A reduced pressure treatment system includes a processing unit, a reduced pressuresource, and a conduit fluidly connected between the reduced pressure sourceand a tissue site of a patient. The reduced pressure source is configured to operateat a target power level to apply a reduced pressure to the tissue site. A canisteris provided to collect fluid drawn from the tissue site. A sensor is provided incommunication with the reduced pressure source to determine a source pressureat the reduced pressure source, and an alarm indicator is provided in communicationwith the processing unit. The processing unit communicates a leak alarm signalor a canister disengaged alarm signal to the alarm indicator when an actual powerlevel of the reduced pressure source exceeds the target power level for a selectedperiod of time.
