I visited Switzerland recently and saw plenty of these sirens heard here in this video. These are Kockum Sonics KTG series sirens. KTG sirens either have 9, 10, or 11 horns. They are pneumatic alarms designed to imitate the wailing of sirens. If you look them up here on youtube you will see what they look and sound like up close. I think Kockum created these because they have no moving parts exposed to the elements, unlike traditional sirens that have spinning parts out in the open.
Mostly in Germany a check is done with the signals "All Clear, Warning of Population, All Clear", e.g. like the tests in Cologne, Aachen and Bonn. Other Citys test only "Warning of Population" like Wiesbaden or Darmstadt. Some regions test sirens with the Signal "Fire Alert". Most used types of Sirens in Germany are called E57 (Motorsirens), but there are also pneumatics like the HLS 273 oder electronics like ECN 1800 or SiBT 250. Sometimes you can find older sirentypeslike VS56 oder L141
Most German sirens use motors and sound like sirens anywhere else. The Swiss sirens heard here are actually air horn arrays from Kockums Sonics (made in Sweden) that use several horns to simulate the rising and falling of a regular siren.
Thanks a lot for your expert comment, now I know! We don't want to get to close into the path who started total warfare anyway, vell, ze Germans were first with "to coventry" a city, right?
Honestly, English sirens have the most musical sound of all. They are motorised like German sirens but sound two notes instead of one. I'm sure, however, that the people of Coventry did not like to hear them.
It sounds like a train wreck X/

Disorienting and chaotic, should be directed in high-decibel concentration at Somali pirates.

Thank you ridemaster, a true expert you are!
If only my other vids would get that much attention as this little done-in-2-minutes-clip. On "bye-bye-Brighton" alone I´ve worked days!
