Secomak CS2 Air Raid Siren
HTML-код
- Опубликовано: 5 окт 2024
- A video testing my newly-purchased Secomak CS2 siren. A VERY rare siren, which I currently believe is the only CS2 in existence. (I thought the same with the Klaxon SS6 at the time of its purchase, and now look where we are!)
According to the previous owner, it was employed at the Birmingham Battery and Metal Company's works in Selly Oak, where it was mounted on one of three chimneys on the site. While its exact use was unknown, it was likely used as a shift change siren while doubling up as a warning/air-raid siren for the town of Selly Oak. The siren was audible all across the town. It was removed in the 1980s when the factory closed, and was kept in a garage for much of the following three decades - ensuring it has remained in a very good condition despite its age.
Secomak's GP2 siren was essentially a single-ended version of the dual-tone GP3, with some modifications to the junction box and mounting bracket/base based on the shape change. Manufacturer documentation suggests the siren output 123dB at 1m, and could reach 102dB at 100ft away. The only real difference between the GP2 and the CS2 recorded here is the addition of a 'coded shutter' to the end, which opens and closes to allow or restrict the flow of air into the rotor. This opening and closing has a damping effect on the sound produced, and allows for different signals to be 'broadcast' to the surrounding area.
On 415v CS sirens (CS6/CS8/CS12 if one exists), the solenoid used to open the shutter is powered via a separate 240v supply, allowing for independent control, while on 240v sirens (CS2/CS3) the solenoid gets its power from the motor's power supply, so turning the siren 'on' opens the shutter, and turning it 'off' closes it again. This does limit the range of signals able to be created in comparison to the 3ph 415v sirens. However, while I could create a separate 240v supply for the shutter and then be able to create far more signals, this would spoil the originality of the siren and as such will not be happening.

Not quite sure I’d say that 0:49 is escape or hi-lo because neither applies - it is simply a pulse.
This siren is single-tone, so hi-lo is impossible, and it was used on a metalworks, so there was no concern whatsoever about escaped lunatics 😂
Ok
ill fix that
Very interesting and what a gem! Amazing unit.
Thanks for watching Matt, been a while! Hope you've been well.
The CS2 certainly is a rather unique siren - currently the only one out there to the best of my knowledge - and it's in great condition considering its history.
One day I might do a shutter operation video for this like your one from Broadmoor - this one's far less complicated than a CS8 though!
@@al66class59 can you please make a video of the tag of the cs2
@@liamemmaairraidsiren9046 if you mean the shutter I have said I might in the above reply, but I can't provide a timescale for when
@@al66class59 ok thanks
now we need a cs6
That I can do! I will be doing a video of mine doing the following signals:
• Alert
• Wail
• Fast Wail
• Pulse
• Pulse Wail
Really 😃😃😃😃😃
@@BritishLifeSafetySystemswan are you going to be doing the video.
@@liamemmaairraidsiren9046 when I have three phase power
Ok
What a unique siren. Had no idea these existed
Neither did I until it popped up on ebay. Bought for a bargain price too, sold for far less than a conventional GP2 would go for!
@@al66class59 I've already got a hand crank siren for a cheap price, so I might try and get me a bigger siren!
@@CycloneJoey518 we own four sirens; GP1 was unsurprisingly least expensive, then the CS2, then GP6, and the SS6 cost us the most. The CS2 and GP6 were ridiculously cheap based on prices of similar, and more common, sirens... paid a combined £672 for the two, even if they came two and a half years apart
@@al66class59 were can I get a cs2
Got this off eBay. Good luck finding one though…
This is the only known existing example I’m afraid
Now THAT's cool, awesome acquisition!
Thanks! Third siren I’m really proud of in the collection. GP1s are cool but common (though mine has a Secomak 50th anniversary sticker on it), however SS6s and GP6s are both so rare in private ownership that they feel quite special to own!
MY LORD ITS A SNAPPING TURLA
OMG this is incredible 😍!!!!!!!!!!! So cool can you please make a video on your GP6 siren.
Well he can’t as he doesn’t have access to 3ph power
Ok
@@BritishLifeSafetySystems do you now how to drill run a cs6 siren
@@BritishLifeSafetySystems Because I might get a cs6 siren
@@liamemmaairraidsiren9046 yeah good luck finding one as they are rare to come across
That's some nice wee siren you got there! 🤩
Four and counting now in the collection - you may notice I've only recorded three and that's because the fourth requires three phase power which I don't have lol
take good care of it, it is very rare
All the sirens are my favorites
Whoa, that's a yt first! Also to achieve a good pulse signal, you could wire the shutter to a separate cord(?)
I could, but I don't feel like doing that; it's both more complicated and spoils the originality of the siren. Mind you, it's not like my ideas for new paint would do the originality any good either!
@@al66class59 okay well, it's just a thought ¯\_(ツ)_/¯. Cool siren either way!
Great to see one running
THE one. So far the only extant example! Who knows if we’ll find more…
But yeah it is good to have it running as GP/CS2 videos are very rare
@al66class59 can I use a picture of your cs2 please
Sure - just as long as I'm credited, that's not a problem. RUclips didn't notify me of this comment at the time, so hopefully I'm not too late!
@al66class59 ok thanks I now I'm a little late 🙃 .
that damper tho, nice!
yeah it is cool! quite substantial too, cover about the size of the newer iphone se and five or six of them thick is the best way I can think of to describe it
It Sounds Like An Federal Signal 2001-130 Almost
wow it sounds like a 2001-130
Nice one mate!
Thanks!
Love the dampers
How many volts does this take to get full power?
240v 50Hz
@@al66class59what about 120 volts at 60 hertz?
@@CJP_Productions would probably kill it
@@al66class59 how?
@@al66class59 what about 240 at 60 hertz?
That tsirenhas no coast. Even w
ith the intake damper, the coast is still pretty much quick. So a damping plate for what?
To decrease the output volume of the siren on wind-down by vastly reducing its air intake, and hence its air output. Wind-down speed likely wasn't a concern, and due to the low armature mass/small bearings, it was always going to be fairly quick anyway.
It would also allow it to produce different signals, but the shutter/damper is wired directly to the motor so there aren't many options.

Looks like a cs8 but with 1 solar noid and 1 siren
Mini cs6 siren
XD
Great vid!
Thanks! To be honest, considering the attention CS12s get for not existing, I'm surprised CS2s are/were so little mentioned! Bet it'll all kick off now lmao
how large, how loud?
Decibel rating not sure, I tested this indoors and was multiple rooms away from the room in which I put the siren. So clearly loud enough to warrant me running away from it! I did have a document with the manufacturer's sound ratings at 1m but now cannot find it.
In terms of size I'd say about 5-6kg and a foot long from end to end, shutter to motor. If it helps at all, the solenoid box is almost exactly the same size as an iPhone 8 in length/height (but obviously has a much higher depth)
WOW!!!!
A baby siren ?
Je remarque aussi la sirène G de l’hôpital de castairs ne sonne souvent presque plus elle a pas sonné le jeudi 19 mai 2022
Carstairs sirène G sonne seulement une fois chaque mois
wow what an annoyingly high pitch siren to have. congratulations on somehow buying this little thing that i didnt even know was real
only one extant so far! it really is irritating so i havent really used it much since filming this lmao
mini cs6
Wow, looks a lot like an F2 Sentry. What port is it and how noisy is it?
Volume I can't remember exactly (I had manufacturer spec somewhere) but it's loud enough that I was on the other side of the house when testing - and it's 6-port.

its so cute❤🩹
Vidéo intéressante essayer de faire une vidéo avec un CS6 ?
Malheureusement je ne possède pas une sirène CS6 mais si je vois une cs6 sur un bâtiment ou dans le propriété privé, je le recorderai.

Oui. Les sirènes CS6 sont très rares mais si je peux, je recorderai un cs6. Aussi vous pouvez regarder la chaîne RUclips «British Life Safety Systems», il possède une sirène cs6.

0:65 Flight
That would mean CS1 CS2 CS3 CS4 CS5 CS6 CS7 Sirens do exist and maybe CS9 CS10 and CS11
Not exactly. Secomak/Manufacturer brochures list GP1/2/3/6/8/12, but only CS2/3/6/8/12. GP1s were too small to make shutters for.
GP/CS4/5/7/9/11 have never existed, and Klaxon introduced the GP10 later (but I don’t think they offer a CS variant as they’re out of production).
@@al66class59 later klaxon brochures show a CS10 model. I can confirm this

@@al66class59 thank you
Nice! Also, dumb question, but how do you activate the CS2? Ive been trying to activate my CS2 for a little bit.
Please don’t ask him to make a video of it. I currently am painting it grey. Im also getting it an ms 390 motor because the other one is toasted. So is the shutter.
Another CS2? You sure? I know other GP2s exist but have neither heard nor seen another CS2. And certainly not one in the states either!
They work when current is passed through the motor. I can switch mine on by plugging it into the wall and turning on said plug.
@@al66class59 yep. He has one. I didn’t know what it was until I watched this video and saw the metal tag. Hopefully you know what i mean by “metal tag”
@@Thunderbolt_7026 wait, the motor was toasted? No wonder why it didn’t activate!
Although unfortunately I can’t find a way to control the shutter. I think i just might manually move the shutters. But that’s kinda dangerous, because theres a spinning fan inside.
