System and method for monitoring a working status of a swimming pool cover assembly. The system comprises a pool cover assembly operably connected to an alarm apparatus; both may be operably connected to a plurality of sensors capable of detecting a working status of the pool cover assembly and sending a signal to the alarm apparatus. The alarm apparatus continually produces at least one humanly perceptible indication corresponding to a working status of the pool cover assembly. The alarm apparatus includes at least one alarm-producing device, such as an audio or visual device, or combination of the two, a receiver operably connected to the plurality of sensors for receiving the signals, a processor operably coupled with the receiver for processing and recognizing the received signals, and software operably coupled with the processor enabling the alarm-producing device to produce the humanly perceptible indication corresponding to the recognized signal.
