This graduate thesis analyses the application of the fire alarm system on ships in order to increase the safety of the ship and people. A fire on the ship is considered to be one of the most challenging and dangerous situations therefore early detection can play a crucial role in extinguishing and preventing its spread. A quality fire alarm and extinguishing system can be crucial in rescuing people and ships. The fire alarm system except announcing the fire quickly and giving the position of the fire must also take certain actions in extinguishing the fire, such as closing the fire door, activating the fire extinguishing system, etc. The development of new technologies leads to the significant development of fire alarm systems with a higher degree of reliability, availability and security. Therefore, the application of such systems on ships is expected to increase in the future. This graduate thesis describes the causes of fire on ships and dangers that lead to fire, all components of fire alarm system starting from the fire control panel, fire detectors to the executive elements, and lists and explains new systems whose application would improve the safety of people and the ship.
