IONIZATION SYSTEM AND CIRCUIT

PROBLEM TO BE SOLVED: To realize an ionization system and circuit in which an address control is made possible. SOLUTION: The ionization system 22 for predetermined areas is composed of a plurality of radiation source modules arranged here and there with spaces in the areas and is provided with at least one electric ionization device, radiation source modules 24 each containing a wrong wiring protection circuit system 70 in which, at a time of detecting a wrong wiring status, a relative location of at least two communication lines which have a fixed relation each other is changed automatically, a system controller 28 for controlling the radiation source modules 24 and a first communication line and a second communication line for connecting a plurality of the radiation source modules 24 with the system controller 28. The wrong wiring protection circuit system 70 changes automatically the relative location of the first and second communication lines so that the radiation sources 24 can be operated properly when wrong wiring status in a specific radiation source module 24 is detected.
