摘要： An example sensor may include an omnidirectional reflector, a calibration source located inside the omnidirectional reflector and configured to generate one or more calibration beams, a first filter configured to filter one or more first beams including any of a first portion of the incoming beams collected and concentrated by the omnidirectional reflector, and a first detector configured to detect the filtered one or more first beams.

摘要： Methods and systems for testing a flame detector (200) include receiving, at a trigger sensor (212) of the flame detector (200), a coded trigger signal from a test lamp (300) and performing a self-test operation of the flame detector (200) in response to detection of the coded trigger signal. The flame detector (200) may include a trigger sensor (212) configured to detect a trigger signal received from an external source. The trigger sensor (212) has a field-of-view and sensitivity that is the same a flame detection sensor of the flame detector (200). The flame detector (200) will perform a self-test operation when the trigger signal is received at the trigger sensor (212). The test lamp (300) includes a light source (302) configured to emit light and a controller (304) configured to control the light source (302) to generate and output a trigger signal, wherein the trigger signal is configured to cause the flame detector (200) to perform the self-test operation.
