Klaxon SS6 Air Raid Siren - Pre-Restoration Tests

- Disclaimer: Volume warning, this gets loud.
I'm unsure if this model name is official, but this is what the makers plate suggests. This siren was modified and sold as the ACA Sentry 95 in the US, under a deal with Klaxon. Nobody's ever found one in the US, though.
Two tests with the stator removed, essentially turning this into a centrifugal fan, followed by three tests with the stator fitted.
The restoration will include work to clean and repair the brass, minor electromechanical attention and a full repaint.
This siren was formerly owned by Scott Bullen.

YOOO YOU GOT A SENTRY 95
pretty much, its the same one as on the video 'Klaxon Air Raid Siren'. we bought it.
@@al66class59 that is a very rare and gorgiouse sounding siren
@@jezcolborne6329 indeed
@@al66class59 where was it from. Was iit an old fire siren for schools or was it for an air base as a scramble siren?
@@al66class59 or was it used for underground blasting in coalmines
I like how it just stops, instead of having to wait for a long wind-down.
Very nice harmonical sound
Technically this is the closest we'll get to confirming the Sentry 95 did exist, but only its original model by Secomak. (or Klaxon)
Nice video! Love the sound!
It's Klaxon. I don't know how old this siren is, but I'm not sure if Secomak existed (or at least made sirens) when this was made. The history of the two companies is far too confusing for me xD
You're right about the Sentry 95 link, this was (apparently) modified and sold under license from Klaxon by ACA. Not that anyone's ever found one in the US.
@@al66class59 Secomak was Klaxon’s original name. If you look on some of the older CS8’s boxes and tags, they’re branded by Secomak. I think they changed to Klaxon around the 70’s or late 60’s. And as for the age, ACA advertised the Sentry 95 around 1968 I believe. I’m thinking the SS6 is somewhere around there, probably around the 60’s is when it came out.
@@PyroTech4051 Done some research. Klaxon of Birmingham (who made the SS6 above - presumed model name) were founded in 1909. Secomak were founded in 1930. I'm unsure if the Klaxon still extant today that is based in Lancashire is the same company as the 1909 Klaxon from Birmingham, as there's very little information about the latter's full history.
Either way, a company called Halma purchased 'Klaxon Signals' at some point in the 1980s or 1990s and by 2000 Klaxon incorporated the Secomak brand. 2000 because that's the earliest year the Wayback Machine will take me to on Klaxon Signals' and Secomak's websites.
The CS8 was indeed a Secomak design originally (dating from around 1952, when Broadmoor got their first sirens). CS8s were still branded Secomak well into the 1980s and I believe some GP8s were even into the 1990s. However, following the Halma takeover of both KSL and Secomak, all the designs for the sirens were moved to Klaxon - and so by 2000, Secomak no longer made sirens. From then on, they've focused solely on air movement products.
TLDR
What it sounds like to me is Secomak and Klaxon were different companies and eventually ended up merged - but that assumes the Klaxon that made my siren is the same one that exists now. There's been far too many uses of the Klaxon name for me to be sure tbh xD
@@al66class59 Great to know. I think Klaxon is still around, and I heard they still make the GP8’s. Not sure if it’s true.
@@PyroTech4051 GP8/CS8 production was discontinued in around 2004/05. They only make the GP6/10/12 now, alongside the electronic range.
That sound is so satisfying
Completely agree!
0:38 that wind down sounds almost like a 3T22 siren
The noise it makes between 0:07 and 0:12 is really creepy.
0:20 and 0:25 too
ACA Sentry 95/Klaxon SS6 siren tests:
0:00-0:28 Wind Test (2 Blasts)(Sounds like a high pitched H.O.R. Si-Rex No.15)
0:28-0:46 Short Alert Signal
0:47-1:10 Attack Signal
1:11-1:27 Short Alert Signal (AGAIN)
Actually 0:47 - 1:10 is Fast Wail
sounds like a mini klaxon gp8, nice
Those are literally my favorite sirens, I would do anything to have one!
They're getting more common as people stumble across more and more of them in various places. Still, this is the only one in the northern hemisphere that definitely works!
If you do happen to find one somewhere, I would absolutely say go for it - but patience may well be needed given their scarcity!
That is the most wise speech I’ve ever heard about a siren. Also something I wanted to ad is that I’m in the US and there aren’t any Klaxon SS6’s here. I was thinking about taking a trip to the UK because there is one mounted on a high wall in an abandoned factory, I just wonder how I will get it back.
@@ston3pile540 I know the one you're on about - I am/was in contact with someone over here who has also looked at trying to get it down; removing it from the wall is a task difficult enough in itself given its precarious position, but to then fly it back to the States without anything being damaged is another kettle of fish!
Such a move would make an SS6 the first one over there; nobody's ever found a Sentry 95, which is on paper a carbon copy of an SS6 but with a shroud, as of right now- and I am not convinced anyone will. Mind you, apparently someone over there has a CS2 (which I didn't think was possible and still doubt so far, given I've seen no proof of it, as Secomak never sold anything to the US) but I am always happy to be proven wrong!
@@ston3pile540 3 in the UK including the one in this video, 4 in Australia, 1 in New Zealand, so far.
Total of 8 found.
@@HX56Musicnow 4 in the UK! Just found another and it’s on its way to coming off the wall right now!
Hey there, do you have the top part to the siren? Not sure if it would be a shroud or not.
The last three clips show the siren complete. Unlike the Sentry 95, this doesn’t have a top shield.
@@al66class59 Thanks, but still very cool!
@@al66class59 You could male one though!
I could, but that would damage the originality of the siren. I like it as it is anyway :)
I want to make a 3D printed model of one of these.
Do you know what the dimensions are of parts of this siren, like the rotor, stator, and base?
This siren looks like it might be small enough that i could 3D print a full scale working replica of it.
Do it! And i think the motor is about the size of a model A motor
@@That_2_guy2T AlarmMuseum is a gigachad and gave me dimensions measured from their ss6. turns out the rotor is 6 inches. siren stands 305mm tall (just barely over a foot) full speed the motor runs 5820 RPM. Motor base is 236mm (with the flange). Intake opening is 75mm. rotor height (top and bottom of ports, didn't include the height of the vanes) is 70mm. outside diameter of stator is 157mm (6 inches is 152.4mm and completely would make sense as the rotor size)
I will be using an XD775 DC motor for this full scale siren. i will hide a small pwm speed control circuit inside the motor base underneath (or inside the junction box if it ends up being large enough). siren will operate off of 12 or 24 volts DC. i'll figure that out later
@@nascarsimracing1 sorry, completely missed your original comment or I'd have given you them! hope the 3d printing goes well
(of course if you want a second set of dimensions for accuracy I can still provide them as I think his one remains in a slightly poor condition)
@@al66class59 yes, that would definitely help!!!! Thank you!
@@nascarsimracing1 turns out there's dozens of different dimensions I could give you which would take me hours to measure, but there are some immediate differences from what I have done so far:
-air intake 77mm across
-stator *base* 160mm external diameter and made from 1mm thick brass sheet
-stator slightly tapers in, and before it slants inwards to the intake, the diameter at the top is 156mm
-total height 311mm
-total width 239mm
I can get more specific ones later but those are differences to what you've had so far
Really cool! What is the dB rating?
Not exactly sure, but I'd guess around 120. Noticeable for sure!
That’s actually pretty good for what it is!
THE SENTRY 95!!!
Sort of- while not *officially* a Sentry 95, it’s as close as we’ll get. The sentry 95 design was essentially this, but rebadged from Klaxon to ACA with a rain shroud added.
Cool!
Thanks (and sorry it's taken 2 months to reply!!)
@@al66class59 No problem! 😀
Sounds a bit like the good old Carter WW2 Air Raid Sirens
Sounds like the ACA Sentry 95, I think it’s recommended to the other
This was its basis, so yeah.
What does it say on the plate? The plate on mine is hideously rusty and so far I’ve only uncovered a part that says Klaxon LTD. Also, under the plate, it should have KLAXON stamped into the terminal box
Hi mate, drop me an email al66class59 AT gmail DOT com and I can send you all the information I have, plus some photos of the current condition of my siren. I’d love to get some more photos of your recent acquisition too!
@@al66class59 sorry for the late reply this comment didn’t appear in my notifications! I’ll email! HX56 told me what it says on the plate but it would be awesome to see how the restoration is going!
oh yeah yooo she got a aca sentry 95
Very cool ss6 siren. Can you please tell me where you got the siren. Thanks 😊
Ebay
However, you'll do well to find another for sale as these are extraordinarily rare in the northern hemisphere - you'll need a lot of patience, and a lot of money if one does come up!
@@al66class59 ok thanks 😊.
@@al66class59 I got a DUPLO siren and do you know how many voltage it takes.
@@liamemmaairraidsiren9046 I can't be sure, as some of them were made 12v so they could be used by vehicles, and others at standard mains voltage (220-240v)
@@al66class59 do you know how many cs3 sirens are ther in the world
It sounds like a honk
You should add a top shroud and turn it into a sentry 95 lookalike
I could, though this basically is a Sentry 95 anyway. Well, it’s as close as we’ve come to one in real life as this is the British version - klaxon exported it to the US under a licence agreement with ACA.
As a real sentry 95 has never been found, I’m unsure how the top shield would fit lmao
@@al66class59 when i make my full scale working klaxon ss6, imma also make it into a full scale sentry 95!!
A bit of sheet metal and yellow paint will do the trick
Also what are you restoring on this siren?
Cosmetics- ie full repaint and brass polish. As can be seen, it’s fine mechanically
@@al66class59 oh yes it’s gonna look great I bet
It’s progressing well to be honest! Not quite exactly the same colour as it was, but I think it looks great now.
Still some work to be done to it though, so you’ll need to be patient for a video!
BRO NO WAY A SENTRY 95!!!!
well yes, but actually no. while it's essentially the same siren (klaxon agreed a deal with ACA to rebadge and sell it in the us), this one is klaxon so isnt exactly a sentry 95
@@al66class59 ok but still its Close Enough to one.
Sounds like a Carter air raid siren
yep!
@BehaTheSirenMan2009 yeah it's an equivalent port ratio so makes the same frequencies. 20/24-port sirens (eg Canadian "CLM" sirens) are in the same boat.
That’s the smallest 5/6 port siren I’ve ever seen
You’d be surprised. It is actually quite big! Id say over a foot tall and 11-12kg, it’s certainly not huge but not small by any means
I’ve got sirens that are smaller than it to say the least
@@al66class59 do a siren collection video
There are plans on the cards to do something like that. One of my four hasn’t yet been collected from its old owner, and a second, I don’t have enough power to run it (it’s a 415v 3ph) - then my other two are both on UA-cam already.
@@al66class59 I got somewhere a screenshot of the Sentry 95 brochure. It weighs 40 lbs and is 20" tall according to the specifications.
Those figures make rough sense, though that height would include the shroud (on the Sentry 95) which this doesn’t have. The SS6 is also more like 30 lbs.
Its believed that there is one in Australia too!
Yeah, I heard that! Never thought I’d see another one. Hopefully this one will soon be in something of a better condition than the Aussie one though
Actually I think 5 of them
@@SylvesterTheSupernatural16 Yep, thats true. Many more have been found, many of which, indeed in Aus.
is it 5/6 port? i cant count it
Yes
Universal motor?
Not sure to be honest. There’s not much way of me being able to tell as it’s very hard to access/remove and little to no information printed on the rating plate.
Bro Lit Build A Castle Castings Lmao
Bruh i want one
Sounds like a CS8
It sounds like 3t22
looks like a hatless aca sentry 95
well that's essentially because it is
what does ss6 stand for?
don't know I'm afraid
@@al66class59 It could stand for small siren
@@CycloneJoey518 its quite large tbh - 11kg and about a foot tall. though yes it could. idk the age of this, and obviously they're ridiculously rare, so i can't find any manuals/sales booklets for it.
@@al66class59 i think aca used the same design of this siren and called it the sentry 95
@@CycloneJoey518 read the description ;)
how big is that
Around a foot tall, probably just over. Much bigger than you'd expect for sure!
Very old siren for sure
zamn 🥵
6/7 Port?
5/6
Salve la vendi?
Salve- non è in vendita, mi dispiace.
How is it now?
Sorry, only just picked this up! It's still in bits - I had hoped to be able to paint it myself but it's got very fine tolerances with regards to gaps are between the base and rotor/rotor and brass stator etc, and hand-painted layers of paint are too thick, causing friction. Looking like it may need professional respraying at this stage.
Mechanically sound, it worked fine when I got it and didn't need much doing. Will be getting a longer cable and ideally a cable gland to improve safety with the junction box, however.
@@al66class59 nice! Whatever you do, NEVER throw this away.
@@SylvesterTheSupernatural16 Would literally never even consider it. This is, to my knowledge, the most complete and best-condition example of this type of siren anywhere in the northern hemisphere... I don't think I could even bring myself to consider selling it let alone throwing it away
@@al66class59 awesome! Where is this particular ss6 right now?
@@SylvesterTheSupernatural16 about three feet from where it was in this video, in my house's old garage- albeit in five bits now (rotor, stator, base, junction box cover and said cover's insulating sleeve)

more like model 2t

Maybe got too many projects on the go though as I seem unable to find time to finish this 😂

Naaaaaaaaaaaaaw
It IS a sentry 95
it is NOT a Sentry 95 but it's the closest we're going to get
Sentry 95 is made by klaxon.
And rebadged under license by ACA. Although no Sentry 95 has ever been found, we assume they're the same with the addition of a shroud for the US version.
@@al66class59 oof, I thought it was made by just klaxon signals.
@@EOWS408YT Yeah, the Sentry 95 was a Klaxon product even if it said ACA on it. It was more a US sales licensing than anything
Sound like a f16
That look just like a sentry 95
This was the basis for the Sentry 95 design.
@@al66class59 I heard allegedly the klaxon SS6 and sentry 95 are cousins
@@VonnaWasser They are essentially the same siren, just rebadged
So that a nft version of a sentry 95
Sentry 95 is a copy of this, not the other way around. The ss6 was made first.
