It's probably an old air raid siren left over from the second world war and subsequently the cold war.
Most where removed after the stand down of the ROC (Royal Observer Corp) and the UKWMO (UK Weapons Monitoring Organisation) after the collapse of the Berlin Wall and the end of the cold war.
Some have been left in place as a flood defence warning system near rivers at risk of flooding or in coastal area's.
I hope this helps

It is a two tone siren that raises and falls in pitch, but they do not have the effects caused by space, there are some Doppler effects from sirens further away, and the whole effect is more mournful than you can imagine, stood in the streets very late at night with this siren wailing from our local town hall, the echos from the town and village halls in surrounding areas..... and other small groups of people stood in silence apart from the wailing of the sirens.

However, not all locations had electricity, so the search was on to find a non-electric siren. Chrysler corporation, was a big war time supplier created what it called the "victory siren".
