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 The copper telephone wire system is outdated and parts have not been available for many years now.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).

[@compzac]

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.

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.

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

[@seanjuth]

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.

[@BritishLifeSafetySystems]

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?

[@childishtombino1275]

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.

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.

[@mrmattandmrchay]

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

Can someone please explain what this would be used for ?

[@mrmattandmrchay]

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 :)

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!

[@antcraft3590]

I can hear a continuous ringing sound!

[@Four-r8slol]

it fact the ct siren high tone is actually jammed open

[@jasonburnet9181]

The running down at Bagshot sounds like a train slowing down

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

[@L.I.Thunderbolt1003]

I wish these were in the states 😟😞

[@mrmattandmrchay]

Get over here quick!! You only have a year or two left and they'll all be gone haha!! Try and get your parents to come to "sunny Bracknell in the UK". Plenty of stuff like, uhm, building work and SIRENS!! HAHA Thanks for the comment

[@sadasivamsivakumar3488]

Those never die in India but only existing in Tamil nadu only 2 or so

[@lespearce2684]

I have one of these in my garage

[@lespearce2684]

See my channel

[@JetDom767]

Do these ever sound the rising falling warning that some of the Carters and Castle Castings sound in Lincolnshire and Yorkshire etc. to warn of flooding?

[@meesguyy]

Dom757200 no

[@Engineer_Anton]

The hi low escape tone better than 3t22 also 3t22 is only found in usa btw!

[@Benicio_Fols]

That’s a klaxon CS8 cool video

[@sgtscott8900]

ideally they should only be tested in all clear tone and only reserve the escape tone for an actual incedent

[@cjmillsnun]

+sgtscott8900 Completely disagree. Because the escape tone uses the flaps on the end of the siren to go high-low not testing it will cause them to seize, the result is an all clear tone when they want escape.

[@mrmattandmrchay]

+cjmillsnun Yep, I'm afraid I agree also :) Everything that's supposed to happen in an escape situation should be tested, else in a real situation the shutters may not do what they should do.

[@seewdshakr]

damn i need to know how they made this..the motor is extremely crazy strong as fuk

[@CazicTheProtogen]

some sirens have stronger motors (some up to 50 hp)

[@VonnaWasser]

CS8 Sirens established in 1952 1952-2018

[@BritishLifeSafetySystems]

They were first tested on the 8th December 1952 and were tested in Pulse as the Home Office was using the Hi-Lo signal for Fallout Warning Grey (Fallout expected within 1 hour) but once the Home Office deemed it no longer necessary and retired it, then broadmoor adopted the hi-lo signal

[@JerriS.]

I LOVE BAG SHOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[@kjrivas7419]

The coast-down time for the CT siren is insane!! Must be ball-bearing motor?

[@mrmattandmrchay]

+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

[@childishtombino1275]

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.

[@TheMNrailfan227]

It sounds like a 3t22 losing volume.

[@Engineer_Anton]

5:33🎉 hi lo! Rotaters start to spin makes good note! Escape signal klaxon low tone shutter stuck im watching!

[@tirbeaverroblox5604]

crowthrone and bagshot is one of my favroetes

[@mineolabolt4928]

So sad this was removed only siren g remains but later soon it won't...

[@e.j.thomas9994]

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.)

[@MontisEinsatzfahrten]

hat is so fucking great I love it...one time I drive to this town and film this great sirens self...great video! ASK: How many sirens standing there...? Best wishes from germany Monti
