Fire detectors with touch panel

Fire detectors are installed locally units which are mounted, for example on a ceiling or on a wall and serve to detect a fire in the vicinity thereof. In the invention, a fire detector 2 is proposed for a fire alarm system 1 for monitoring a monitoring area 3, with an interface 12 for communicating with the fire alarm system 1, with a sensor device 7 for the spatially resolved recording of the monitored zone 3 in an infrared wavelength range, and for outputting sensor signals , having an evaluation device 9 to determine a fire condition by analyzing the sensor signals of the sensor device 7, wherein the fire condition is transmitted via the interface 12 to the fire alarm system 1, wherein the sensor device 7 comprises a sensor array, which outputs a sensor signal, a measured value field.
