Introduced in version 8.7, Micros Fidelio Suite 8 now supports a Pre-Arrival function (also called Energy Management System Scheduler). Pre-Arrival is a Room Equipment record which is sent by the PMS to connected BMS systems prior to the expected arrival and room occupancy by a guest.
The use of this function is to allow the BMS to prepare the room’s climate control. Unoccupied rooms can be operated in economy mode. With Pre-Arrival information there is enough time for climate control to ensure a convenient temperature when a guest enters their room.
By default, the Pre Arrival Status enumeration in the room point’s proxy extension will be set according to any Pre-Arrival message received via a FIAS Class of Service (CS) record. Collection and visibility of this data may be disabled by a setting in the Micros Network/Link Config/Pre Arrival Config.
The FIAS protocol manual suggests the following:It is recommended that BMS systems support Room Equipment (RE) record with Class Of Service. CS values could e.g. be interpreted as:
These pre-arrival records can only be RoomEquipment (RE) records. Fidelio will send an additional GI record once the guest actually arrives.

If no Pre Arrival Status value is set for a room then the status of the Enum point is set to {stale} which indicates the value has not been sent since the last guest event on the room.
A Micros Setpoint Select Component, available in the micros palette, when added to the proxy point can reduce the strategy needed to manage setpoint selection with Pre-Arrival signals. See micros-MicrosSetpointSelect component.
Pre Arrival Status values are not sent during Database Sync and the driver sets them to {stale}. We assume Database Sync is only invoked when the two systems have inconsistent data.
It should not be considered unusual during normal operation, to observe that a point has normal occupancy data but has a stale Pre Arrival Status value. A Pre Arrival Status value of {ok} confirms that the value has been sent from the PMS server since the last guest movement or Database Sync event.
