Is that a thing? At least in this part of the EU, they never ever sound unless it’s a genuine emergency or the monthly test. I’m pretty sure the only reason they would go off is for a tsunami because they don’t even go off for tornados.
I think in the US you can set it to a lower-than-highest level, but in Canada, they send the kid-in-a-custody-dispute ones at the nuclear incident level (which was also sent out by mistake once).
Nothing sadder/funnier than seeing politicians defend their broken system as it increasingly did broken things.
