Well, I hope the red button that launches the nuclear retaliation is secured a bit better...
But even the air raid alert is a serious thing. If the people think its a real alert it will cause widespread panic, with people possibly die from heart attacks, car accidents and whatever. That is quiet a different league than annoying people on a sunday morning. :)

But perhaps you should secure this tornado siren button better, like using a key switch or something instead of a simple button. Because, as a saying we have here goes, only people who dont work dont make mistakes. ;)
