Notes: * The Group Lockout function allows the housekeeper manager to invalidate the
last guest's keycard when the room is ready. The Group address should be
assigned according to the duties of housekeepers and the housekeeper
manager.
** In order to use the Back-Up Keycard Kit, properties with two or fewer FDUs
should set all locks to Group 1 and assign a different Area number to each guest
room.
