Mil-Tec - Air raid siren

The hand-operated air raid siren is an energy-independent alarm and signaling device that was previously used for air raid or fire alarms. Maximum volume is achieved with minimal effort. By gently turning the crank, a howling sound is generated even at low speeds, which increases as the speed increases. When the lever is pressed (flaps open and supply additional air), a deafening sound develops that can be heard from far away.
Suitable areas of application are public institutions such as schools, fire brigades, THW, construction sites, etc. Also suitable for carnival events, as a gag at club celebrations, in football stadiums, etc.
