I really enjoyed hearing your story of how you started researching into sirens. Our stories are quite similar actuallly. When I was 8 years old I used to regularily visit a park in North Vancouver BC Canada with my mom and grandparents on visits. I would regularily stroll passed a decomissioned cold war era siren. I asked a lot of the same questions you did as well. My biggest question was "how could something that was so important for the publics safety 50 years ago be left to rust and decay like this?" I'm 25 now and I have spent the majority of my life researching into Canadian cold war era Civil Defense sirens. Also to answer your question about the last siren in the video rotating from in the wind...Federal Sign and Signal 500SHTTs sometimes have issues for with the belts in their rotator mechanisms. Cheers from Canada. 🇨🇦

That particular rotating siren was known for having issues with the drive belt for the rotation mechanism which is why it moved in the wind. The belt likely deteriorated and crumbled apart allowing the siren to move freely. Kind of like putting a car into neutral.

You should totally be a voiceover or commentator.

the sirens phone and power lines are cut and the single directional sirens aka the "megaphone" sirens used rubber belts to rotate the sirens which now have disintegrated leaving those sirens able to be swiveled by wind or other causes. they would also rotate 360 degrees and not back in fourth in s small radius but all of the sirens are inactive and very rusted

Omg im glad im not the only one who noticed it moving I’ve seen 113 move before when i was younger i thought it was just my imagination 6:12

You made it sound creepy

if you heard a sound that was really loud and it wasnt the wind or cars it mightve been testing

Rather odd that they kept them up despite not using them in decades. They could use them for earthquake alerts or tsunami warnings.

A large majority of these sirens would still work, however many have not been tested in 30+ years. There is actually a very large group dedicated to sirens all across the country. It has been a life long hobby for many of us.

6:16 it could be the wind. They usually have belts on the rotator so it can’t spin freely. But since the siren was abandoned the belt could of rotted and plus, it was a windy night.

at 6:40 you ask if the siren was being tested that night? Was it just the wind? From your video I can comfortably say that the siren was being tested by ONLY the wind. That model siren rotates to broadcast its warning tones, its not geared to do a side to side motion like someone shaking their head to signal "no". Below the siren assembly itself, one can see the glass insulators for the power feed. There are no power cables connected to the siren's power feed, which I guess at one time came from the utility pole in the same photo. That power feed is completely barren, so the siren has no electrical power and electricity alone operates it. What you saw, in my opinion, was a result of the force of the ambient wind's positive pressure against the surface area of the siren's head, resulting in visible motion. The same physical principles can be observed with wind driving a three blade turbine to generate electricity. My wordy explanation can be replaced simply with "that's a disconnected siren being blown around in the wind".

6:30 “side to side” they actually go in a full circle

The big megaphone / F.S. 500. Does rotate 360°. Now since they have been through weather and age and now move in the wind.

i remember a couple of years ago my mom and i took a trip to downtown los angeles and on our way there we passed by two SD-10’s on accident, i still remember where they stood, one was directly on a sidewalk, and the other was in a public square, both of them are still standing.

Siren hunting really is a very rewarding activity. I've spent a few weekend days driving through small towns in MN to find unknown sirens not marked on the MN Siren locations map, and it's always just a fun rush to find another one, hiding right there in plain sight.

I'm from Fresno, CA. Even in Fresno they have some of these 50+ year old sirens still standing. It's true. I never noticed them until a couple years ago and wondered why they were there. All over California they were installed. A lot are still standing and I hope they stay standing to be honest.

I have one right outside my building

I don't think wind pushed it I seen many rotating sirens on windy days and the wind didn't move them

I am the biggest fan of tornado sirens, Also one really old tornado siren been tested! I don’t know the name of the video, but I love tornados and tornado sirens

Music is creepy

Sirens that were abandoned model 5t 500AT SD10 Scrivo

these sirens should be noticed

I been there before and I was amazed by how many sirens there woer I loved it

I love sirens

I wish those sirens where in new Zealand

It’s very neat and amazing to still see these sirens here! My question is do they still work.

Here's the siren types LA had: The tiny birdhouse sirens are the Fedelcode Mach 3Ls. The birdhouse sirens with a small vent in the middle are Fedelcode Mach 7Ls, and Mach 7s. The birdhouse sirens with the wide vents in the middle are Federal Sign & Signal Model 5ATs. The wire spool sirens are Federal Sign & Signal Model SD-10s. The rotating sirens are Federal Sign & Signal Model 500A-SHTTs.

Just imagine trying to find these sirens in GTA V because GTA V is based off of LA

I've always loved History and I've been obsessed with air raid sirens since I was 12 and I've also seen some move and I'm not sure if it was doing it on it's own or what

number 4 is an hor sirodrone

the first siren we see is an SHTT 500 federal signal

Cold War era air-raid warning-siren is adjacent to a store with a sign that reads "Russian Gifts."

how did I get here

That’s a Federal 130-508

they should re test them again

Will these be still in use?? I would like a test from those babies!

Wow you have a fs 550 in you city 😉👍

very good video! the editing was very good!

yes it was the wind. no it was not being tested. you would have heard it. more than likely that infrastucture that used to operate it is long gone.

I was in elementary school when I first heard one and wondered, " when they came from?"

Too bad you weren't able to display a Chrysler V8 victory siren. Ain't none of em standing in their original locations.

Content great, have subscribed - please improve sound slightly to make it more awesome. :)

As a kid years ago i use to hear em the last Sunday of the month

I love how informative this was!

CNN “ The Japanese attack was mostly peaceful.”

Wow, what an awesome video! How do you only have 94 subscribers? Well, now you have 95!

I remember the ones in my old naborhood from when I was a kid''''''''' turning the big 52'''''''' ohhhh nooooo I'm getting old!!!!!!!!!

IT wasnt the wind, it was the ghosts of the past silently calling out. Whispering the dark fate that they once stood vigil against.....

Where I grew we had a siren that was used as a call for the volunteer fire deptment. www.twincities.com/wp-content/uploads/2018/04/thinkstockphotos-147014239-e1523551513800.jpg?w=1024&h=576

The first one is a Federal Signal 500. Most of these are SD-10's.
