Method and device for the early detection of fire and for fighting fire indoors and outdoors, especially in living areas, of homes and buildings
First Claim
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.

Abstract
The invention relates to a method and device for the early detection of fire and for fighting fire indoors and outdoors, especially in living areas, of homes and buildings. According to the invention, a central freely programmable domestic control block comprising an intelligent bus system, sensors, and actuators controls, regulates and monitors the domestic technical system and, at the same time, sensors detect the direct and indirect fire characteristics, which are monitored by a separate check, control and regulating block that activates an extinguishing agent supply system when a set value has been exceeded. The aim of the invention is to improve a method and device of the aforementioned type such that the extinguishing agent is variably and selectively discharged with a high degree of efficacy by the provision of a system which can be modularly integrated in the security design of a building. The extinguishing agent is variably and selectively discharged according to the origin and progression of the fire while simultaneously minimizing the water consumption, decreasing the damage caused by water in the case of a fire, and increasing the economic efficiency. To this end, the invention provides that the check, control and regulating block interactively communicates with the control block of the domestic technical system, and that an extinguishing agent supply system is actuated which integrates all available extinguishing agent sources of a house and initiates the discharge of extinguishing agent with a variable quantity and distribution according to the origin and progression of the fire.
