Made a lot of research today, and found many different things about sirens in Lviv.
First of all - siren system they use
1. С-40/С-28 (almost impossible to identify which one it is, because different factories make different shroudings for them)
they all mounted on roof's so this is the only one i found: 49.842102051975196, 24.031324568511767
2. Digitex sirens
49.790770044541404, 24.057251208746724 (no street view because siren was installed after 2015)
3. Some mysterious sirens called "BGO-1200", "BOU-200" and "BGO-900", on Ukrainian its "БГО-1200", "БОУ-200" and "БГО-900". "BGO" means "Loudspeaker Unit" and "BOU" means "Universal Block of Loudspeakers". The BGO-1200 is seen in reportage for BBC news (https://www.bbc.com/news/av/world-europe-61204407
) on 0:33 timestamp. These are also being produced on different factorys. One of them is on 49.858067319983924, 24.022309669658046, and i have photo of it:
4. (last one i could find) some even more mysterious siren that looks like UFO
it was shown in news reportage about siren so im pretty sure its a siren.
Sadly there isn't any info about sirens in ukraine, so i dont have many info about them. Also most of the sirens was installed in ~2019-2022 so you cant see them on google maps, and it makes searching process even more harder.
