PROBLEM TO BE SOLVED: To conjointly operate the same ventilation fan by a plurality of different lighting control systems without providing separate wiring. SOLUTION: This slave unit C for interlocking the ventilation fan is equipped with two slave unit connecting terminal parts 3, 4 to which the signal wires Ls1, Ls2 of respective different lighting systems are connected. A control part 9 operates the ventilation fan F by controlling a ventilation fan driving part 8 when a human body detecting signal is input from at least either one of the slave connecting terminal parts 3, 4. Accordingly, the same ventilation fan F can be conjointly operated by two different lighting control systems without providing separate wiring as in the case of a conventional example.
