Abstract
The present invention is directed to a sensor for detecting arcing faults, the sensor combining a photodetector, a pressure detector, and an accelerometer along with integrated circuitry. The circuitry controls each detector, operates the self-test circuitry, conditions the signals from the detectors, and communicates with the external network. The circuitry receives commands from the network and transmits the output decision from the sensor.
