Fires in agricultural buildings pose a significant risk to animals, people, and property. Due to the presence of flammable materials, such as hay, bedding, and wooden structures, fires can spread quickly, making early detection crucial. The main aim of this bachelor’s thesis was to investigate different fire detection and alarm systems and determine which system would work effectively in different types of farm buildings, namely cattle, pigs, hens and broilers, horses and small livestock barns, as well as hay storage facilities. Based on a literature review, we examined different types of detectors, such as smoke, heat, and flame detectors, and evaluated their advantages and disadvantages. In agricultural buildings, we focused on factors such as temperature, humidity, dust, air movement, housing system and the size of the room because they can affect detector performance. Analysis of collected data showed that the demanding conditions in barns, especially in areas where animals are housed, allow for the reliable operation of only certain detectors. The most suitable option is the aspirating smoke detector because most factors in barns have minimal effect on its performance. The multisensor detector is also relatively suitable because the two sensors working simultaneously in one device help to reduce false alarms. Heat detectors are unsuitable because they detect fires too late. Flame, beam detectors, and video-based detection systems are only suitable for large, open spaces where their effectiveness is limited by the dust in the environment. In barn spaces intended for human occupancy, such as offices or changing rooms, optical smoke detectors and multisensor detectors are most suitable. Any fire detection and alarm system should also include a manual call point.
