  • Abstract
This paper analyzes the heat transfer principle of temperature sensor fire detector, establishes mathematical model of heat transfer with considering the effect of radiation heat transfer and presents a new calculation method for the response time. The results of calculation show that when the environment temperature is rather low and the response temperature is set higher, the effect of radiation heat transfer on response time shouldn't be neglected. This paper may be helpful in appraising fire safety and designing alarm system.
