Which parts of Austria and Germany are that? In Germany the air raid sirens are part of the emergency broadcast system and outside natural disasters only heard during tests. These tests happen on a schedule and when done at a federal level )(i.e. when the cellular emergency system is also tested rather than just the sirens) you'll hear about them on the news in advance. I'm not aware of them being used to summon the fire department and don't think that's very common outside maybe extremely rural areas. AFAIK volunteer fire departments use mobile phones.
