In accordance to the functional-structural approach "... the structure is defined by the function...", ie structure of a computerized fire alarm system is determined by the functions of the system. For the development of the computerized fire alarm systems structures the functions classification is the basis. The target function, primary functions and secondary functions distinguished. Divide into the proposed types is conventionally. Any structural element that implements a function can be regarded as a separate system. Therefore in some cases an secondary function of the system can be considered as the primary function, and the primary function as a target function. The questions of systematization of computerized fire alarm systems functions are considered. The hierarchy of functions categories of computerized fire alarm systems is proposed. The classification of the computerized fire alarm system functions in accordance to proposed hierarchy is given. The functions of the 1st and 2nd levels of the proposed classification are considered. The proposed computerized fire alarm systems functions classification can be used to perform morphological analysis, development of technical specifications and development of structure computerized fire alarm system.
