  • Detection system and method for the verification of the functioning of the detection system by instantaneous comparison of the state of a node on a receptor and a node on a detector
    Patent number: 5450059
    Abstract: Detection system with receptor controlled by an emitter and having a microcontroller and a device to verify the proper functioning of the receptor which includes an additional control circuit connected to the receptor and to a terminal of the microcontroller. The microcontroller includes a generator-programmer which controls at time intervals the emission of a signal to activate the additional control circuit which forces the receptor to assume its non-conducting state, and which analyzes the corresponding instantaneous state of a node of the detector in such a manner as to prevent the control center from directing the control circuit if its instantaneous state is different from the inactive state.
