An apparatus for detecting a hazardous condition including fire, smoke or both includes an optical module for measuring scattered light caused by the hazardous condition, wherein the optical module is configured to output at least one signal indicative of the scattered light, at least one temperature sensor configured to output at least one signal indicative of a temperature in proximity of the temperature sensor, and a humidity sensor configured to output at least one signal indicative of humidity in proximity of the humidity sensor. The apparatus includes further a processing unit coupled to receive the signals from the optical module, the at least one temperature sensor and the humidity sensor, wherein the processing unit is configured to process the signals to determine a plurality of criteria and to use these criteria to distinguish one or more deceptive phenomena from a hazardous condition in order to limit false alarm warnings and to enhance a detection performance. |
