wow that require large power supplies for single phase siren, 30 Amp is not a small power to use capacitor banks to reduce load, thanks for the information that a good siren once, I would like have one.
An air raid is an arial bombardment by aeroplanes, typically of the type experienced by many cities in the last war, London, Warsaw, Rotterdam, etc....air raid sirens warned the population to take cover.
Air raid sirens are not used just in war time. In the 1980s in Northern California, I remember the air raid sirens were sounded prior to the spraying of the pesticide Malathion every few days in an effort to wipe out a Mediterranean Fruit Fly infestation. It gave you warning to get indoors lest you get caught in the poisonous spray.
@brianchris4 Well yeah, Of course. The Sirens share the Same Port ratio, 10/12. They sound different when driven by the motor, because they spin at different speeds, and most likely alternate at 50hz instead of 60hz like the US does. The 2T22 has more of a "comforting" tone to it, But nothing beats the eerie wail of a Carter/Gent's/Castle Castings siren like this. I'd sure like to hear one in Operation!
Hi Dan, if you look on ebay and type in 'air raid siren' in the search, there is one for sale now.....it ends soon so I would hurry up! They do come up for sale on ebay fairly regularly.
hi there is a castle castings air raid siren, (same as mine) on ebay at the moment. It has been deactivated but it is not difficult to reverse this. You might get it cheap. Log onto ebay and put in air raid siren in the buy section.
Hahahahahaha you know it, but a normal drill wont spinn fast enough. Try powering it up, at worst, you'll trip a breaker. But please.. let me know how it goes.
Actually my drill would....the siren spins at 2400 rpm at full throttle, my drill spins at 3000 rpm at max rev. Admittedly it would take longer than the siren motor to get there, but it would. The other consideration is my ear drums! Standing next to an air raid siren at full revs is not advisable!
I would need a 30 amp cable wired to the mains system to test it....not really practicable for one brief test. lol
Hahaha, yeah. I've got 30 amp all over the house though (had it installed for a DC originally, and just kept it in the basement). Test that motor, but regardless, its still an AWESOME thing to own!
Yes, i wouldn't sell them. I've got two, a 3 phase and a single phase one. I've tried the 3 phase when it was on the farm I bought it from and it works perfectly....The neighbouring farmhouse (3 miles away ) heard it!! lol
I've got an idea: Wear earmuffs over foam earplugs. That should protect your ears at least to the point where you're not deaf. LoL. That's what i'm going to do if I get a Model 2 siren.
Shit. I shoot my AK47 with just ear plugs, and I'm totally fine. As long as you don't plan on sticking your head in the horn of a Thunderbolt, you will be fine with either one.
I suppose I should try and test the motor. I've a feeling it is not going to work. The siren has never been used, when I undid the wiring box the rubber blank that fills the hole where the cable enters was still intact and the terminals were all pristine. A friend of mine also has one of these single phase sirens and his was the same. When it was tested the motor was dead.
The motors are inside the casing of the siren. The reason I've had to use a drill is that one is 3 phase and I don't have a 3 phase power supply, and the single phase siren still requires a 30 amp supply which I haven't got laid on to the garage. Also I'm not sure if the capacitors that came with the siren still work. It needs testing. I hope to power it up one day! Watch out for the vid on youtube when i do!
It still has the motor inside the casing, but I haven't got the power supply for it (needs a 3 phase supply for one of the sirens and 30 amp for the single phase)
There are some of these sirens still in use as flood warning sirens in Norfolk, Essex and on the East coast, but generally they were all scrapped in the mid nineties when John Majors' government dismantled the siren network in the uk, ostensibly on financial grounds. You can see, and hear, one of the Essex sirens in Dan Wisbeys excellent film on here.
There is one on the naval base at Portsmouth that is still in use. There's a video of it on here. It is rare in that when they test it, which they do regularly, they sound the 'Alert' not the 'All Clear'
There was a town not far from me ( Goodhope, Ohio ) that had a siren like this but it was painted bright red but then when I came to get a picture they must of scrapped it. :(
Hi Andy, Simply put, the two rotors (the red parts on each end) draw air into the casing of the siren (with the slots). This air can then only escape when a gap between blades and a slot correspond. the faster the rotors go the higher the pitch. There are 12 blades on one rotor and 10 on the other. This makes the siren sound a perfect minor third. This gives these sirens their ominous sound. Hope this helps.
I bought the single phase one from Ebay, it cost £450 and the 3 phase one I got through a contact and it cost £750. There have been quite a few on ebay recently fetching £250 to £850
Actually this drill goes at 3000 rpm, and would take the siren up to it's max revs of 2800 rpm, but I'm a bit worried about the neighbours (and my ear drums) so I haven't let it off full blast yet!
Hi, these sirens were built by the Castle Castings company. They are of the same design to the Carter Sirens that were used in the second world war in Britain. The two impellers have 12 and 10 blades respectively which produces a minor third and gives them the ominous sound. My date from the seventies or ealy eighties.
Hi, thanks for the posting. These sirens are slightly later than the forties ones but are the same design and same sound. They continued to be maintained until the siren system was scrapped by the Major government in the mid nineties.
if they are permanent rated capacitors at the mains voltage you can put them across the mains direct and take a current reading.that will give you the impedance in ohms ,then using formula for impedance of a capacitor (which is 1 over 2pye f c)where f=mains frequency,c is capacity in farads. then using ohms law you can see if the ohms calculated and the voltage applied gives same current calculation as you get from you ammeter reading ,if they match the capacitor is working to full spec.
err...thank you for that...unfortunately physics was always my worst subject and you lost me after the first sentence! lol I really need to get the electrician in and do it for me. Thanks for the info though.
Would love to! unfortunately it's not as easy as you would think. For a start I'd need to get a 30 amp cable wired up from my fuse box, and secondly the two capacitors that came with the siren have yet to be tested to see if they will hold the current. I'm hoping to get it wired up soon and then I'll post a new vid of it operating with the motor....hopefully!
go to the local hardware store and electric dryer wire it is usually rated for 30 amps at 230v be sure to add a breaker/fuse first though to avoid overload
if the motor load is over 10 amps run it from the main breaker box. if if under 10 amps you can get Romex which is the wire houses are wired up with and run that from you 13amp socket. good luck. message me of you need any more help:)
