That's an excellent question, I know that KMEurop was taken over by Finsécur (who makes fire alarm equipment like panels and sounders) in 2006 and subsequently renamed KM-Sécur.. But that stops there, I don't think they're related to CEN in any shape or form.Dorianelevator wrote: ↑Fri Mar 08, 2024 4:45 pmnope, just one more thing, that is, whats the diffrence betwheen CEN and KMEurop/KM-Secur ?
I'm thinking that R3Ps and CEN sirens are only related in shape, like the government giving siren blueprints to the companies and telling "yeah so we need you to build a siren following those schematics as a baseline, they must have 8 ports and so on bla bla bla" which could explain why CICCA, CEN and KMEurop sirens look identical with some variance.
Alternatively, once CICCA went belly-up, the tooling got bought out by CEN and subsequently passed onto KMEurop.. Although there's a problem with my theory, my friend's Cicca siren looked just like a Demay R3P just a bit shorter and with a "+" armature in the base (which isn't obvious if you leave the mesh screen on).
So I think that Demay might have taken over Cicca's siren business and refined the sirens over the time. KMEurope probably also succeeded to CEN, but again, that's total speculation.
There's not much info known about PTR and CEN, if we knew more, we could probably piece a timeline..
PTR probably adhered to the sound specifications but didn't follow the baseline schematics.
Of course this is raw insomnia-fueled speculation so maybe I'm completely wrong or right, take this with some "pincettes"
I know that my friend's siren was very similar to a R3P, the base was slightly taller than a CEN and it had the same motor as the Demay R3P though running a bit faster.
Oh and, I remember seeing a very old postal card with a picture of my hometown's city hall, and it shows that the city hall had a different siren on the roof, IF I can find a scan of that picture, I'll try and upload it here so you can see for yourself.
I haven't identified the old siren but it looks like the old Verneuil and Laigneville siren, (short horns with a cone hat), I've only seen this type in Oise.. MAYBE this was a early Chollet-Cicca like you found on Leboncoin, but there's no way to tell unfortunately.
