MORE INFO:
This was back in 2014 when the sirens existed - they are no more (more info below).
The sirens were tested at 10am each Monday and I have separate videos for most of them sounding.
Me and Chay went out to find them all. It was a very interesting bank holiday Monday!
It was a good day as we did other things like play football in the parks, McDonalds and see the sirens of course!
BY THE WAY - In the video, I have offset the two sirens by two minutes, but in reality all 13 sirens are tested together. This is for illustration purposes (see the times in the bottom left and right).
THE SIREN HUNT:
It was a mixed bag - some viewable from the street, some hidden so much that you'd never know they were there (unless it ativated!), some in council depots, compounds, parks and believe it or not - in the middle of housing estates metres from houses! (would scare the living daylights out of residents if they went off at 3am!). Some are in secure places with no access at all.
HOW THE SIRENS WORK:
The Klaxon CS8 siren.
A 415volt 3 phase motor spins two rotors on either side. One rotor is for the high tone and the other for the low tone (the one with most holes is the HIGH tone).
During the escape siren, the airflow is cut alternately to each rotor by a shutter on each end producing the distinctive high-low tones. I believe these are known as CODED SHUTTERS - hence the model name Klaxon "CS"8.
Both shutters are opened together for the all clear tone. You can just make out the high and low frequencies being produced together if you listen.
WHY ARE THERE ESCAPE SIRENS?
They were installed in the 1950s/60s with the intention of warning residents in surrounding towns and villages to remain in their homes and keep their children supervised following the escape of a Broadmoor patient.
In those days security at the facility was nothing like it is now and some would say they are no longer needed. But they do a job - "to warn". Escapes can never be "impossible", but "more and more unlikely" as security and procedures improve at the hospital.
2018 - WHAT NOW?
The siren system was originally installed in the 1950s. The copper telephone wire system is outdated and parts have not been available for many years now.
With various faults developing and lack of parts and knowledge to fix it, a decision had to be made to 1) Update the whole system (13 locations, the infrastructure, the actual sirens, everything!) , 2) Remove 50% of the sirens, update the ones that are closest to the hospital , 3) Maintain the sirens to the best of everyone's ability, then scrap the system once the new 'more secure' hospital has been completed.
They decided on OPTION 3,
Bearing in mind, in the 1950s we didn't have telephones or mobile phones and the secure hospital didn't have anything near the security it has now AND there is a new 'more secure' hospital nearing completion, it was decided to decommission the whole system rather than spend a lot of money to update it.
By the end of 2018, all sirens will be removed.
A new siren will be installed on the new hospital, which doesn't sound that interesting (electronic, not motorised). In fact, during testing it doesn't make any noise?!

I usually don’t think of sirens as scary. But I’ll make an exception for this one. That high-low droning gives me the chills! And the context of this particular siren is terrifying! A tornado is pretty scary, but a madman on the loose, in a neighborhood where you live, is really different. I would NOT want to live there.

[@mrmattandmrchay]

Yes, they were designed to 'warn' residents of an escape. But the only 'loud' sound they could come up with in the 50s/60s was this! Nowadays they'd be a speaker siren where they can put what ever sound they want. The old siren sound I agree would terrify me if it activated in the night.

[@kimifur]

I do live there, and I grew up where the sirens were tested regularly. Strangely I've always found it reassuring that should anything happen, we would all be alerted right away. It's much easier to protect yourself from a single insane criminal than it is from a tsunami or earthquake. Crowthorne is actually a really nice village to live in!

[@piggystriker2]

+MontisEinsatzfahrten Intern. emergency response (Emergency Response) They are there because the hospital is a very high security mental asylum, and they were there to warn the surrounding villages of air raids(by the nazis) at first, however now only used to let people know if a patient escapes, as a patient over 50 years ago did escape and killed a child. And there are over 16 primary schools in the sirens radius so it's better to be safe and sound.

[@TarHeelBrit]

I grew up next to one and they had no public alert system (Oakwood Hospital Maidstone) we didn't know someone had escaped until the area was flooded with police and hospital security. Side note. A friend of mine lived down the road in the first house. We were playing in his cellar when he showed me a bricked up tunnel. His mum said that it was a tunnel under the road into the hospital. I was used in Victorian times so well to do families didn't suffer the shame of taking their crazy relative in the front gates. Instead they went into the house and that was it for them. They were taken through the tunnel to the hospital.

[@mrmattandmrchay]

+Super Trini Gamer Cool, yeah that's right... WHY ARE THERE ESCAPE SIRENS? They were installed in the 1950s/60s with the intention of warning residents in surrounding towns and villages to remain in their homes and keep their children supervised following the escape of a Broadmoor patient. Patients at this hospital are generally dangerous people who need specialist treatment and would be a danger to the public if they were treated in a standard hospital. Some should be in jail but need treatment - their behavour would be a threat to other inmates. When the hospital was originally built, security at the facility was nothing like it is now and some would say the sirens are no longer needed. But they do a job - "to warn". Escapes can never be "impossible", but "more and more unlikely" as security and procedures improve at the hospital.

I'm not sure what it has to do with a secure mental hospital, but in medical terms a "Patient Zero" is the first patient identified with a specific illness or disease in a country (or the world). Like, for example, the very first person in the UK to come down with Ebola would be marked as Patient Zero.

The first time I heard this siren, me and my family were house hunting in Owlsmoor. (The estate closest to Broadmoor.) I was only 11 at the time. We had just walked out into the person's back garden, when the siren went off! I screamed, hyper ventilated, curled up in a ball and shook uncontrollably! I had never heard anything like it in my life before! I have never forgotten that day!

[@martinsmiffy6753]

As a school kid I remember very clearly hearing this every Monday at 1000hrs then silence then the all clear at 1005. It only sounded twice the entire time I lived in Bracknell to signify an escape. Once whilst at school when I was in final year and my mum had to collect me. Me 6’1 my mum 5’4 !! And then once in the middle of the night . We lived less than 10 mins from the hospital and my dad got up and checked all doors and windows .

[@Xaelloss]

Quite an educative video -- as usual. I have always been fascinated by pure mechanical sirens rather than electronic ones... Thank you for sharing this!

Sirens Of South Carolina main difference is that shutters open and close on a hinge, meaning the shutter stays where it is but turns to allow the air to flow in. Solenoids on the other hand move back and forth in front of a passage. They are connected to a spring and motor that slides the solenoids in front of the chopper back and forth. Also solenoids stay open when non active while shutters are closed.

just tell them its for exhibition in a museum of sirens

[@KiloByte69]

Anna Powell MMM Nice.

[@DonEzioCorleone]

I remember back when we had that bad lightning storm 2 years ago. A bolt of lightning struck near one of the sirens, setting it off and people were freaking out thinking the Yorkshire Ripper had escaped.

[@mrmattandmrchay]

+Ethan Talbot (YorkShireBoi) haha. In the 80s we used to have an air raid siren near us and that was the same. It was disused since the war but sometimes thunderstorms would set it off! Its been removed a long long time ago now though.

[@racer927]

I've seen a video of a siren being set off from lightning so I believe your story.

[@Vexnatos]

Imagine working at Broadmoor, and hearing the escape alert, and calling to check which patient escaped, only to be told there was no escape.

Nice work mrmattandmrchay. I have lived in the area for almost 6 months now, but due to work / being unlucky I have never heard these sirens despite living about 1 mile north west of the Ascot siren. I have a Monday off work in a couple of weeks time so I plan on heading out to see the siren even though your video reveals one of the shutters is jammed at this particular location. It is interesting we had a siren when I used to live in Plymouth, which was also tested every Monday morning, this time to warn of nuclear accident at the dockyard and we had leaflets periodically distributed to us about what to do when the siren goes off. Essentially lock yourself in your house tune your radio to the local radio station follow instructions, if told take your iodine tablets in the back of the kitchen cupboard and hope for the best. Interestingly no similar advice since I have moved in here, although I expect it to be largely the same apart from the Iodine tablets, and to call 999 if a shady character is shuffling around outside your window. I don't think the one near Bracknell station works any more since it was struck by lightening a few months ago, I wonder if it'll ever get fixed. Thanks for the videos, glad to see you had fun searching for these.

[@mrmattandmrchay]

Robert Putt Thanks, and thanks for your comment Robert. Yeah wonder if the Bracknell Station one will ever work again. It was struck by lightning? If so, it probably took out the obsolete transmission equipment on the end of the phone line.

[@NattyTheGreatest]

mrmattandmrchay as far as I know the Bracknell one was replaced and it works again 😄

[@aminyamumsminge]

Robert Putt lucky you,I would love to hear this siren

[@enderpea5251]

I love the trains that passed it while it was there and running.

[@wingaard]

I grew up in Eversley in the 1970s and can remember these very clearly. We lived about 3 miles away. Thanks for posting .

Sound like a slow motion of a thunderbolt 1003t tornado siren

[@ivybesmonte2577]

Albert J. There is no 1003t T-Bolt... only 1003 or 1003a or 1003b

[@sarahrichards9087]

Brings back memories. I grew up in yateley in the 80's, heard this every week

[@mjyanimations1062]

something fell out when it was starting

Birds.

[@johnshawradio]

My Mum lived in sandhurst and once heard this on the way back from school - it was not a test - luckily they found the escapee soon afterwards

[@uglyafowoo7733]

The wind reminds me of a motorcycle taking off

[@FM60260]

I think they should have made them so the valves are open when the solenoid current is off (like Federal Signals Thunderbolt 1003 and 3T22) so they have a more traditional run down and could be used on an original GEC Autowailer.

[@mrmattandmrchay]

For reliability (and so they don't jam in the shut position) yes, absolutely. But I suppose they designed these so that after power is disconnected then the sound is muted as much as possible. I know you can still hear the 'wind down' but it would be much louder and may confuse some people if the shutters defaulted to being open (is this a high or low sound?). Also, with the shutters open, it exposes the siren more to the weather and anything that chooses to crawl in there.

[@gothamnetworks]

Brain Damage by Pink Floyd: The lunatic is on the grass The lunatic is on the grass Remembering games and daisy chains and laughs Got to keep the loonies on the path The lunatic is in the hall The lunatics are in my hall The paper holds their folded faces to the floor And every day the paper boy brings more And if the dam breaks open many years too soon And if there is no room upon the hill And if your head explodes with dark forbodings too I'll see you on the dark side of the moon The lunatic is in my head The lunatic is in my head You raise the blade, you make the change You re-arrange me 'till I'm sane You lock the door And throw away the key There's someone in my head but it's not me. And if the cloud bursts, thunder in your ear You shout and no one seems to hear And if the band you're in starts playing different tunes I'll see you on the dark side of the moon "I can't think of anything to say except... I think it's marvellous! HaHaHa!"

[@larrensmirren6860]

Legends say that the siren is still running down

[@coydog7902]

The sirens are gone

[@joshmckinnley745]

Speed this video up by x3 and it sounds just like a Thunderbolt 1003 Siren like we have in America.

[@tyroniousyrownshoolacez2347]

When it's too loud on your cellphone speaker. Wow! Thanks for sharing. 👊

[@minislayer2010]

I find this hard to sleep to

[@morbius109]

If ever a Fallout game was made that was set in the UK, part of the game map should definitely include eastern Berkshire and the Crowthorne area, so that Broadmoor and those spooky sirens could be a part of the setting.

[@ginkumpow3726]

They're coming to take me away! Ha ha hee hee ho ho!

[@e.j.thomas9994]

In the 80's it used to be a 10 am to 10:05am = two tones one after the other, followed by 2 minutes silence, then at 10:07 am to 10:10 am it would be both tones together. Then it would fade away, and that would be it for another week!

[@themowhillsvolunteer]

Iincredible, Awesome and terrifying!

[@RODALCO2007]

What an amazing siren devices. Pity that all this great technology ends up on the scrapheap unfortunately. Great video.

[@CliffNark]

And replaced with a mobile phone warning 💀

Wait! Is this CS8? For me its not CS8. Then what? Yes. This is CS8.

[@KRhythm2013]

I've lived and worked within 10 miles of these sirens and heard them for many years

[@ivybesmonte2577]

Can't hear the sirens BC I live in USA. I wish I can hear them for real... :(

[@mrmattandmrchay]

I've had a lot of people in the USA contact me about coming over to the UK especially to film these sirens! Unfortunately, very recently a couple of people travelled (they live about 1-2 hours away) to film them but neither of them sounded. So unsure which work and which don't at the moment.

[@ivybesmonte2577]

mrmattandmrchay my son only speaks english that's all! He also wishes to go to UK when he's a Grown-up! ;D

[@ivybesmonte2577]

Also searched UK on Google Maps. :)

[@gumdrop465]

I luv siren sounds it makes me feel anything can happen, be prepared u never know comes next. Sometimes maybe it teleports you the old time. I luv it ❤️❤️❤️

[@mrmattandmrchay]

It's a weird feeling listening to these activate, when you're almost underneath them!

[@gumdrop465]

@@mrmattandmrchay I see, I hope i can get to feel it someday 🌚

Zombie Apocalypse starting siren 😂

[@phillmiller587]

since these sirens are beginning to be removed you should try to get one of the decommissioned ones

[@solarsatan9000]

if anyone gets them where I can still hear them i swear I will hurt them becouse I have had enough of them

[@malkycombat]

Monday morning would be a good time to escape no?

[@BungleZippie]

malkycombat hehe. they have a complete lockdown at that time so it would be very difficult. Although the siren would go longer if that happened so people would know. But it's unlikely.

[@bluecylinder]

The best bit has to be @ 3:09 Thanks very much for sharing.

[@LaserGazerMan]

What is the song used in the intro

[@rotaryrevor4756]

Also for all the not informed people, Matt didn't leave one camera in bracknell and another in bagshot. What he did was record one of the sirens and then next Monday, he recorded the bagshot siren

[@mrmattandmrchay]

+tornado siren recorder/hking123456789 yep. I would never leave one camera and drive to another location. All were filmed individually then edited together.

[@Roostertailin]

Siren B is a bit tired...10 second windup...

[@thefaithfulphoenix227]

I work in a school very near there and we have siren on site! In the policies and regs there's even a Broadmoor Procedure for the school, should the worst happen!
