Thanks Mariano!
Sadly - I was hoppy wrongly, this siren is basically same as multi-sound siren Philio PSE02 / D-link DCH-Z510. It needs custom driver, did see the groovy version here even (DLINK DCH-Z510 Siren - #4 by nimrooz), but discontinued by the author.
Nevertheless - it is working as a z-wave switch and I`m able to configure it using your z-wave device config driver. Will see what to do later on
