
hey nice drawing bro
This sound could be used for a Civil Danger Warning or a wildfire.
Idk why sirens aren't sounded during CDWs or CEMs.
The wildfire or just fire is hi-lo tone
The pulse is for nukes...
No, it is used by fire departments to summon volunteers, that is why it called Fire signal.
@@Joethaboss66 That's high-low

@@Joethaboss66 no it is not you idiot, it is used to signal the public “A nuclear radiation hazard is imminent, Take shelter now!”
Dumbass.
Read the thunderbolt manuals from the 60's and then you will understand.
This siren is heard in SPCHermitage 1258’s _Monsters of the USA_
In?
How long is each pulse?
Around 1 second on / 1 second off
.75sec on .75 off
I've never heard that kind of pusle before...can you tell me where can i find these Tbolts playing these?
Its a good thing you haven't. If you actually heard this signal you be running.
@@cometchris1090 why are they used for tornado warnings?
@@Anzac1 pulse is only used for Fire calls iirc
@@iacentralfishing5610 correct. but in some places it could probably mean like chemical spills, i believe.
Scary
so scary ±
Nice Siren

@@Can-Kashi OH NO
@@Joethaboss66 I saw somewhere it was used for nuclear power plants to warn of a melt down.

So eerie. Imagine hearing this going off in either a war zone or a severe thunderstorm, it sends shivers down my spine just thinking about it.
