摘要： Systems and methods for measuring and modifying an input voltage provided to a control panel are provided. Some systems can include measuring the input voltage provided by a power supply, determining whether the input voltage is within a range of acceptable input voltages, transmitting, to the power supply, a modulated signal on a direct current line between the power supply and the control panel instructing the power supply to modify the input voltage, and generating a notification when the input voltage is outside of the range of acceptable input voltages.
