PURPOSE: To turn on respective lighting fixtures in accordance with the lighting pattern for power interruption even though the power recovery of a remote control transformer is delayed from the power recovery at the main power panel during restoration from a power failure. CONSTITUTION: Lighting information transmitted and output from a main operation panel 1 is transmitted to a relay control portion 6, and power control signals and relay control signals corresponding to the lighting information are generated. By the former signals, a remote control transformer 4 is automatically powered on/off, and power supply from the remote control transformer 4 by a relay 5 with the latter signals is intermittently supplied to the lighting fixtures. At the time of a power failure, power supply to a main operation panel 1 and the remote control transformer 4 is recovered by a private power generation source 9, and the lighting information is transferred to a lighting pattern for power interruption. Then, the lighting pattern for power interruption transmitted and output from the recovered main operation panel 1 is latched by latching means 17, and the lighting fixtures 3 are definitely turned on from the lighting pattern latched for power interruption when power is recovered for the remote control transformer 4. |
