Abstract
An emergency dimming apparatus including a control input pass-through configured to receive a control signal, a control output configured to output the control signal to a driver, and a controller. The controller includes an electronic processor and a memory. The controller is configured to monitor a line voltage, determine if the line voltage has crossed a threshold, disconnect the control input pass-through when the line voltage has crossed the threshold, output an output voltage when the line voltage has crossed the threshold, and output an emergency control signal, via the control output, when the line voltage has crossed the threshold.

An emergency dimming apparatus comprising:
- a control input pass-through configured to receive a control signal;
- a control output configured to output the control signal to a driver;
- and
- a controller including an electronic processor and a memory, the controller configured to monitor a line voltage,
- determine if the line voltage has crossed a threshold,
- disconnect the control input pass-through when the line voltage has crossed the threshold,
- output an output voltage when the line voltage has crossed the threshold, and
- output an emergency control signal, via the control output, when the line voltage has crossed the threshold.
A method of operating a light, the method comprising:
- monitoring, via a controller, a line voltage;
- disconnecting a control input pass-through when the line voltage is below the threshold;
- outputting an output voltage when the line voltage is below the threshold;
- and
- outputting an emergency control signal when the line voltage is below the threshold.
