A multi-sensor type sensor has sensor processors for generating detection data of plural types based on detection signals from a plurality of sensor portions, and a mode switching portion for switching a mode which indicates type of data to be sent to a receiver in response to a mode switching instruction issued from the receiver, and sending selectively the data of the type which corresponds to a current switching mode in response to a data request instruction issued from the receiver. The receiver includes a mode switching indicating portion for switching the mode by transmitting the mode switching instruction which selects type of response data to the fire sensors, and a fire judging portion for judging the fire by receiving the response data from the fire sensors in response to transmission of the data request instruction.
