1. A method for early detection of fires and for fighting of fires in an interiors or exterior of a building in which a central control unit with an intelligent bus system, sensors and actuators controls, regulates and monitors the lighting, heating, air conditioning, windows, jalousies, intrusion protection alarm devices, and in which individual sensors simultaneously detect direct and indirect combustion characteristics as conditions caused by fire in the building, which are monitored by a separate check, control and regulating unit which, upon the overstepping of a setpoint value, activates an extinguishing supply system to release an extinguishing agent, said method comprising the steps of:

  • a) monitoring and controlling said extinguishing supply system in response to changes in time or space of said conditions caused by fire by a smoke detection, temperature detection, gas detection, scent detection or image detection;

    b) determining the deviation from said setpoint value with the check, control and regulating unit;

    c) interrogating with at least one additional sensor through the check, control and regulating unit for distinction of a permissible controlled flame from an impermissible uncontrolled flame to the extent the deviation determined in step b) exceeds the setpoint value;

    d) interactively controlling of the central control unit with the check, control and regulating unit and triggering an alarm by the central control unit; and

    e) simultaneously and in parallel with step d) controlling the extinguishing agent supply system as a function of the change in conditions caused by the fire for variably releasing the extinguishing agent in terms of quantity and distribution until, according to step b) there is no longer a deviation detected from the setpoint value.
