Patent ID: 8496067

Claim:
A system having a device for protecting an inner space of an object against fire, comprising: a housing provided with at least one passage opening; an aerosol-forming extinguishing element which can be arranged in the housing and which includes: a container for holding extinguishing material which can be activated at a fixed activating temperature; at least one outlet opening which can be connected to the passage opening in the housing and along which the activated extinguishing material can be carried into the inner space of the object so as to extinguish the fire; an activating element for bringing at least part of the extinguishing material to the activation temperature; at least one detection unit for detecting at least one physical and/or chemical parameter representative of fire in the inner space, the at least one detection unit includes a temperature sensor and a smoke detector; a control unit coupled to the at least one detection unit and the activating element for causing thermal or electrical activation of the extinguishing element by the activating element when a preset activation value of the detected physical and/or chemical parameter is reached, and a power supply, wherein at least that the control unit is connected to the power supply and includes a programmable electronic circuit, in which the activation value of the physical quantity is stored and wherein the at least one detection unit, the control unit and the extinguishing element are all arranged inside the housing so as to provide for an autonomous operation of a self-contained protection device, where, in case of fire, the activating element is connected to the power supply such that extinguishing material is at activation temperature, and wherein the control unit is adapted to keep the temperature sensor switched on and to keep the smoke detector switched off until the inside temperature has reached a preset value, to switch on the smoke detector from the set temperature and to activate the extinguishing element when a concentration of smoke has reached a preset value.
