An LCD display unit is attached to the front panel of a typical fire alarm system. The screen displays data (numerical value) pertaining to battery usage in the alarm system. The LCD is connected to the power source (batteries) in the alarm system. A battery icon displayed on the screen shows the user battery power level. Battery icon is fully charged when icon is completely colored (for this example battery will be colored in black). As battery power decreases so does the color of icon from FULL to EMPTY.
