Abstract
A flame detector system (10) includes a flame detector (10) and a plurality of targets (22). The flame detector includes a housing (30), a flame sensor (32), an imaging device (34) having an optical view (70) that correlates to the field of view (50), and a controller (24) in communication with the imaging device. The plurality of targets are disposed within the optical view. The controller is programmed to operate the imaging device to capture a first image of an external environment (26) containing the plurality of targets and store the first image and a location of the plurality of targets within the first image.
