🚨 Hänsch Sondersignalverstärker Typ 620 | #Sondersignalanlage mit TFV 620

Hello everyone, we're sticking with the automotive theme, but today we're looking at something that, while interesting, might not be for everyone: the technology of an emergency warning system. The #Hänsch #TFV620 is a few years old, but still frequently used by fire departments, ambulances, and police. In this case, it's about an amplifier that I received as defective, but unfortunately, the system didn't work with a new one either. The problem lay elsewhere. With the help of the wiring diagram or this video, the fault could have been found quickly. However, "amplifier" is actually a misnomer, as the device doesn't amplify any existing signal; it also generates the sound. 00:00 Introduction 00:55 What do we need? 02:48 The AMP connector 03:14 The settings 04:42 The wiring diagram 11:40 Don't use more power than necessary 12:24 The test setup (it gets louder from here on) 15:19 The credits I assume no liability for property damage and/or personal injury resulting from these instructions or their implementation. No warranty and no liability for damages of any kind resulting from these instructions!
