Abstract: Fuel burner supervisory system wherein a pair of flame sensors are located close to the flame being supervised, periods of flame absence are simulated for each sensor, elements are respectively responsive to the sensors to assume a trouble state when an associated sensor indicates the absence of flame other than during a period of simulated flame absence, or when the sensor indicates the presence of flame during a period of simulated flame absence, and a flame failure alarm is connected to signal when both elements are in their trouble states, thus indicating a likely absence of flame.
