An infusion system to administer a fluid includes an infusion pump with a pump processor, a pump memory to store a plurality of configurable alarms and a pump radio to enable bi-directional communication. The infusion system further includes a controller that has a controller processor, a controller memory, a controller radio to transmit and receive communication from the pump radio. The controller further has a graphical user interface shown on a display along with controls to manipulate the graphical user interface. Furthermore, the bi-directional communication between the infusion pump and the controller establish an infusion pump relative proximity between the infusion pump and the controller such that when the infusion pump relative proximity exceeds a pump threshold distance at least one of the plurality of configurable alarm conditions of the infusion pump is modified.
