The hand-operated air raid siren is an energy-independent alarm and signaling device that was previously used during air raid or fire alarms. With minimal effort, maximum volume is achieved. By lightly turning the crank, a tone is produced even at low revolutions, which increases with higher speeds. By pressing the lever (which opens flaps and allows additional air in), a deafening sound develops that can be heard from afar. Suitable areas of application include public institutions such as schools, fire departments, THW, construction sites, etc. Also suitable for carnival events, as a gag at club parties, in football stadiums, etc. Aluminum pressure housing with foldable handle and hand crank Weight 1,200 g Siren diameter 115 mm Dimensions when folded approx. 125 x 125 x 130 mm. Sound pressure level (1m): 110dB (+/- 2 dB) Tone frequency dependent on speed 550 Hz (+/- 20 Hz). Delivery includes a canvas carrying bag.
