To ensure the safety of lives and property of everyone, the family of automatic fire alarm system design to become the most important civil building design. These papers discuss the automatic fire alarm system requirements and development status at home and abroad are analyzed and organize the structure and characteristics of the system are described in detail. Based on the analysis form the basis of the whole system and fire alarm reference to the relevant norms of the specific content of the system design were discussed in detail. Components in the system design, modular feature of the system by using the microcontroller and digital electronics, in accordance with the design of different functional modules, there are fire detector module, the alarm controller module, display module, keyboard interface module, the printer interface
