Only in areas that have them. Many places don't. The sirens will only go off if the tornado is detected in time. Usually they are, but not always.

The sirens may have gone off to alert people of an emergency or danger, such as severe weather, a fire, a hazardous material spill, or a missile threat. It is important to follow any instructions provided during a siren warning to stay safe.
Sirens are typically used to warn of severe weather events, such as tornadoes or thunderstorms. So when the sirens go off, it could indicate a sudden change in weather due to an imminent threat. The purpose is to alert people to take immediate protective action.
