Abstract: The aspects disclosed herein are directed to systems, methods, implementations, and devices for determining if optical fire detector location, orientation, and quantity is sufficient to view a target fraction of all fire scenarios, as determined by risk analysis (e.g., 90%, using an approach that considers the actual dimensions of the visible fire). Employing the aspects disclosed herein, an implementer may review a real-world implementation, or collection of fire detectors including their locations and orientations as determined by heuristics, such as placing fire detectors near potential leak locations, and determine if the proposed layout is capable of detecting the target coverage, or fraction of fire scenarios that are possible in a given situation.

Abstract: The aspects disclosed herein are directed to systems, methods, implementations, and devices for evaluating the efficacy of optical fire placement(s) with a plume-based model. Employing the aspects disclosed herein, an implementer may review a real-world implementation and determine if said real-world implementation is covered adequately by a proposed optical fire placement strategy.
