Bloody hell! That alert tone sounds almost like our emergency signal that they broadcast.
As for the sirens, they could be speaker arrays like Taiwan has (as seen in the Taiwan sirens thread). I can't find anything definitive on the internet.
The tone quality does sound like a H?rmann, and Chile has always had close ties with Germany, so you're probably right. It sure is an annoying sound, though.
