A fire control unit (102) for ascertaining presence of fire in an aircraft is described herein. In one implementation the fire control unit (102) includes an analog-to-digital converter (106) to receive analog signals generated from a plurality of sensors (104), where the analog signals correspond to temperature a region of the aircraft, measured by each of the plurality of sensors (104); and convert the analog signals to digital signals of a pre-determined bit width. The fire control unit (102) also includes a signal processing unit (108), coupled to the analog-to-digital converter (104), to determine voltage corresponding to the digital signals to be in a pre-determined voltage range for a pre-determined time interval, for ascertaining the presence of fire in the region.
