Waking Up A Hörmann HLS-273 After 15 Years

[DJ2226]

Neat video from Germany. This siren has been inactive since 2007, and the city decided to revive it after all these years. It sounds a bit rough at first, but it gets itself together after a few cycles of the warning tone. It's still running with its original diesel engine-driven generator and air compressor, which is interesting as most of these sirens have since been converted to HLS-373s by the cities with either an electric motor being installed to drive the compressor or a separate compressor being added to the bunker and plummed into the lines feeding the tank. Seeing another HLS become active is nice, given how rare these unique sirens are.

Sounds unique, and the controls seem fairly simple.
