Abstract

A system for locating a detection system within a predetermined area includes a fiber optic harness defining at least one node in communication with the predetermined area. Light is received at the at least one node. At least one emitter is arranged in communication with the at least one node. A control system is operably coupled to the at least one emitter and the at least one node to determine a physical location of the at least one node relative to the predetermined area.
