Operation: You turn the crank handle by hand to spin an internal mechanism that creates a high-decibel air-raid or fire alert tone.
Design: It features a durable, hammered-gray metal housing with red internal sound slots and a collapsible stand frame with a carrying handle.
Use: It works best for remote camps, outdoor events, factory sites, or emergency civil defense warnings where power is absent.
