PURPOSE:To facilitate the installation work by collating the load circuit numbers in the lighted state when an individual operation switch is operated and the stored load circuit numbers after an all-on switch is operated, and controlling the on/off of an all-on display lamp. CONSTITUTION:A parent unit 1 transmits on-signals to lighting loads 6 of all control terminals 5 when the all-on switch 31 of a pattern monitoring terminal 3 is operated and turns on an all-on display lamp 33. The load circuit numbers of lighting loads 6 receiving the lighting responses from individual control terminals 5 after the all-on switch 31 is operated are stored. When the individual operation switch 41 of an individual operation switch monitoring terminal 4 is operated, the load circuit numbers of the lighted display lamps 42 and the stored load circuit numbers are collated, if all lighting loads 6 with the stored load circuit numbers are lighted, the all-on display lamp 33 is turned on, if any one of the lighting loads 6 with the stored load circuit numbers is not lighted, the all-on display lamp 33 is turned off. |
