Backlight Functionality
When the system is Stay or Instant armed, the intensity of the
keypad's backlight automatically decreases to a Level 1 setting.
During this time, if a key is pressed on the keypad, the backlight
switches to regular intensity and then returns to the Level 1 setting
when all actions on the keypad cease. The backlight returns to
regular intensity when the system is no longer Stay or Instant armed.
