Oh how I miss these going off on a Monday morning. Part of my childhood until I was 14. First lived behind Broadmoor then on to Yateley. I remember dad rushing to work whenever they went off at any other time
@@gsmooth4279 they only went off on Monday morning for a test. As far as I remember if someone escaped the siren would have sounded until they were caught, and then there was a different tone sounded when they were found
Use to live in Lightwater and you'd set your watch on Monday at 10am as the sirens kicked in - Remember our school going into lock down when the sirens went off at anytime other than 10am on Mondays 😊
+Amelia Violet I have to be prepared with tripods and a plan of what I'm going to film. Normally involves my main camera zoomed into the siren and recording on a second camera to give additional views - makes the edited version more interesting to watch. They are "fairly" loud, I don't mean that you have to cover your ears though. Thanks for your comment :) Matt
to be honest, i'm quite surprised that the CS8s served for 6 decades! sad we don't have many CS8s left in the country, that being; carstairs, Plymouth and supposedly Newport. personally, theses are my favorite siren. good video, every now and then i tend to watch your broadmoor and carstairs videos to keep my mind of things! 👍
Sound real loud like a war alerts isn't! That's very interesting video, my dad been in German the end war. But is not being with him family anymore. Now we're good friend with respect of better than family of government war... Is a long story anyway! My dad knows about it. Now I live in Woodford (North East London). but my other family in local country the UK. Anyway, excellent video. ^_^
These sirens were never used in the war actually. They were brand new in 1952. The difference between these sirens and WWII sirens is the dampers on the ends that produce the Hi-Lo sound. Because of the cold war, there was always the possibility that Air Raid Sirens could need use in the future. Broadmoor couldn't have sirens that made the same sound as air raid sirens, becuase that would cause mass confusion - people wouldn't know if the sirens were for a broadmoor escape or an air raid. They had to use dampers in order to ensure that their sirens made a different noise/tone to an air raid siren.
any idea when the are decommissioning them all? I know a few of them are still working at the moment. Have any been removed already that you are aware of?
If u want a better view of the sandhurst School just go to the basket ball court next to where you were and there is a hole in the fence, crawl through and there you go get as close as you want, the chavs in our local area have cut a hole in the fence so you can actually climb to the alarm...
What a sound, awesome! Imagine one of those on a fire engine, you certainly wouldn't miss it heading towards you that's for sure! I lived near rainhill hospital near Liverpool and they tested theirs on a Sunday but they didn't sound anywhere as good as that one
Hi, good question, but no. Their only purpose is (or 'was' because they were removed about 3 years ago now) for the purpose of warning local residents of an escape. We don't really have servere weather in the UK (or it's not that common) so we have no weather warning system here.
+broken solar panel I'm not 100% what is doing the timing here. On a different video I had one camera on a tripod filming the camera whilst I was with the other camera at the bottom of the siren tower at the control boxes. I was expecting to hear a relay or contactor switching on and off operating each shutter probably wired to a flasher circuit. Once the main contactor fired the control box was silent.
Due to the laws of physics, the lower pitch sound travels better over distance than the high-pitch tone. The high-tone shutter is deliberately left open for longer then the low-tone shutter to compensate for this.
Now first off imagine seeing more of these with horns. I’ll be here in America. We had the 3T22 originally used during the Cold War and World War II, but nowadays is served as an active tornado siren found in big town, small town and local communities
Ainsley Harriot They warn of an escaped patient from Broadmoor High Security Psychiatric Hospital. They are tested every Monday at 10am. Unfortunately, the sirens will be decommissioned later this year.
Now I know about this sirens...this is a psychic hospital like a jail (sorry I am german) and YOU ARE standing at wikipedia about this sirens good!!! ;)
They should have done this... Go to America find however many Thunderbolts they need, restore them, take those sirens back to Britain, and replace the old Broadmoor sirens with the T-bolts
In these old UK Civil Defense Information Bulletins, they were talking about Gray Warnings (fallout arriving in an hour) and I think they used CS 8s like this one to make a pulse tone.
+Benjamin Fuller Not heard of the pulsed tone before but I suppose it's possible by closing both shutters at the same time then opening again repeatedly.
The whole point of Broadmoor using the CS8 was make sure that their sirens sounded different from Air Raid sirens. Civil Defense used multiple different ways to warn for fallout including bangs, whistles and dongs, according to the Protect and survive films made in 1978. I don't recall seeing anything alluding to Klaxon CS8's.
That's because they dropped the Gray Warning between the Civil Defense Information Bulletins and Protect & Survive. A pulsed tone was meant to warn of fallout arriving in about an hour as a Gray Warning while Black Warnings, fallout imminent, was given by gongs, whistles and maroon rockets.
Bon Ron Well, then if I lived there and heard these sirens go off at any time other than 10:00 am on a Monday, I would make sure all my doors and windows were locked. There are some in San Francisco, California USA that are leftover air-raid sirens from WWII. They are now also tested every Monday at 10:00 am and would sound in the case of a tsunami, earthquake, or any other reason that an emergency alert would be sounded on the local radio system (ie. a kidnapped kid).
what siren out of A & B & the reast will be removed first ? if its siren B im gonna go for it although it may piss dogs off but it find the siren B the wiled one i used to own a siren befor but it was a fagatized midget & it was a us hornet i later got rid of it
+Amelia Violet Hi Amelia, the sirens will be around for a while longer yet. It was decided not to remove any sirens until the new hospital is complete (years away)
There are only 13 satellite sirens and they are about 20 miles away from where I live, so not too difficult to visit them. Luckily I had a long term project in the area of the sirens a few years ago, so was not difficult to visit the ones I filmed on a Monday at 10am.
I think by the term wailing, are you referring to the "ramping up and down" of the rotor speed? I think this is what you mean, adjusting the motor speed to create this effect. As they are now, no. The motor in the middle is switched on, it goes up to full speed and the two tones are created by the shutters over the air-intakes on each rotor. One rotor does high, the other does low. But it would be theorestically possible, but you'd need some kind of motor speed controller to do it (VFD variable frequency drive).
mrmattandmrchay mrmattandmrchay You wouldn't need a VFD... without the shutters closing on the wind down (motor shut off) the rotors still have a lot of momentum and would keep rolling for about a minute or two. But with the shutters there is no air resistance or barely any so the momentum lasts about 5 mins. The red alert signal (wailing) is possible on these sirens but you'd need to either manually switch the motor on and off or get another controller as the one that comes with it is not compatible.
***** Are they definitely "taking it down"?. I've been in contact with a Security manager at Broadmoor and apparently they are now retaining all existing sirens until such time as the new facility is ready in 2019, where there will be only one - on the facility itself.Not sure about all the current maintenance issues.Bon Ron, please let me know if there is evidence of an upgrade or take out in progress?
my new video shows one shutter stuck open, the other is stuck closed - sounds really weird - I'm uploading it in a day or so (carstairs junction siren)
***** These are all in towns surrounding Broadmoor hospital (google it) - this place is not a prison, but it contains the most dangerous people in the country that, due to their condition, cannot be put into a prison. It's essentially a high security hospital with some dangerous people inside. During the 1960s someone escaped and killed some people in the nearby town. The public were really concerned, so these sirens were installed to warn people if someone escapes. The most recent escape was in 2001 I think. Security is very tight now with massive improvements (inner and outer boundary fences, etc) so really the sirens are not really needed anymore. There is a new hospital being built which is due to open in 2019, so these sirens will be decommissioned. Nevertheless, currently they are tested 10am on Mondays.
+mrmattandmrchay if they dont need them then why do they test them ? i love the siren B & if there selling the Beast im gonna be the 1st out my area to get it & i donnno wat id do wit hit it probly have it on my house roof & use it as a weather warning sien
+mrmattandmrchay youtuber Oliviah Mcollng lives near there she lives near siren B reson is coz we both no each outher after meeting unexspectedly in london
Roman TBoman If you are asking "if it's possible" then some, yes, indeed you can although you'd have to get into the siren enclosure first. One at the Traffic Depot one in Bagshot doesn't have an official 'enclosure'. Most of the tower hatches are open at the top of the ladder as well.However, due to the nature of these sirens (being connected to Broadmoor) I'm sure that the police would be very interested to arrest anyone that did climb the tower for "tampering with a secure hospital security siren!". It would probably be treated seriously. Members of the public would probably report it as well if they saw anyone up there.If you are asking "me" to climb the tower, then I won't be doing that as I'd lost my job if I picked up a criminal record for doing so :) I do some dodgy stuff, but I wouldn't climb up to one of these in clear view of everyone.
+AwesomeDesertTortoises yep... known him for nearly 12 years haha! By the way I remember you from ages ago and you have one of the strangest profile names (but I'm not saying that in a bad way :) its just interestingly strange if you know what I mean)
It is absolutely criminal that they have decomissioned these. I honestly don't believe (having seen the siren K autopsy video) that these cost much to maintain. A simple electromagnet, a motor and some switch gear. Understandably the motors might burnout over time, but I bet most are original. Now it will be social media or text message to tell you someone is on the run! I think they might live to regret removing these.
EVERY MONDAY? What kind of secure hospital is it? Biological weapon research? lol Edit: Oh... high security psychiatric. What are they expecting the patients to be capable of? Edit2: I read the notable patient list. Damn.
Yep, tested every Monday since they were installed in the 1960s. The technology back then was cutting edge, but suppose they have to regularly test them to ensure everything will work if there was a real incident. I suppose now, they could be adapted to work over the GSM network of course, but back then it was a copper cable from siren to hospital control room :)
