METHOD AND DEVICE OF DETECTING FIRE AND DETERMINING ITS ORIGIN Russian patent published in 2008 - IPC G08B17/00 

FIELD: alarms systems.

SUBSTANCE: present invention pertains to the method and device for detecting and determining the origin of a fire in one or more controlled zones (R₁, ..., R_n), using a system (3) of suction pipes connecting several controlled zones (R₁, ..., R_n). The suction pipes are connected to each separate controlled zone (R_1, ..., R_n) using at least one air inlet duct (4), suction device (5) for tapping air samples (6), indicating the state of the air medium in the facilities of each controlled zone (R₁,_{..., Rn), from separate controlled zones (R1, ..., Rn) using system (3) of suction pipes and air inlet ducts (4), and sensor (7) for detecting at least one fire parameter in air samples (6) tapped off using system (3) of suction pipes. The device has blowing off device (8) for blowing off air sample (6), from the system (3) of suction pipes, when sensor (7) detects at least one fire parameter in the air sample. The origin of the fire is determined by measuring the arrival time of the sample, repeatedly sampled with fire parameters.}

EFFECT: possibility of detecting the origin of fire.
