Abstract
A monitoring system having physical condition detectors arranged at places remote from a central receiving device so as to detect changes in the physical condition of a matter to be observed such as temperature, light and smoke. The central receiving device impresses detection mode signals on the output portions of detectors to control the outputs thereof. When said receiving device receives an output fed from said detectors by one of detection mode signals, said receiving device displays a physical condition of matter responding to the detection mode signal, thereby enabling the physical condition of matter to be continuously observed responding to detection mode signals and according to the lapse of time.
