Abstract: The subject of the research is electrical equipment, in particular split systems installed in residential buildings and apartment complexes for creating comfort temperature conditions. The results of the research confirmed the high fire hazard posed by these systems and the necessity of improvement in order to conform to GOST 12.1.004 fire safety specification. The research shows that this objective could be achieved by installing thermionic protection modules for internal and external blocks. The methodology of "safety intellectualization” was used in the course of the research and improvement of internal and external blocks of the split-system. The model is developed on the basis of technology of "safety intellectualization". It includes includes protection of the device against ignition by means of modules of thermionic protection and also installation of the independent smoke fire announcer with the GSM modem as means of identifying the dangerous factors of fire hazards and signaling the fire department.
