Heidemann Multi-sound gong Quarter

Heidemann Quarter (Wired, Wireless). The Merklang-Gong Quarter has been specifically designed for 2-wire operation. This is particularly relevant for older doorbell systems, where only two wires are available for installation - one from the transformer and one from the doorbell button. As a result, only electromechanical chimes can be connected, not electronic ones. In this setup, there is no power at the chime after the button is pressed. The product shown here is specifically designed for this 2-wire installation in conjunction with a battery. The battery ensures that the melody plays after the doorbell button is pressed. However, the model can also be connected in the same way to an existing multi-wire installation. Both illuminated (only when connected to a doorbell transformer) and non-illuminated doorbell buttons can be used.
