Are controlled by Eaton County Central Dispatch and are sounded based on written policy.
They're called OUTDOOR warning sirens for a reason. They are designed to let those who are outside know they need to seek immediate shelter inside. The sirens are not intended to be heard inside your house, in your vehicle, or in a business. They are NOT designed to wake you up.
You need to have other sources of warning (sign up for local alerts, NOAA Weather Radio, news apps, television) besides a siren.
If you are waiting for a siren to tell you to take shelter, you could be putting yourself in danger.
