Abstract
An embodiment of a flame detector coverage verification system includes an optical source for generating a light beam, and a light-path control unit connected to the optical source and configured to direct the beam through a range of movements about a center line direction of the flame detector to visually demarcate an area that falls within the flame detector's field of view. An indicator device configured to visually indicate a pan direction of the detector optical center line. A tilt indicator is configured to determine and visually display the tilt angle of the detector with respect to a ground plane. A hub structure temporarily attaches the control unit to the flame detector, the control unit pivotally connected to the hub structure so that the optical source light beam is oriented perpendicular to a ground plane.
