DANGER DETECTOR WITH A NON-CONTACT HEAT RADIATION SENSOR FOR DETECTING AN OPEN FIRE AS WELL AS TO DETERMINE AN AMBIENT TEMPERATURE

The hazard detector has a detector housing with a detector hood, where a heat radiation sensor (4a) is arranged in the detector housing. A processing unit (4b) is connected downstream to the heat radiation sensor for further processing of a sensor signal (SIG) that is outputted from the heat radiati...

Beschreibung
Zusammenfassung:The hazard detector has a detector housing with a detector hood, where a heat radiation sensor (4a) is arranged in the detector housing. A processing unit (4b) is connected downstream to the heat radiation sensor for further processing of a sensor signal (SIG) that is outputted from the heat radiation sensor. The processing unit monitors the sensor signal on the occurrence of significant fluctuations or flicker frequencies for open fire. An independent claim is included for a method for detecting an open fire and for determining the temperature value in the vicinity of a hazard detector.
