A detection system for measuring one or more conditions within a predetermined area includes a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining a node arranged to measure one or more conditions within the predetermined area. A control system is operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the light transmitted from the node by comparing multiple wavelengths of scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node.
