Air raid
The air raid alarm was an alarm signal in World War II that was given by means of sirens . The term was changed in the 1960s as the threat could now come from missiles and no longer exclusively from aircraft.
history
The addressees were not only soldiers, but above all the civilian population. The air raid became known and significant during the Second World War during the bombing of German and English cities.
In the mid-1950s, civil defense was reorganized in West Germany , and the expansion of a comprehensive siren network began. The sirens could be triggered by ten warning offices spread across Germany . The air raid alarm from World War II became an aerial alarm , which until the beginning of the 1990s should have warned the population of air raids with a one-minute howling sound in the event of a defense. In the mid-1970s, it also replaced the old disaster alarm (consisting of three twelve-second continuous beeps with a twelve-second pause each, followed by one-minute continuous tone) and was thus used for disaster protection during peacetime .
Alarm tones
First it was given as a two-minute howling sound in the early years of the Second World War over so-called air raid sirens; From the middle of the Second World War it was then shortened to one minute by the new air protection regulations. The so-called flyer warning was then used beforehand: three continuous beeps of twelve seconds each.
Towards the end of the war, the "acute air hazard" signal was reintroduced in Germany if there was an immediate threat to the alarmed air raid shelter. " It consists of a short burst of alarm, consisting of two siren howling periods with a total duration of eight seconds ...... The end of the" acute air hazard "is indicated by the" advance all-clear "signal (high-pitched continuous tone repeated three times) ... ..The final all-clear is given by the previous all-clear signal (one minute long, high-pitched continuous tone). "
