Abstract
A device includes a connection receiving power from a power source under normal conditions and circuitry configured to determine, based on an input from the connection, when the power from the power source is absent; output, when the power source is absent, a test signal at the connection; and generate a detection signal based on current flow generated following the output of the test signal, wherein the detection signal indicates a position of a switch connecting the circuitry to the connection and the generated detection signal indicates the switch is closed when the current flow is above a threshold. The circuitry is configured such that when the power from the power source is absent, the switch is closed, and plural devices are connected on the supply side of the switch, the plurality of devices on the supply side appear as a substantially open circuit to the test signal.
