These are all the locations I've found so far (all in one evening) so I've still got a bit of searching to do for sirens in the Lincolnshire system as there is supposedly 46 sirens. I went for the
most obvious places to look, that being fire and police stations round Lincolnshire. I will do some more digging into this soon and report back when i find anything
