BIG NEWS!

The Carlise, Cumbria Klaxon is ACTIVE!
I was talking to a friend who works near the siren, and he said that he used to hear it sound once every six months.
However, since the Ukraine War began it has started sounding once every two months!
I will try to gather more information on this, but this is what I know so far. This is very exciting!

I hope this siren inspires the government to install outdoor warning sirens. The phone alert system was kind of a bust. In fact, Estonia is installing sirens right now!

Just remembered I have this account, so I've got some things to add...

At least two electronic sirens at BOC Gases in Immingham - think they are Klaxon ES but can't be sure, I don't know enough about these electronic things...
53.606310, -0.158250 - six-horned bi-directional. Not visible on Street View
53.605731, -0.157643 - two-horned bi-directional. Is visible on Street View

Am having a look through my other photos from that day to see what else I can spot (there was a railtour round some lesser-used rail lines in the Immingham area, which I was on) but I suspect the others in the area are now mapped.

Update on a London siren. The whatever it is on the roof of Vanguard Self Storage is still there as of May 2022. The Hawker Hunter jet fighter that was on the roof was moved inside after being taken down, and I wanted to see if the siren was still up. To my surprise, it is! See the upper right section of this image:

Can confirm this is a Secomak GP8; I went to this location a number of years ago (along with Lewisham and Queensway for their Carters) and it's got Secomak lettered end plates on.

Looks to be an earlier one, with the junction box being of that angled-seal design often seen on Cold War-era Carters, but still having the classic Secomak base. Missing its junction box cover, however, so not clear if it would now work!

I think it's visible from Streetview after fooling around on the roads. Clearest shot manageable:

Well spotted - not sure how I missed that. I suspect it's just those two on site, looking at my photos from the day. Will stick a photo of each in a reply...

Removed (blue?) Klaxon CS8.

Looks like a Castle Castings. Next to a mini air raid shelter at the Devil's Porridge Museum.

Went for the fireless steam locomotive at one end of the building, stayed for the siren at the other!

Edited to add:
A couple of oversights...
51.466155, 0.269190 - it transpires there's a second GP8 on site at Navigator in Essex. This one is round the back of the site.

I suspect it's just those two on site, looking at my photos from the day.

53.606391, -0.158066 - it also transpires I am completely and utterly blind, and there is quite clearly a GP8 next to the larger electronic siren.

I am now sure that well and truly is the lot for BOC Stallingborough!

Wow, that is pretty cool! We’ve driven past that museum a couple of times, saying ‘we should visit that place some day’. Definitely going at some point to see this siren!
Although it does have some similar features to a Castle Castings siren, due to the overall look of the siren I’d say that it is a Secomak of some kind (I can’t remember the exact model). I say this because the base of the siren is not curved like a Castle Castings, but rather more angular, like a Secomak. The wire junction boxes also seem to be situated at an angle to each other, similarly to a Secomak. The only thing that may be confusing is the lack of the word ‘Secomak’ on the heater, however if it is a Secomak I’d probably go with the theory that they had to replace the heater and didn’t bother adding the wording onto the new component.

I’m not too educated on Secomak sirens so I may be slightly incorrect, but hopefully this helps.

I'm 99% sure it's not a Secomak as it doesn't have chamfered (angled) stator holes, which Secomaks almost universally do. This narrows it down to CC or Carter, as it quite clearly isn't a Gent

I say this because the base of the siren is not curved like a Castle Castings, but rather more angular, like a Secomak. The wire junction boxes also seem to be situated at an angle to each other, similarly to a Secomak.

Earlier Castles also had squared bases. Could be a Carter, but pretty sure they always had centralised motor junction boxes, which this one doesn't. That said, there aren't many Carters left to use as a reference, so don't quote me on that.

The thing that makes me doubt myself is that it doesn't have the stereotypical "giant" rotor bolts that CCs often do, instead having the flatter bolts as you'd see on Carters. Heater junction boxes are only angled/pointing upwards because the museum/whoever restored the siren refitted them at a funky angle!

FYI, the Secomak-lettered "heaters" you refer to were just end plates - to protect the rotor sides - and didn't have heating capabilities. Heaters typically didn't have letters on, no matter what they were attached to, as they were (to my knowledge) a standardised component that could fit numerous models of siren.

So it's either a Carter with a very late-production motor, or a CC with different rotor bolts. I could go and forensically analyse the rotor vanes for further clues, but a lack of reference photos may hamper that!

Ah, thanks for the information. I’m not too familiar with British sirens because as you said, there isn’t too much documentation on them. This actually cleared up a lot of incorrect information in my head, so thanks for that
