On the choice of fire detection principles by combined fire detector

Article briefly describes results of works on identification of fire factors, characteristic for burning substances which are most often used in everyday life. Most common factors of combustion substances classes “A”, “B”, “C” and their subclasses were identified. Analysis of the acquired data may be used to identify the burning substances. Fire detection methods which will be used in the combined fire detector are also chosen: temperature, smoke electro-optical and gas-analytical.
