Method for remote measurement, remote signalling and remote control, particularly applicable to the detection of fire and intrusion and to illumination

摘要

The method comprises a circuit for bidirectional communication between a central processing unit and apparatuses emitting or receiving logic or analog signals and is characterised in that these apparatuses are disposed in sequence over a common line (L) and in that the processing unit (UT) works by cyclic scanning of the various apparatuses (X) associated with identification circuits (UR).
