Abstract: A fault circuit indicator (FCI) detection system for electrical equipment disposed in an enclosure or vault having an above-ground vent pipe exhaust outlet comprises one or more sensors disposed in the enclosure or vault to sense a condition of at least one unit of the electrical equipment. A sensored analytics unit (SAU) is coupled to the sensors to receive sensor data and analyze the sensor data, the SAU generating a corresponding analyzed data signal that provides information related to a condition of the at least one unit of electrical equipment. A transceiver is disposed inside at least a portion of the vent pipe to receive the analyzed data signal, wherein the transceiver is configured to communicate the analyzed data signal. A visual indicator is disposed on or within the vent pipe comprising one or more visual indicators, such as LEDs, driven by a driving circuit board to provide a visual signal corresponding to the condition of the at least one unit of electrical equipment.
