Think it's some sort of warning noise or something like that?
It is indeed a driver warning sound. It sounds when any of the warning lights illuminate on the dash. This could be for anything as simple as a filter change required or low water etc.
The difference between the stopping bell and the warning version is purely that the stopping one rings two tones ( bit like Avon calling adverts used to be) and the warning one rings one tone only. Drivers get used to it after a while and then not stop if it rings once only.
The real problem is that the tone used for both is identical.
