Nice! It does sound like that. Here is a very simalar siren company that someone I knew worked for! This is a Sentry 10V Sentry 10V Siren Test Strattanville, PA 4/8/23 (Skip to 0:48)
Oh yeah those, heh, I always thought they looked funny with the uneven horns..
Funny enough, there’s two Fedelcode model 5s known to exist in France, and there’s what’s suspected to be an heavily modified STH-10A near me, however it’s unconfirmed, I just know it’s in a small town called Cempuis.. One of my friends think it’s a CEN 8 port siren with square horns, but unless I go there in person to confirm we won’t know for sure.

Based on how those horned are angled with the rotor, you friend might be right. Look at the horn placement on the STH-10 vs. that siren.
I guess that’s settled, I found this other picture, and if you crop it a little bit…
There we go:
Comparing it to the NP3S I filmed in Lamorlaye:
Oh well, I’m a bit disappointed but at the same time, I’m glad to finally know what it is, it’s been bugging me since the past month.
Does that siren still work?
The Lamorlaye one sure does, it is tested every first Wednesday of the month at 12 o’clock. I recorded it at one point.
Unfortunately, I kind of messed up (forgot my tripod and my phone died) when recording 
so hopefully next month I’ll go back there and do a proper recording
Someone else also filmed it:
As for the Cempuis siren, I have little to no idea, but I don’t see why it wouldn’t, though if I were to guess, it’s probably sitting abandonned in place.
My city has an inactive sterling M-5 and recently got a Federal Signal 508 to replace the sterling. Also 1/2 a mile across town there’s a t-121 on the technical college.

That’s cool! They should hook the Sterling up to do a noon blast.

They don’t have any sirens where I live.
Here’s some photos from my old town’s sirens. All are functional, except for the alertor and P-15. They also recently got a T-135 to replace both. (First photo)

My county has a system of 29 Whelen Vortex R4’s all installed in 1998. But the EMA has recently submitted a FEMA grant to replace all 29 and add 2 more. I don’t know what sirens are going to replace the vortexes yet. Most of the vortexes are finbacks too. it’l suck to see them go.
Hopefully they get replaced with voice capable ones, otherwise I’d say it’s kind of a waste of money.
This is what I saw when driving
