The final paper lists the laws that link fire protection and building construction. Parts that closely link the two areas are extracted from individual laws. By explaining the causes of fire and how to prevent its spread, an example of a fire alarm system in a shop and a coffee bar is given at the end as an example of the previously mentioned theory. The mentioned laws are found in the second chapter, where the topic they deal with and what they are divided into are stated. The most important parts related to the topic are commented on or quoted. The second chapter lists some of the possible causes of electrical fires that are related to device malfunction or user negligence. One way in which temperature changes in equipment can be monitored in larger plants is by using IR cameras, the use and application of which are explained in the fourth chapter. The fifth chapter is closely related to firefighting and thus includes measures of active and passive fire protection. The need for protection is explained as well as the method of its implementation. The sixth chapter shows the power of fire that destroys everything in its path and takes human lives with it. Examples are shown here where a harmless situation turns into a disaster. In order to cover the entire topic of the final thesis, from standards to the implementation of fire protection, the seventh chapter presents an example of a fire alarm system in a store.
