A video of the most recent test of Buncefield Oil Terminal's Klaxon ES2(S) siren. This is my local siren and is one I've recorded before, but the siren's been replaced by a newer one since I last filmed it and it now sounds a bit different in hi-lo (I might even say better!)
I recorded it in March 2024, but it took me a lot longer to get round to editing it than I'd hoped...
