Abstract: A flame detector includes a UV sensor sensitive to solar UV radiation and a secondary sensor sensitive to non-UV radiation. A controller is operatively connected to the UV sensor and the secondary sensor to: signal an alarm in response to receiving input from the UV sensor indicative of a strong UV source and input from the secondary sensor indicative of a weak non-UV radiation source; and suppress an alarm in response to receiving a signal from the UV sensor indicative of a strong UV source and a signal from the secondary sensor indicative of a strong non-UV radiation source.
