I can't be sure of the EXACT timing, but in my experience the first message that would be noticed is the EICAS alert 'NO LAND 3'. Shortly afterwards a 'STATUS' prompt would appear on the upper EICAS, alerting the flight crew to the existence of a new status message. However, as I said in an earlier post, the flight crew's subsequent actions would be dictated by the 'NO LAND 3' message, not by the status message.
If the 'NO LAND 3' alert appears before 1500 ft RA during the approach, then it's advisory only and there's no aural alert. If, however, the 'NO LAND 3' alert appears after 'LAND 3' is already annunciated on the AFDS (ie below 1500 ft RA), then it becomes a caution and there will be an aural alert (ie a beeper).
