A hand-operated siren is a siren that is powered by a hand crank. These sirens were once used to warn of approaching storms or other emergencies when there is no external power source is available. Hand-operated sirens are not as loud as electric or gas-powered sirens, but they can still be quite loud. Some hand-operated sirens can be quite large, while others are small enough to carry in your hands
