Essay

Method of determining time characteristics of thermal fire detectors in their autonomous tests is proposed and proved. Mathematical model of average volume indoor temperature at the initial stage of fire is constructed. Stochastic model of fire in the room is justified. It considers a stochastic character of heat from fire and describes the change of average volume temperature as a stochastic process. Methods of determining the time constant of sensitive element of fire detector by autonomous tests are justified. They are based on separation of the mean of output signal of sensitive element.
