It doesn't matter how much money you try and throw at the guys removing the siren, Even if you offer more money than it's worth than scrap value they'll still take it to the scrapper
So here is what I can see. A solenoid pushes a hinge (on kind of a doorhandle of sorts to minimize pressure on the solenoid. The turning point of the hinge is where the flap is connected. The hinge is held in a position by a spring. This holds the flap in a closed position. When the solenoid is engaged it moves back, the hinge moves and flap opens up. This is operated to a timer relay. I do not think that this is a great explanation. Matt, would you like me to create an animation of this or a practical demonstration with a functioning mechanism? I am very happy to help. Plus I can subtitle this video for you.
To accurately work out the times they’ve opened and closed, the first test was on the 8th December 1952 at 10am They used to do pulse as the home office was using Hi-Lo for fallout warning grey (fallout expected within 1 hour) But once the Home Office retired this signal, broadmoor switched over to the more infamous Hi-Lo signal we know today
My girlfriend’s 23 year old sister made a POINT of being weirded out by my interest in sirens when it came up in conversation. I love this though, definitely more going on in there than I thought!
Couldn't they use those sirens for natural disasters or civil emergencies? Our Civil Defense system in the US was repurposed as natural disaster sirens.
Interesting to see inside that mechanism. If the siren dates from the late 50s, then it must have been moved onto that particular roof half way through its life, because the shopping centre was built in the 1980s (according to Wikipedia and the architectural style of the building). I wonder how long it was out of service.
According to some people that I've spoken with, it was originally on the council offices. You're quite right that the shopping centre appeared way after the siren was first installed.
@@mrmattandmrchay did you know that the old 2ww sirens had shutters. Not all of them but in some places on the south coast they had gents and carter sirens with shutters in WW2. They sounded what was called the cuckoo signal because of surprise attacks on the see front by German fighters but still sounded the code red and raiders past signals so they must of sounded a faster hi lo sound than the broardmoor sirens
So these really are basically a horizontal Federal 3T22 in the way these operate...of course these were in service long before the 3T22 existed so I wonder if Federal Signal got the design from them or just tweaked it a bit...
The solenoids are similar to the ones in an American Federal Signal Thunderbolt 1003, but the linkages have to operate rotating butterfly valves as opposed to sliding valves.
Love this old stuff I really get a kick out how simple things were back then but I’d say it’s overdue for re greasing still I suppose maintenance Is difficult when parts aren’t available anymore.
That was maybe three weeks to a month go. I was invited (as I know both Michal and Matt) but was unable to go due to family engagements. Apparently the only ones left now are sirens F and G which haven’t been removed, but nobody knows for sure.
I hope these sirens aren’t destroyed when removed. It would be great if they used them for something else. You should see if you could buy one off them
Hi Noah, It's not as easy as that. These are not the type of thing a high security hospital will give away. I did ask about 4 years ago, and the answer was always no.
Well it looks like a Federal Signal 3T22, or Thunderbolt 1003 solenoid, but a 1003 has smaller solenoids. And this siren has a lower pitch than a Federal Signal 3T22, probably bc U.K's alternating current frequency is 50hz so the motor spins slower and in u.s is 60hz
What's the point of actively removing a siren just to run the decommissioning program? Why not just cut the power connections from it so that nobody can turn it on?
hey matt, i'm working on an informative video on the klaxon cs8 sirens. do you mind if i use some of your videos? i will give credit in the description. thanks!
Hi. Thanks for your message. Normally I'd have a look at your channel to see what type of content you're creating before deciding. If I allowed everyone to use snippets of my videos, then it'd get out of hand and my videos (which I work very hard to film and produce) would start appearing everywhere on youtube. This is why I don't automatically say yes to everyone. However, your channel has no content at all for me to make a decision on. Crediting me in a video on a brand new youtube channel, is unlikely to give me many (if any) further views on my videos. Therefore on this occasion, I'm very sorry, but I'm going to have to say no unfortunately. I do appreciate you asking first though.
Why don't they just use a gearbox connected to the actual siren wheel which picks up the siren rotation, and which then brings down rotational speed down to 3 rps (half a turn on 1.5 s) which converts to 180 rpm. Then just a mechanical linkage connected from that cogwheel to the shutter door.
Nope, despite many requests from many people they decided not to make any available. I can't blame them, if someone rigged one up and activated it, then the management at BMH would take the criticism from releasing them in the first place.
Depends on the location. Most end up in waste while either partially or fully assembled, left in a city's garage, or fully dismantled/destroyed for the contents.
When they were removed, they were all taken back to Broadmoor hospital. Many people asked, no-one was allowed. But it would be irresponsible of them to give them away, else people could power them up, create a nuisance and Broadmoor would be held accountable for giving them away in the first place. At the time, they were receiving so many emails 'can i have a siren' that I think they got fed up of the subject ;) I guess my channel probably didn't exactly help either.
Matt, i wonder why you not asked for permission to take both sirene and All control equipment with you home 😆 what about the Main controller, was you able to record a video of that inside?
Great video. It's very interesting to see that big electromagnet. Also, it'S RD. I made a channel with some videos on it. I will likely use this channel from now on. i just wanted you to know i'm the same person. Thanks for your Email by the way.
cool. Just a note, you could be limiting your video content by your channel name. I mean, if you upload Schindler, then it's not a Express? Perhaps I'm over-analysing it as usual!! :)
mrmattandmrchay Hmmm, you could be right. I’m not planning on only uploading Express lifts, just a thing old or interesting. I genuinely couldn’t think of a name. Do you have any ideas? Oh, and I think I found an amazingly rare lift in Edinburgh yesterday. It’s a Smith Major and Stevens lift which was modernised by Express in the 50s/60s.
@@Lift.Tracker That lift you describe sounds wicked! About the name, how about using the word Express as per dictionary definition: "express definition": 1. to show a feeling, opinion, or fact: 2. to communicate what you think or feel, by speaking. You could play on that by making it something like "Express lift interest", hmmmm I must admit that was a crap attempt you shouldn't rename it to that, but you know what I mean? I'll have a think...!
mrmattandmrchay Channel name changed! I don’t know why I didn’t just think of this name in the first place! Thanks for the suggestion to change it. I’ve got a reply back from the guy at BSM. He’s invited me to a tour of plant rooms, lift motor rooms, the basement and staff passages. Unfortunately it’s probably too late for you to come along, but I hope that you will be able to get the arrangement of seeing the lift motor room! :-)
@@Lift.Tracker That sounds fantastic! Your channel is showing some good content so keep up the effort. Always worth trying to go the extra mile then uploading it, rather than doing the 'short cut' and just uploading anything. Well, it's always been my way of doing things, as you know, I prefer to spend loads of time on videos to get a good reputation for doing quality videos. But this is just me, and you should make your channel what you want it to be. REALLY looking forward to seeing your BSM videos, but my advise is TAKE A WIDE ANGLE CAMERA AND TORCH! Would have liked to meet up and enjoy the experience with you, but how about making this YOURS and own it? - I mean, you made the effort to contact them, so you should get the reward and views? Let me know when it's up.
