Abstract
A system for monitoring smoke and/or temperature of an electronic device includes a fiber harness having at least one fiber optic cable terminating at a node. The node is located to measure one or more conditions at the electronic device, and a control system operably connected to the fiber harness. The control system includes a light source configured to transmit light through the fiber harness, a light sensitive device configured to receive scattered light associated with the node, and a control unit configured to analyze the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node of one or more conditions at the electronic device, wherein the control unit is further configured to transmit a signal in response to the one or more conditions, wherein the one or more conditions are one or more of smoke, fire, and temperature.
