CONTROL METHOD OF THE FIRE DETECTOR

摘要

PURPOSE: A fire sensing device controlling method is provided to improve the reliability and the durability in consideration of deviation of incident light. CONSTITUTION: When a fire sensing device is turned on, a signal is detected by an auxiliary light accepting unit(S100). The reference value is selected by the signal of the auxiliary light accepting unit(S130). The light accepting unit signal is detected(S200). In case that the light accepting unit signal is detected, it is determined whether the fire broke or not(S300).
