Abstract: In this article the transformations model the split-systems-firefighters of the announcer is presented to the automated installation fire and explosion protection of the apartment / an individual house. The offered approach uses aspiration properties a Split system (room air course where the internal block is installed) that allows to carry out early detection of dangerous factors of the fire (smoke) and explosion (leak of household gas), at installation in the internal block of the smoke fire announcer with the GSM module and also the sensor which finds leak of household gas in the individual house. The methodology of "transformation" consists in installation in the internal Split system block of a thermomagnetic separator of air (TMSA), and on a gas pipe of the apartment - the gas meter with the built-in sensor and the electromagnetic valve which blocks supply of gas on a signal of the built-in sensor and also at operation of the gas sensor in the internal block a split system. The novelty will be that at detection of dangerous factors of the fire and explosion in the apartment or in an individual house, the notification of the relevant services and TMSA which deletes oxygen from premises on the street joins, leaving nitrogen, than suppression of fire and dilution of the explosive environment is provided.
