I think it is very loud. Think it could be heard over 200 yards.

Can this be heard by upstairs neighbours if plut against the ceiling

No idea. Suppose it depends on how thin/thick the ceiling/floor is? Also putting it against a surface may muffle the sound.

Is the siren volume adjustable

Yes. Just slide the 'button' along from (-) to (+). Quite a good range, from very quiet to loud as a police siren.
