A bell automation system is a device, the aim of which is to maximize the automation of bell ringing and thus release from duty the person in charge of it. The modern way of life and forms of employment generally make it difficult for human bell-ringers to carry out the task as they did for centuries. In this thesis it is explained what can be expected of the bell automation system in the regions of Slovenia, and why it is desirable that it supports certain functionalities. Using as an example a basic variant of the bell automation system, the fundamental workings of such a device are demonstrated. For easier understanding of some design choices, the basic bell ringing customs in the Slovenian geographic space and the development of bell ringing automation throughout its history, are explained.
