2010 Air Raid Siren Demo

First video of the new series! :) Chris and Paul explore our giant air-raid/tornado siren.

[@billmoran3812]

As a child in the 60’s I remember the civil defense siren at the end of the street. It took a good five minutes to wind down after it was tested.

"The Little Red Forklift That Died." That's a great title for an illustrated children's book

This ACA PN-20/RM-130 is believed to be from Eden Prarie MN, a Federal Signal 2001-SRNB now stands in its place.

[@MoldySiren]

yup

[@TheCasualSirenEnthusiast]

Oh, well that explains the red.

[@Siren1000T1]

That kind of siren isn't even 30 years old yet. It can't be any older then 1989. Appearntly these sirens quit in 1998 when ASC changed into the Tempest line.

[@Midwest_Sirens]

That siren is a ASC RM-130 or a PN-20 and that logo is the ASC/ACA logo and it was made in Milwaukee WI around the1990s

[@minnesconsinsirens6803]

I think it’s a pn20 because you can see the ACA sticker just slightly.

[@GunBroker100]

Being a child of the cold war, these sirens are real familiar to me. They represented the spectre of nuclear war to us and were no laughing matter. Running at full power and speed it would produce sound levels that would certainly deafen you if you stood that close to it in operation. I lived a city block from one many years ago and when it was tested all other sound vanished in the wail of the siren. The one you have appears to be one of the sirens made by Allied Switch and Signal or Bendix Corp, between 1955 and 1965, given the fiberglass horn and motor cover. Those made earlier were all steel or steel and aluminum. Incidently the part located inside the horm is the "Sound Projector" assembly.

[@aether9747]

LuxDude2003 Vacuums it possibly is an aca pn20

[@hardrays]

thanks for the anecdote!

[@buzzbang7930]

When using the 20 amp DC power supply, perhaps a proper start/run capacitor hooked up to it will get it moving. After all, that what their used for. You should let the older guy explain everything with out you taking over the show. I would think that it already has a start/run cap in circuit, but I don't know that because you never let the older guy explain everything about it. If you're a so called "Geek", then you should have explained the whole running circuit, including the caps if used with or with out, and why with or with out. Some DC motors need start and or run caps, some don't. Explain everything the hows and whys, including the Voltage, micro farad values, how and why, faze delay, power factor correction and perhaps the duty cycle on run caps and a little explanation on RMS and Peak to Peak voltage. Something for the kids and green horns to learn about too. And let the older guy talk and demonstrate things too.

[@eschersky]

loll, Really guys, the tension between you two is way too obvious! Take it easyyyy

[@Mr3z00z2010]

I hated the that skinny dude. He doesn't allow his colleague to talk or do anything.. Man u should be a professional and take communication skills course before u do anything.

[@Luda_chris]

I know right! He was being a complete dickhead. I feel bad for the old guy, probably has to deal with his shit 24/7.

[@rot_studios]

Yeah, the old guy was actually trying to explain and discover how the thing worked in detail and the skinny guy just hooks the thing up and fires it. Not only was that a big safety risk it was also very dickish

[@20kilovolt]

That skinny dude is Chris Boden he is a badger he thinks he knows everything much better and he's wants to make that clear in a nasty way. Without him I had already been subscribed to this channel. He also will endure no competition on youtube. so he has once said nasty things about PhotonicInduction.

[@pjousma]

yech, 2010 youtube shows, I'm gonna watch Photonicinduction.

[@danilorosich]

Yes, when the man started to explain what he was reading on the nameplate ( 15:28 ), he just goes ahead and plugs in the siren. Out of respect, you should not do that. I hate to criticize, but I don't care how little information that other man knew on sirens, he should have heard him out, not turn on the siren whilst he is talking.

[@BrendanW0214]

This is an ACA P-20. Our town used to have one, but it was replaced by a Whelen Vortex R4 because the chopper broke in it.

[@UpcomingJedi]

Paul is just in his own little world isn't he? I am surprised he didn't catch his fingers.

[@Alwaysdoinit112]

I got my fingers bit by a model 5 once. Not fun.

[@donnah6547]

My grandson is OBSESSED with Tornado SIRENS!! Not the tornadoes as he is only 5 but loves the sirens (I know, lucky me,) and we watch any kind of video the has a tornado siren in it! He wants to be a Storm Chaser when he grows up so who knows ,maybe he will? Anyways thanks again for sharing your videos :)

You have an ACA PN-20, from the mid-late 1980's.

[@ThunderTrain2930]

@@MaxtheSirenHunter It's a PN-20.

[@halpmeamcringe1538]

They are the same so it’s either a ASC RM-130 or a ACA PN-20

[@Screwdriversteve1]

How to loose a hand 101! This is a great video to demonstrate the need for lock out protection!

[@mozzmann]

Hey guys the Air is drawn into the centrifugal fan in the centre via the outside ring and the exhaust and siren sound is concentrated by the conical flutes into the pie grid in the centre. There will be some sound emanating back out the Air due to the pressure pulses created internally but not much. anyone that argue's against that has no idea of siren and speaker theory. . So to recap Air is drawn in via the outer ring and sound projected out through the triangular pie grid in the centre.

[@KSE828]

Out of all the siren vids i've seen on youtube, you guys are the only ones that actually seem to know what you're talking about! Love the vid!

[@oxtoolco]

Nice video guys. Thanks for sharing it. All the best, Tom

[@HomeDistiller]

dont you guys have a good size welder? i've started a car on a large homemade welder supply (when i say large it was 1/3 the size of the supply you had but i think it would be heaver)

[@davecc0000]

Horn mounted. Power on. It's what we were expecting.

[@ronniepaulinc]

the air intake creates the deep hollow sound and the exhaust creates that high pitch scream...

[@americansmark]

Glad to see someone with a passion for these. Subbed

[@hardrays]

why is the 20 amp power supply so big? thermal management uber alles or mecury rectifier?

[@dogeisgr8222]

if you would have to choose a siren witch one would it be ACA allertor 125 or Whelen wps 4008

[@StormTrackTN]

This is too cool. I have a few warning sirens myself and they are a lot of fun to mess around with. Just recently I did a complete overhaul of a Thunderbolt siren - you guys should definitely see about acquiring one! Ask Jeff at WSS, I talked to him recently and he still has a ton of Thunderbolts sitting around. You guys would have a lot of fun with it, especially since they run on AC power. Great video, keep up the good work!

[@TempoDrift1480]

Man I haven't seen that Morrison Forklift logo in years. I used to do side work for them in Michigan a while ago.

[@hugeshows]

Oh man, I just cannot watch you put your hands into that impeller while the battery is still connected. That is BAD BAD BAD. Don't do that!! What if that button box fell over and that momentary switch closed for just a split second? A DC motor will take your hand off in that tiny period of time.

[@eschersky]

[@jericotyler]

have you ever considered running it inline with an Ammeter to find the average amps?

[@BigDish101]

I prefer the dual note ones.

[@Bandit-Darville]

At least twice as good.

[@Exarian]

what are the specs on that battery? how much can it hold? how much does it cost?

[@themaintenancedude]

Anyone know where I can get a Carter? Or cad/cnc plans for the rotor and stator assemblies? I know it's a long shot :)

[@TheIrafeedie]

You know it is very difficult to understand people when others talk over them. When Paul mentioned what he is looking for "The chrysler victory....", Chris proceeded to speak over him and we can't understand what you are looking for. This happens many times on talk shows especially on KZbin, and its very annoying.

[@tomclark6271]

Bug Grinder... Sirens of this type commonly operate with a 240v-440v 3 phase ac motor which allows for slow starting torque and high speed eventually, much more reliable than DC. And, Chris needs a corrective interview with the safety supervisor.

[@Tigers9596]

how loud is that (in decibels) ?

[@sergeantbananiel3438]

Yeah but have you tried a Noctua A12x25?

[@ChaoticGoodChris]

@JustInn014 We painted it back in 2004. It was originally grey.

[@waynestewart1919]

You could probably make one with a table-top router motor. 😁🤪 I'd love a Federal Thunderbolt 1000!

[@21zachrwd]

this is a very awesome video i always wondered what was inside of these types of sirens, ive seen others before, very awesome

[@HSETM]

Do do they work for ASC?

[@ChaoticGoodChris]

@danz409 We've already left Kalamazoo. The taxes were simply unbearable. We're working on locating and securing a new facility somewhere in the SW Michigan area.

[@KWCDesigns]

Just to let you guys know, this siren is an ACA (Allerting Communications of America) PN-20 (Pentrator 20 horse power).

[@doverpoint1]

The siren is made by ACA, or Allerting Communications of America.

[@SWMOWoodsman]

Lily Dane Yep, an ACA PN-20 at that

[@doverpoint1]

Yep.

[@NeffSang]

Lily Dane it was later by asc and it was called the RM-130

Oh OK, I knew there were still some in place that hadn't been removed but I always wondered if there were still any that were operational.

The rotation sign just means which way it turns when the motor is fired up, but without the chain you can rotate it anyway.

How many Volts did you need for it to start? If it would start at below 1kV you could make it with an Microwave Transformer! (Because you said your 20A Power Supply couldnt handle it ;-) )

[@AximVidya]

They're putting 24V volts into it and it looks to be starting just fine, soo... something between 0 and 24 I'm guessing

that siren is sick!

[@STSGuitar16]

yall should really get two ratchets next time, ya know what im sayin? You guys have a very tense relationship and I love seeing you actually, honestly butting heads and genuinely not liking each other very much lol. The vibe really reminds me of Jamie and Adam on mythbusters. It is entertaining in the sense that you guys very clearly have a tumultuous relationship at best, but it also does really borderline being too real and tense in a way as well lol makes for an interesting convo for sure

[@theq4602]

I could never work on sirens I'm too tempted to touch the rotor whilst its spinning.

[@brian2k1]

Would be really cool to have a way to engage/disengage the spinning so you can get the doppler effect.

[@mozzmann]

Oh the current is so high because there are 4 windings as field coils and then 16 or so connected to the commutator and the brushes. Depending on the 24 V DC starter motor used you could be possibly pulling 80 to 120 Amps or more.

[@MARKSLIMM]

Nice RM 130! You need to get a Thunderbolt 1003 By Federal Signal !!! DO NOT EVER wind it up with your hand you can chop your hand off, Not Safe! Those other rings are for the heating pads to melt snow. Nice Video. I'm a Air raid siren Geek!!!

[@000StrangeFreak000]

Could you please measure the dB of this beast?

[@fredrickhamilton4945]

Nice upload. I was cringing at the thought of the power switching on at around the 8 minute mark when he shoves his whole hand in the rotor. Even the other dude was cringing.

[@RipleySawzen]

The power of these comes not in how many dB, but in how far those dB reach out. A firecracker going off may be 140 dB, but at 10 feet away it's just a loud pop because it's only a small amount of air. So this may not be as loud as you might think, even though it sounds loud from far away.

[@redfive2008]

The horns aren't shaped very well on this particular siren. All the sides are basically flat at the business end, which reduces the overall power of the noise. Horns with the flared ends will transfer more power into the open air, and will be audible much farther away. The Chrysler Victory siren horns are flared, which helps propel the siren's sound up to 25 miles away. Another guy built himself an oversized air horn with a proper flare, and it was clearly audible 2.5 miles away, and would probably have stretched to 4 or 5 miles pretty easily.
