The final paper describes the fire alarm system, its basic characteristics, working principle, description of basic elements and application on the actual building, Hotel Dalmacija, which will describe the installation, configuration, testing and maintenance of the system. The task of the fire alarm system is to warn of the occurrence of fire or smoke as soon as possible, and thus to enable a timely response in order to protect, above all, human lives and material goods. It is also very important to avoid false alarms that can be caused by a malfunction of the installed system or poor management of system elements. In order for the fire alarm system to correctly and timely detect fire, it is necessary that the system is properly designed, installed and regularly serviced by authorized service technicians according to the latest standards and norms. In the Republic of Croatia, there is a non-profit organization called the Croatian Standards Institute, which develops and publishes Croatian standards. Each fire alarm system consists of several basic elements such as a fire alarm control panel, automatic fire detectors, audible and visual fire indicators, manual fire detectors and input / output modules. In modern, analog-addressable fire alarm systems, all devices are connected to the control panel in a loop and system has two central processing units for double redundancy, to ensure the correctness of the system even in case of error or malfunction. The aim of the final paper is to describe in detail the fire alarm system, its characteristics and the importance of such a system, on the example of Hotel Dalmacija, that in case of fire, its consequences can be minimized with the help of fire alarm system and other fire protection measures such as evacuation routes, hydrants, fire doors, smoke extraction system, sprinklers and fire extinguishers.
