ABOUT THE SIRENS:
Broadmoor installed 13 sirens in surrounding towns of the Broadmoor secure hospital, to warn local residents of a dangerous person that could have escaped. Broadmoor is a hospital to some dangerous patients.
The sirens were tested at 10am each Monday and I have separate videos for most of them sounding.
THE SIREN HUNT:
Initially these were quite hard to find, but we found them all. Some in council depots, compounds, parks and believe it or not - in the middle of housing estates metres from houses! 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 tone, the airflow is cut alternately (about once a second) 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 carefully.
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 The copper telephone wire system is outdated and parts have not been available for many years now.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.
• Broadmoor Sirens - Loc...
After a lot of meetings and consultations, it was decided to maintain the existing sirens as best as possible then remove them when they fail.
Bearing in mind that security at Broadmoor has been vastly improved since it was built, and the sirens were installed in the 1950s, and now 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 were be removed. Here is one being removed:

A new siren will be installed on the new hospital, which doesn't sound that interesting (electronic, not motorised).

Siren: Don't say they didn't warn you.
These aren’t used nearly enough in horror settings. The noise is so extremely unsettling and makes my fight or flight response go crazy
The fact that it's called "escape tone" too really messes with me, but it's so interesting to watch
Yeah going to school next to it isn’t ideal lol it’s fucking terrifying
@@amymay24 they're using an old school air raid siren, as a "prison break alarm" system?
For me it's just nostalgic haha, it reminds me of home

5:34 escape tone siren B
Lol it's kinda like a cop car XD
What's the difference between the escape tone and all clear? They sound the same to me?
@@AshleesBathroom the escape tone has the "Hi-Lo" sound from the shutters opening and closing on the sides of the rotors, whereas the all clear tone is just a full blast with the shutters open
2:33 bagshot u forgor the KLICK
5:34 and 2:35 is Actually Siren L
5:40 interesting how the flap opens and closes to create the two-tone
With the CS8 its not changing the hi lo, all the shutter is doing is muting that side, if you stood in front of the machine so both sides were facing to your right and left, the hi side would be on one side and the low the other, when the siren is going hi lo hi lo its just alternating the shutters on each side alternately, in the all clear tone its just opens them both, and when running down it closes both which is why the noise gets a lot quieter very quickly, if the unit was properly functioning... the bagshot siren wasnt and the low tone was stuck open.
@MythicalTwist3r Yep it is called hi-lo.
2:34 I love the windup of this KLAXON CS8!!!
There’s something strangely fascinating about old rotary siren I guess you could think of them as the faithful old sentry always on the look out ready howl they warning at the first sign of danger
“It’s fine, they test the sirens every monday.”
“It’s friday”

The bagshot siren sounds like a thunderbolt 1003t at 1.5% speed
Volume up is best ! :)) .. great video thanks for sharing. It will be sad when they are gone.
For all those asking what would happen is someone escapes at 10? The sirens would keep going. Since the test is only for 2 minutes then it will stop. If someone escapes then the siren will stay on escape tone for more than the 2 minutes thus alerting of a real escape.
In almost 40 yrs of living in Frimley, I have never heard the all clear sounded BEFORE the escape siren. I've seen the other towers around the area, but I'd always thought they were mini tv, radio or phone masts! Now as a higher functioning autistic, I at last know where "the sonic enemy" really is1 Good for me to know!
Excellent!
Excellent mate! Wish we had these in oz, might hafta cast and machine one. Great video!

I've been wondering when your next siren video would be released. This is a great one! ... nice to see the Crowthorne Station Siren close-up.... looks kinda spooky under that weather condition.
+Ow3n Lifts It was so foggy in the morning, that I did wonder whether the footage would be any good. Seems to be ok though. Thanks for the comment!
@@mrmattandmrchay would these sirens do a wailing signal [like the attack tone used in the Blitz] in the unlikely event of a tornado or other weather emergency?
There are similar sirens here. Tested on Saturday 2pm. Scary as hell when they start up in the middle of the night...
+MatzeGamer I bet all motor powered sirens will freak anyone out if they woke you up in the night. One of these sirens is inbetween two houses! See near end of video... ruclips.net/video/okxIDvfiyVQ/видео.html

I Just Love The Intro Music! Great Job On That!
Thanks for this! My son, aged 4 requested a video of some sirens and hey presto here you are! Thanks so much, very informative ❤
Oh brilliant! Does he have an interest with sirens, and alarm related stuff? When I was about 6, I loved wiring things up and taking things apart to see how they worked (especially my toys, then couldn't put them back together again!!). Later when I was about 10 or 11, I developed an interest in alarm devices - bought many burglar alarms and detectors - my room was wired up with so much stuff (goodness knows how I got away with it in my parents house!).
Unfortunately, the only siren system simular to Broadmoor is Carstairs in Scotland (still working). Might be a bit scary for your son as he's only 4, if you went there. Broadmoor sirens were removed back in 2018. Let me know if you have any questions from you son, and I'll try and answer them! Matt
sounds like an escape tone & all clear
You could not have shot this in a more creepy place on a more creepy day =|
Ok

The Train Station Voice At 0:49 Is Saying "The train now approaching platform 2 will not stop here, Stand back from the edge of platform 2, the next train is not scheduled to stop."
They sound like a thunderbolt 1003 doing hi lo but slower... :p
Love this video. Wish I'd visited them whilst they were still working.
1:40 I love this one! It sounds so good!
Well done on putting these videos together. Must have taken some planning and patience to capture these.
I was working on a long term project at the time in Reading, so sneaking out at 9am on a Monday managed to work out perfectly! But yes, it takes a lot of commitment and not forgetting that on average only 2 out of 3 visits were successful (other times the siren I visited didn't operate!) Thanks for the comment.
bravo!!
My friend actually got a hold of that cawthrone siren now.
The jammy git!
After years these never get old
In my town, San Bernardo, Chile this sirennes is used by firefighters to notify 12AM any time. A northamerican friend, first time in my town, believe this was an Atomic attack alarm and run to keep secure and cover before to hear it.
haha!! Well, I've been told a few stories about new residents in the area of these sirens have to find out the hard way about what they are. You'd have thought that as they have been sounding at 10AM on a Monday since 1952, that everyone would know about them!
Only just noticed that the Bagshot one has its low tone shutter stuck open, and the fact that the sirens have opposite faults! LOL
wow almost 15 minutes before the siren has shut down in my country it takes 3 minutes and it is all over
+Colin Sterken (colauto123) He explains in the video that they are all tested at one, for the video they are shown separately so you can see each one. Hence the time clock in the bottom corner showing you the actual time when the specific siren was filmed.
Yeah im guessing you either have electronic sirens or sirens like thunderbolts that have a quicker wind down than Klaxons
mr some 1 klaxon is a brittish built siren hebdenbridge has old war sirens posed as flood sirens this siren relys on friction
Annie McCarthy
No XD. I wasn't talking about klaxons If you look at the comment I was replying to you will understand
yeah yeah aint got time right now
busy playing candy crush soda saga still
I love the border Moore siren it sounds great 👍
I'd love to walk up to 5hat quite siren and kiss it literally kiss these life savers
i'm pretty sure they kill more people by giving them heart attacks after the surprise of them turning on for testing than saving them from any bombs or nut jobs from broadmoor hospital XD
Well done - wow, I've learned there was 'Lift enthusiasts' from your channel; now I've learned (from no less an authoritative source than Wikipedia) that there's such a thing as a 'Siren Enthusiast'!
Haha, soon you'll find that there are enthusiasts for anything
These Broadmoor sirens are amazing, I live near the Carstairs hospital sirens, well, the closest siren system near near me.
Nice
something i've noticed with a few sirens like the bagshot and trl sirens is that they're directly mounted to the pole instead of having some kind of support
Yey new vid ;P
Hello and I’m back with another update on the Bracknell siren! Unfortunately it seems this week the low tone damper was stuck open. At first I thought it was sounding the all clear first like it did once but I heard the high tone alternating. New to this week though as I heard it operating fine from my English classroom last Monday.
Edit:looking back at the recording it seems it was actually the Wokingham siren(the one near the shell garage). I will have a video up on my other channel called British sirens
Richard Marshall which is this channel here
I'm now inclined to believe that I've kinda figured out how the telephone activation system worked, and why the telephone box remains on the other sirens that have been cut down. The telephone control boxes, along with the equipment inside of them, are owned by British Telecom. Because they are property of BT, Broadmoor can't even open those boxes without BT's permission. This is one of the reasons why the control boxs are mostly left. The biggest reason why these control boxes remain, is because of their location. It serves no benefit to BT to physically remove the boxes, as it would require work to sometimes dig up underground phone lines, which would be of no benefit to BT and would cost a lot of money to do. With this in mind, the Cock-a-dobby siren site still has that mysterious 4th box in the back corner of the compound. I believe this to be a telephone junction for the surrounding houses, as well as where the sirens dedicated phone line comes in, so it definitely isn't going anywhere.
Now let's talk about what's inside the control box. Because the sirens produced three signals, a simple ring down circuit can't be used. Because of the age of the system, this leaves the possibility down to something similar to the old Carrier control units that were scattered all over police departments across the UK that were used to warn of air attacks. This system activated with a tone sent over telephone lines and worked similarly to a simple ring down circuit, with the only difference of course being the tone instead on ringing voltage. Now since that tone would only engage one contactor for as long as the tone is present on the phone line, the system alone wouldn't be able to activate multiple signals, especially a special signal such as the escape tone.
The most probable way is that their are 4 of these tone receivers in the telephone control box, each independently activated by a different tone frequency, but connected to the same phone line. These receivers are basically the size of a smartphone, so that box would seem oversized for 4 recievers, which lead me to believe that also inside the box is a latching circuit so that the phone line doesnt need to have a constant tone to continue siren operation. Reciever 1 would be the escape tone. Reciever 2 would be all clear. Reciever 3 would be the cancellation circuit.
For example of the tones used to activate the signals:
a bursting signal is used to wake up the phone lines or "prime" the lines. This was due to the fact that loss of the signal could occur if it was sent too quickly, so the recievers are woken so they are actively listening.
Escape: After a few seconds of this priming, a tone (let's use 1700hz sine as an example) would be quickly sent over the phone line. This tone would activate the escape tone relay, and the latching circuit and timer, and would activate the various relays in the small relay box. After the timer cancels out after 3 minutes, it closes a circuit in the cancellation circuit and stops the siren.
All-clear: the same thing as escape only with a different tone (say for example a 400hz sine wave)
Cancellation: when the specific cancellation tone is received, it activates the cancellation circuit, which de-energizes the latching circuits, and shuts the siren off.
Test: when the specific time for "test" is received, it most likely closes the "test" loop-back relay in the mini box, as well as operates a short 3 second timer. The test works by sending the test tone through the phone lines, and having it loop-back to Broadmoor in a hopefully pure sine wave to indicate a successful test of the telephone system.
Because of the test function, it's obvious that each siren has the potential to be activated individually.
This is all speculation of course, so i can't be sure of it whatsoever. Even though the system has been decommissioned, Broadmoor still isn't ready to officially reveal the activation system, most likely because similar systems like Carstairs still exist and it would possibly be a security issue, and also because BT still might own the activation system, Broadmoor might not know how any of it actually works. I've based all of this on my prior experiences working on sirens, as well as my knowledge of telephone systems, but once again I can't be certain for sure.
also I’m inclined to believe that the controllers were replaced or updated in the 60’s as broadmoor switched from
pulse to Hi-lo after the home office retired the attack warning grey (Fallout expected within 1 hour). Now back then how hard would it have been to switch them from Pulse to Hi-Lo, surely it wasn’t an easy task?
@@BritishLifeSafetySystems wait they used to do PULSE? *I NEED TO HEAR IT*

These sirens are almost like the thunderbolt but the thunderbolt winds down without the solenoids shut
they are basically British 3t22
@@CazicTheProtogen agreed
this is the longest Ramadan I have ever heard on a siren
I know that they’ve been removed, but do any remain? And does the one in Crowthorne still stand? I was at the station the other day but didn’t look out for it so didn’t see it, but I think it’s really interesting mainly just because they’re creepy as fuck
Surrey Heath Archaeology & Heritage Trust? I used to belong to that place. They used to be at 63 Bagshot High street, behind the library. I used to dig with them at South Farm, in Lightwater!
Hang on a minute... 1 siren at the London Road, one at Bagshot railway station and one at Crowthorne? Er.... Does that mean Frimley's right in the middle of it then? That does explain why the sound seems to come from a different direction, depending on the weather conditions. Is this a triangle shape, or are there any other siren posts I should be aware of? (Making it a square.)

@@mrmattandmrchay G is still working flawlessly. Highly recommend visiting!
That’s a klaxon CS8 cool video
At 4:35 the sound of the wind down was my fav
Our siren needs like 2 minutes but we only have 1 tone tested every saturday at 12am
But one war-siren test on october 1st
how are these activated? are they all hardwired or controlled by radio?
These are all hardwired, using telephone lines. The system dates back to the 50s and 60s. The telephone line wires were diverted to go from siren to broadmoor controllers. I do have a video showing one of the telephone lines and where it wire back to (local cabinet) which I may upload soon.
Man, these sound cool, I am actually sad I cant go see these things. I cant take a flight since I cannot do it as it would require one of our family members working in the UK (which is highly unlikely, as we are in the USA). And second of all, I would get confused as its a whole other world over there, and I work according to my schedule which might get messed up being over there.
You won't be able to see any of them working I'm afraid. They are all being scrapped.
Sounded like the Bagshot Depot signal had a stuck shutter. I could hear the lower pitched tone the whole time.
Is one side of the siren stuck open cuz that's what it sounds like.
Yes one side is stuck open.
Like you r video
Are the shutter going opposite when
Escape tone
I. Never knew there were sirens in the u.k thought it jus USA and may I have the name of that intro music u show
The cworthwone siren has a fault and i think the high tone shutter is jammed open do you think im wrong or correct
crowthone is my favorite, but it takes a bit of a trip.. I'd usually take a few weeks of normal activities before just going out to hear it
Secifically for the busted shutter
+HawkEyes Moments (Dave) i never know which ones are working and which ones are not these days. If I'm working nearby on a Monday then I pick a location and it's about 50/50 if it activates. Then it becomes a complete waste of time when it doesn't! !
I feel bad now
Near my house there is a Broadmoor siren used to change shift for the company workers in night it starts like an beast well I closed all doors and windows so I can't hear it anymore xD and it gets tested in morning with all clear tone first and escape tone
take the drone and put it on the siren when it goes off. that would be awsome
Yea or fly up next to it
if a drone fan was to by mistake go into the gap & the siren activated thats £500 worth of drone loss & big trouble for secure hospital siren tampering or if the siren broke he'd be held responsible
Seriously? There is no way you will get a drone stuck in the rotor. If you tried to get through the intake the bird screen will stop it and the damper will stop it also because it separates the intake into two and the drone won't fit. Secondly the output ports on the siren will blow the drone away stopping it from getting caught. But if the drone did get caught in the ports then it will no longer be a drone. The Weight of the choppers and the strength of the motor will obliterate it.
Unless it has a cover...
Hell yeah
4:35 is my favorite sound when the klaxon CS8 siren was running down
Where they are now, used to be the old Fire house! We found a skeleton of a robin in one of the cells, and we joked that it was doing bird!
Can these do a pulse tone?
+Bon Ron I thought so 2 but the thing is, is that I went to multiple sirens and non of them went off and the only 1 that went off was siren g (the one next to broad moor itself) so mabye they already have...
+InstaRage FTW The Hospital is currently building new wards on site and are knocking down old buildings. All the siren towers with the siren itself are going to remain until 2018 when work is finished at the Hospital. They will then take them down but at this current time, many sirens are faulty and my predictions are that Broadmoor will leave them until the time to decommission comes.
What is the range, and the decibels of this siren(s)?
The bagshot siren is my favorite.
Hi mr matt, would you recommend or know where I could go to find one of the sirens as tomorrow me and my dad are going to try and listen at 10:00am as we have always wanted to hear them close up.
Hi Joe. Oh no...! I think you are about 2 years too late I'm afraid. They were decommissioned about 2 years ago, and by the end of last year they were all physically removed. The only one that works now, is a new speaker siren in the grounds itself, but they test that 'silently' now. You best bet is 400 miles north! That's Carstairs, especially Ravenstruther (my favourite) - pronouced 'wren-stree" - that system is tested on the third thursday of each month, at 1pm. I know it's a massive trip but that's the only system of old fashioned sirens that still works. Broadmoor sirens no longer exist :( Give me an email if you want more information mattw.youtube@virginmedia.com
mrmattandmrchay what a shame, I've watched your siren videos for a while now and always wanted to go and listen for myself, but thanks for telling me this as you haves saved us a journey up to Wokingham, again thanks for this info. keep up the good work on RUclips though!
@@joegaskell18 you could try Devonport in Plymouth, they use CS8’s and GP12’s for a radiation leak warning system. Tested every Monday at 11:30am. They test them in Wail for about 40 seconds then go into All Clear for 15 seconds before switching off. If your standing in the right place, you can get a killer ambience, very creepy if you ask me
Broadmoor siren cool
Do you know why the bs siren does all clear tone first

bet all the people was looking at the bloke thinking "Why is he filming sirens for?"
haha, well its already happened!! See the guy sitting on the bench at 4:20 - he was also filming the siren on his phone and contacted me a few months later! When filming stuff like this, I concentrate on what I'm doing and forget everyone else around me. It used to bother me what people were thinking but now I kind of "blinker it out".
The ends of that thing literally look like my mom's hair dryer.

Hey! Could you please find more sirens? I am a huge fan of those videos.
Hiya, thanks for the comment :) Unfortunately there are only 13 sirens and I've done a separate video for each of them. I do have some more footage, but not much, that I will be uploading soon. Also, I am planning on doing an update on these sirens later in the year. But the things is, there is not much that I can add to my existing siren videos. I mean, I've shown where they are and how to get to them, the sirens sounding (in most cases) (by the way, that took months to get them all), so there is not much to add. I wish there was something else I could show because these videos have a lot of interest.
Hi mrmattandmrchay! I understand!
I'm getting so many people talking about siren videos that I may go and re-visit a few afterall! Not sure when but within a few months I guess
You’re so awesome mrmattandmrchay! Thanks! Do you have a vlog channel?
Where are these wonderful Beauties today?
What is the name of the music .. tryin to find it .. Nice vids
Hi, please see Q44 (first on the video) on my Q&A... ruclips.net/video/7y3xaEEcx6g/видео.html
The reason for the Bagshot siren not working currently might be because of the fault with the All Clear starting first which is not what Broadmoor would want since it suggests to the public that theres a real escape because of no All Clear following afterwards. Bagshot siren is due for decommissioning anyway so they probably just left it potentially with the power off.
+Bon Ron These were filmed on different days, so "just maybe" they did test it the other way round... seems unlikely, but possible. I love the bagshot siren for it's slow start up.
Can someone please explain what this would be used for ?
Hiya Tegan, 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. Hope that answers your question :)
Isn't the Sandhurst Training Station around here? Because if it was I would sound an attack warning during the test, as you never know something might happen to it. I think we should have them everywhere that has a military base. Anyone agree?
The Sandhurst Military Academy is not too far from these sirens but it's right next to Camberley siren.
I LOVE BAG SHOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
it fact the ct siren high tone is actually jammed open
The coast-down time for the CT siren is insane!! Must be ball-bearing motor?
+KJ Rivas the longest one I think took 12 minutes to come to a halt. Whereas one took about 1 minutes but on that one had a rubbing noise as it slowed. Still cool units and most date back to late 50s
All Motors will have ball bearings in them lol, the reason for the long wind down is because of the minimal air resistance in the other rotor which causes the other one to slow down quite a bit. It would take longer if both were closed.
But, siren C’s hi is jammed open
Erwin Besmonte no
Erwin Besmonte siren e
Such a shame that the Bagshot siren has had a shutter stop working since you last filmed it. Doesn't sound so good now.
+The_ALEX_ELLIS_Channel doubt it will ever get repaired now as well . I do love the long run up on this siren... still the best sounding airen out of them all
I work in carstsairs often
They test their alarm every 3rd Thursday at 10am if my memory serves me correct
Sounds the very same
We got a briefing on what to do if the alarm went off any other time
Ct siren I think has a shitted out solenoid so the damper can’t move so it maces it sound like a broken pulse
