I think it's obviously a problem with the left solenoid as the one on the right is clearly working fine. It could be that it seized and they just decided to only use the one side, hence the pulse but then you can almost hear it clunk shut at the start of the test so I don't know but I wonder if that's it on permanent pulse now lol 🔊🤩

analysis time you can hear at the start when the shutters open that one of the more dominant notes from it opening is a c#. while the shutters are closed, you can hear what i used to think was the motor whining actually usually starts around a c# and lasts until a c flat, which suggests the shutters are the actual cause behind the whining. you also usually won't hear that whine on any other siren without shutters. this suggests that, like another commenter from another video on one of the broadmoor sirens said, that whine actually is the shutter experiencing resonance. my theory is, as the siren often tends to shake while sounding, years of that will cause more wear on the screws and/or the holes that hold it in place, that connects the stator and the shutter, which causes more whine overtime. this is likely why you can hear a lot more of that whine on the lanark siren, or any of the broadmoor sirens (aside from the trl and crowthorne station siren)

At least we know what broadmoor’s CS8’s originally sounded like when they used Pulse as their signal from 8th December 1952 (when the first test was conducted) until the 60’s

This is wicked. Love the sounds the solenoids make when they’re both shut, even more prominent on wind down too. Great catch! :)

yesssssss !!! like this,what this stop and start 😅😅😅 ha ha ha ha ha ha ha ha ha 🙂🙂🙂.

Great video, nice to see there are other siren enthusiasts out there! I have a collection of small sirens, they are loud enough, but nothing like this :)

hope this siren is repaired soon if its not already ?!?... though random interesting note i just realised this is probably the first siren to do pulse since the 50s/60s :0

This has got to be a pre-programmed signal, if only we could see what the inside of that control box looks like. I heard this one was broken a while back? Seems like they've messed it up a bit when they fixed it, absolutely love it though!

It's strange, every pulse and gap is exactly 3 seconds long, so maybe this is one of the sirens pre-programmed signals?

Wonder if this will do an 8 minute pulse for escape or just the usual 8 minute continuous tone 😂

i bet carstairs a few decades ago was like "ok in these bushes is a good idea"

correction: the high tone shutter is jammed open.

They should the pulse sound for the alert

So this the first recording of any 10/12 port coded siren in pulse! Even 3T22s weren’t recorded in pulse

I like how you can see the shutters closing and opening

The silver street thunder bolt but it’s it’s in Scotland

Epic. They ought to leave it as it is. It makes it unique a bit like Ravenstruther!!

What in the hell? Sounds awesome nonetheless, great video!

This signal is almost similar like broadmoor escape signal

They remind me of that high pitched 3t22 in clyde ohio

Amazing 😍👌 wish I was there but stupid school is stopping me 😒

I thought it was working for a second

This is really strange! I've never heard of a CS8 doing pulse. I would typically think it would do Hi-Lo instead. Not a lot of dual rotor sirens here in the United States do pulse either, unless they're programmed to do so. I personally think they should keep it this way, it sounds a lot more unique. I am still curious as to how they would have fucked it up like this though.

And thus is a first for me cus the last time I heard one of these it did attack the hi-lo never I my life have I seen one do pulse

@solidsabeye the Tbolt 1003 can do pulse right

Are the other CS8s alternating?

Wow

wait, broadmoor still keeps their sirens just in case, will they give it to carstairs when they decide to take their sirens down?

I think the 1:25 is a scary rundown

I ment to say I have never heard 1 of these do pulse

Sounds awful, but epic at the same time! Thanks for sharing!

Is that CS8 underpowered? It sounds kinda weird (not talking about the pulse) Or is that normal?

So ur telling me it’s tryna do high low? But it’s pulsing bc of 1 solar noid being broken?

What is the difference between hi lo and pulse

Are they testing Hi-Lo now?

What's pulse tone for

Something is not spinning right

11 MONTHS AGO ALREADY!

Did you control siren g

Did you enjoy the test? 😁😁😁

It may have been done on purpose due to noise complaints idk

Chance of this happening is a 1 in 1,000,000

Why siren g is escape see all clear tone is use
