A system for generating a humanly perceptible signal at one or more predetermined points in time, at which one or more medications must be taken or a time-dependent medical procedure must be implemented, includes a control unit at which the time or times are stored, and which includes a time measuring unit which provides a signal upon the occurrence of the time or times, and at least one signaling device disposed remote from said control unit, which receives a signal via a communication system from the control unit and which emits a visually perceptible reminder upon receipt of the signal. The control unit and the signal device are disposed in a building which is occupied, or can be occupied at times, by a patient, and the communication system is integrated as a part of the building.
