Abstract: The present invention is directed to reducing non-fire alarms by distinguishing between smoke caused by an actual fire and non-fire smoke generated in daily life when an event suspected to be a fire occurs. The present invention provides an apparatus and method for determining whether a fire occurs using a smoke detector, which includes a light emitter for generating multiple wavelengths, a light receiver configured to detect light scattered by particles of smoke, and a fire determiner for checking whether the strength of a signal of the detected scattered light exceeds a threshold and generating an alarm, to use characteristics of multiple wavelengths in a photoelectric fire detection apparatus. The fire determiner calculates normalized values by normalizing measured values for the scattered light, and calculates a singular value from the normalized values as a criterion for determining whether the smoke is caused by a fire or a non-fire.
