Abstract
This circuit includes a DC source in series with a load to be energized, the DC source also being coupled to a constant-current circuit coupled to the input of an output-signal-generating means. The latter produces an output signal in response to the detection by an associated sensor of a changing condition monitored by the sensor. When the signal-generating means detects a change, an SCR coupled to the DC source is turned on thereby by-passing all of the DC from said source around said constant current source. Simultaneously, the signal-generating means causes an associated LED to emit a light signal.
