Sirenensignal "Katastrophenalarm" | Hörmann HLS F71 | Probealarm 1970 |

[@F71Andrixx]

The former siren signal "catastrophe alarm" with the original sound of an HLS F71 - this has never been heard before! But next Saturday, October 22nd, 2022 at 2 p.m., the time has come: I present to you the 21st part of my series #TimeTravel, which is something very special in several ways. For the video, the former “catastrophe alarm” siren signal was authentically recreated based on an original sample from an HLS F71. Many thanks to @FinSirens for providing his original recording. The disaster alarm was a siren signal in the Federal Republic of Germany during the Cold War, which was intended to warn the population in times of peace, for example in the event of natural disasters or chemical accidents. It was de facto a series of signals "fire alarm" (one minute continuous tone, interrupted twice) and "all clear" (one minute continuous tone). However, due to the risk of confusion with the signals just mentioned, the disaster alarm was abolished in the 1970s and replaced by the “population warning” signal (a one-minute, rising and falling howling tone). This was acoustically identical to the already known "air alarm" signal, but was called something different in peacetime. The siren is an example from the first generation of Hörmann's pneumatic high-performance sirens (type: HLS 168 / better known as F71), built in 1968. For detailed information about this type of siren, I refer you to the hochleistungssirene.de website (direct link: www.hochleistungssirene.de/ty... ). ++++++++++++++++++++ 🔊 Important information: The #TimeTravel series is a ❗fictional❗ project. ++++++++++++++++++++ Video chapter: 0:00 - Intro 0:14 - Introduction 0:35 - Test alarm 3:11 - Outro

Wie immer sehr stark gemacht. Es kommt wirklich sehr realistisch rüber!!

[@Rheinlandsirene]

Freut mich, danke!

[@CycloneJoey518]

Pretty good quality recording for 1970

[@betterunderfire]

the sample isn't from 1970.

[@thebuzcolasirenen3752]

Wird dann das Projekt f71 Feueralarm auf 22 verschoben?

[@Rheinlandsirene]

Nein, der Feueralarm ist identisch mit der ersten Hälfte des Katastrophenalarms.

[@TheSecurityFreak]

Welch schöner kratzender Ton! Gut gemacht 😁🥰😁

[@Rheinlandsirene]

Danke! Ja, die klingt schon sehr böse! 😈

[@thebuzcolasirenen3752]

Bin gespannt

[@FinSirens]

Very nice! 👍👍

[@Rheinlandsirene]

Thank you! Without your permission this would not have been possible!

[@Dnsbbv]

0:35 - I don't get it, what is that metallic-like whirring-like sound these pneumatic sirens make when they sound off (if you listen carefully you can hear it).

[@Rheinlandsirene]

That's the magnetic air valve.

[@Dnsbbv]

@@Rheinlandsirene No, I actually mean the whirring-like distortion sound layered within the general pneumatic siren sound.

[@Rheinlandsirene]

@@Dnsbbv Ah, got you! Well, I can't exactly tell you, but all pneumatic sirens of the first generation had this kind of distorted sound (more or less). In this case it is quite extreme indeed. It must be a mechanical artefact related to the chopper. Even some mechanic sirens have similar sound characteristics, e.g. this one: kzbin.info/www/bejne/jqqQdWuejZqNgMk

[@Dnsbbv]

@@Rheinlandsirene Okay, thanks 👍🏻

[@migstechnikbude]

Bei dem Druck fliegen doch die Dachschindeln weg und wie viele Fenster sind dabei zu bruch gegangen? Schauriger Sound aber besser so als gar keine Warnung!

[@thebuzcolasirenen3752]

Sehr schönes Video

[@agrarservicetb9800]

Gutes Video ! 👍

[@Rheinlandsirene]

Danke 👍

[@agrarservicetb9800]

@@Rheinlandsirene Bitte ! 👍

[@giborisrael4229]

Is that a real recording?

[@Rheinlandsirene]

The sample that I used is real but it is not an original recording from 1970.

[@GilZu]

Sounds bit diffrenet from the F71 i know

[@GilZu]

Best siren

[@grandyoel.k]

This siren sound just beautiful and terrifying, we had those siren in israel till 2012 and for real i miss those high preformence F71 sirens, now we have only electronic sirens and they are damn weak and lame compare to those!

[@BlueThunderboltsiren]

Hallo! ☺️

[@coolcrafter3d690]

Sehr geiles Video, feiere dein Projekt Zeitreisen ich finde sehr interessant wie früher die Warntechnik funktioniert hat. Könntest du bitte mal einen original Warntag mit allen Signalen von Damals nachstellen so wie er im Kalten Krieg wirklich abgelaufen ist? Ich würde mich auch sehr über weitere Dokumentationen (so wie der Rheinlandsirene Warn Tag) von dir freuen Lange lebe die Hochleistungssirene 😎👍😀

[@Rheinlandsirene]

Danke schön! Das habe ich tatsächlich schon mal mit dem ersten bundesweiten Probealarm von 1965 gemacht. Gut möglich, dass ich in Zukunft aber nochmal ein vergleichbares Projekt in Angriff nehmen werde.

[@betterunderfire]

Das Signal war wirklich nicht sehr durchdacht oder? Als Mitglied der Feuerwehr fahre ich erstmal los, nur um dann eventuell festzustellen, dass es sich gar nicht um das Signal Feueralarm handelt. :D

[@Rheinlandsirene]

Ja, muss man schon so sagen. Da ist es auch nicht verwunderlich, dass man das Signal schon so früh wieder abgeschafft hat.
