Mechanical chime

One mechanical chime is the part of a doorbell that generates the beep mechanically.

This type of chime is still the most common in Germany. Mechanical or electromechanical doorbells are very common in households due to their reliability and the beautiful sound of chime steel. Usually as 2-tone or ringing mechanism.

On most models, the sound is produced with a tone bar. This technique makes it possible to make a mechanical chime very flat.

The sound of a mechanical chime is always very clear and full when signaling.

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 bells is usually provided by a bell transformer (7). Radio bells are usually powered by batteries. Only with 230V radio bells (4) the receiver is operated via a socket with earthing contact.

Bell pushbuttons (5) are mounted outside in front of the door. Stainless steel 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.

TIPP:

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 chime is additionally connected to a bell transformer.
