There are different types of chimes. A distinction is made between sound generation and the type of signal transmission. There are electromechanical chimes (1) and electronic chimes (2). With electromechanical chimes, the sound is produced by a tone iron, with electronic chimes the sound is produced by a tone generator. When it comes to signal transmission, a distinction is made between wired chimes (1+2) and wireless chimes (3+4). The power supply for wired chimes is usually provided by a bell transformer (7). Radio bells are usually powered by batteries. Only with 230V radio chimes (4) the receiver is operated via a socket with earthing contact.

Bell buttons (5) are mounted outside in front of the door. Stainless steel bell pushbuttons are particularly weather-resistant. They are hardly affected by rain because stainless steel is rustproof.†For a visitor or parcel service, illuminated buttons (6) are an orientation aid on the front door, especially in the dark season.

With bell transformers (7) the voltage or power supply of a bell system is carried out. Bell transformers require an input voltage of 230V~ and usually supply an output voltage of 8 V~. Depending on the current consumption of the connected bell, a bell transformer with 1 A or 2 A is required.


If an electronic chime or a melody chime is used, the specified batteries must always be inserted. A voltage supply with batteries is also necessary if the gong is additionally connected to a bell transformer.
