Method and device for the early detectiion 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 fighting of fires in the interiors and exteriors of homes or buildings 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 and alarm devices, and in which individual sensors simultaneously detect the direct and indirect combustion characteristics (conditions caused by fire) in the dwelling and residence places, 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, characterized in that, based upon detected changes in time and/or space of the fire-caused conditions, the domestic discharge, supply and removal processes are controlled by the following steps:
- a) separate or simultaneous monitoring and controlling the changes in time and/or space by a smoke detection, temperature detection, gas detection, scent detection or image detection;
b) determining the deviation from a 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) interactive control of the central domestic control unit with the check control and regulating unit and triggering an alarm by the central domestic control unit;
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.
