Tri-color LED indicators at each key position guide the user to quickly locate keys, and provide clarity as to which iFobs a user is allowed to remove. Green indicates a key position that a user is authorized to access, red is a position the user is not authorized to access, and amber shows key positions that are current out of system. Another function of the LEDs is that they illuminate a pathway to the correct return position, should a user place a key set in the wrong place. Receptor Strips come standard with 10 key positions, but are available in double-density 20-position strips for special applications.
