Heidemann Multi-sound gong Quarter

Heidemann Quarter (wired, wireless). The Merklang-Gong Quarter has been specifically designed for 2-wire operation. Particularly in older doorbell systems, there is the issue that only two wires are available for installation - one line from the transformer and one from the doorbell button. As a result, only electromechanical gongs can be connected, not electronic ones. In this installation, after pressing the button, there is no longer any power at the gong. The item shown here is specifically designed for this 2-wire installation in conjunction with a battery. The battery ensures that the melody is played after the doorbell button is pressed. However, the model can also be connected in the same way in an existing multi-wire installation. Both illuminated (only when connected to a doorbell transformer) and unilluminated doorbell buttons can be used.
