An occupant support suite comprises a bed (20) an acoustic sensor (110, 110A) associated with the bed for receiving an acoustic signature (160) corresponding to a stand alone device (150) and a processor (112, 112A) for comparing the signature to a library (116) of reference signatures, and, if the comparison is satisfactory, issuing a notification (208) to the bed, to an off-bed destination (210) or to both.
