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.
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.
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
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.
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.
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.
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.
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!
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.
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 :)
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.
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)
@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.
@leeofbacup he he he, yeah. We have a new production crew and they're all in training. Though if you want to donate your services to help us make a real intro we'd certainly appreciate the help! :)
There's a Chrysler siren on top of a building in Kansas City it's disconnected but I heard that the power is still connected it just won't sound off during a test of the city but the problem is that it's a three phase power
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.
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.
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.
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.
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.
This is a Nice Siren.....Never seen a RM-130 Before....but the Design looks like a Transition Between the Past Penetrator P-10/P-15 and the Modern T-128
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 RU-vid, and its very annoying.
There was a serene on the telephone pole right in front of my house growing up. It got tested every other weekend. That's what you get when you grow up in a military town during the cold war.
They use these types of sirens as tornado warning devices in Texas. I was in Amarillo once when one went off across the street. It was so loud I could hardly think straight....
Hilarious.... Paul has more stuff attached to his waist line then a construction worker and won't let Chris power the unit back up as he tries to read a date, and spits out the gear reduction. Great team work fellas.
@ilikepie123rs actually guys this is an ACA(alerting communicators of america)(right before they changed names to ASC[American signal Corp]) PN20 or RM-130.
Good luck with the Chrysler air raid siren. Only one, maybe two are still in running condition. The rest were literally left on their placements to rust away. That said, even if you could get one in moderate body condition, a lot of them have had the engines removed. If would probably be easier to build your own from the manufacturing specs.
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
Given the casual attitude toward safety displayed in this video, I would not at all be surprised if that skinny dude has killed or maimed someone else or himself by now.
