PURPOSE: To control respective console units simultaneously and also to control a group corresponding to an optional group address simultaneously in a remote controlling device to control a main operation monitoring panel and plural console units independently by a time division multiple signal, by providing the device with the 1st and 2nd console unit logical circuit parts.

CONSTITUTION: When the 1st console unit logical circuit part 16a is controlled from the main operation monitoring panel, the data of a control output 1 are sent to a relay driving part 28 through a latch circuit 33. When a control signal is sent to a group address from the main operation monitoring panel, an one- shot pulse is generated from a relay driving output of the 2nd console unit logical circuit part 16b and inputted to the relay driving part 28 through an OR gate 32 as a relay driving signal and the data of a control output 1 of the 1st console unit logical circuit part 16a are latched to the 1st latch circuit 33 and outputted to the relay driving part 28 to drive a control relay 29. The main operation supervisory panel controls respective console units simultaneously and also can control a group corresponding to a group address.
