Iconic nuclear warning siren sound effect

[RamJett]

Hi all.

I'm sure that most if not all of you would know this iconic sound effect (https://www.youtube.com/watch?v=HHLERpO4HuI), but what I'm here to ask is if anyone has any sort of information surrounding it? Location, model, etc. I'm fairly certain that it's a 9 port HOR Super Sirex, and I'd put my money on it being located somewhere in Canada as near the end of the video you can hear a 10/12 port siren that sounds a lot like a CLM.

Does anyone have any definitive information about this recording?

I don’t have definitive info but I’d think it’s more 10 port sounding to me, and I can agree with the CLM on that one.

I believe that is an ASC T-128 and a 3T22. Located at Three Mile Island.

This recording predates the T-128 by many years, plus TMI never had any 3T22’s…

I think this was recorded in Canada. The siren is probably a Model 2 with some CLM sirens in the background

[clm 10 12]

Pretty sure the main siren is a 10 port Hor Siro Drone. Sounds very similar to the one in this video. https://www.youtube.com/watch?v=Ef8u6t6meBg I've also heard people say it could be a 10 port Carter vertical siren on 60 hz, but those were rare even in the UK, and I'm not sure there's much evidence that any were shipped to North America. It can't be a model 2, the windup is linear, so the siren heard has an induction motor. I'm not sure what the siren in the background at the end is, but I don't think it's a CLM, doesn't sound directional enough. This recording dates back to at least the mid 80s, but probably even earlier.

There was a fire siren that was a 3T22 that I think went off for emergencies as a backup for the P-15 next to it.

That could be it because in the vid the 10/12 is quieter than the 10 port so there’s a chance that the p15 had something wrong so they used the 3t22

A year ago i've found a documentary from 1963 that has the same recording in it, along with a STL-10 interestingly enough. timestamp is 1:01

So this recording/stock sound effect does definitely date back even earlier.

Yeah, it might not be a T-128 if it was recorded in the 80's. It might be an unknown 10-port siren or a Thunderbolt 1000 at Chopper Level 2 or 3.
