Abstract
An apparatus and method adapted to detect a failure in at least one lamphea d of an emergency lighting system includes a signal generator and a failure sensor. The lamphead receives power from a power connection. The signal generator generates a monitoring signal having a voltage, which is operatively coupled to the power connection. The failure sensor detects a failure in the lamphead and modifies the voltage of the monitoring signal. The emergency lighting system may also include a plurality of lampheads. In this case, the failure sensor may detect a failure in at least one of the lampheads, and identify which of the plurality of lampheads has failed. The failure sensor may also be adapted to reduce the voltage of the monitoring signal in response to detection of the failure.
