The FB-1 is a mounting bracket for Fixture Mount sensors that solves the problem of having a field-of-view that is partially blocked by the side of the fixture to which it is mounted. The FB-1 mounts to a 1/2 inch knockout on a fixture and contains a channel through which the Fixture Mount sensor's wire are routed. The sensor is then mounted to the FB-1 through another 1/2 inch knockout.
