Abstract

PURPOSE:To turn on or off all loads via the emergency signal generator in case the transmitter has some fault by securing the individual ON/OFF control for the load which is connected to the terminal unit via the control signal given from the transmitter. CONSTITUTION:The control signals are applied to terminal units 51-5n from transmitter 2 via signal line 4. Each terminal unit is selected by the address code of the control signal to give the lighting control to illuminating tools 6a1-6dn which are the loads by the control signals following the address code. In case the transmitter has some fault, the illuminating tool is kept under the state of the control signal before occurrence of the fault. In this case, if switching is given to the side of emergency signal generator 7, the emergency signals are transmitted to light up all illuminating tools. In such way, a collective control can be given to all loads to the prescribed safety side via the emergency signal generator.
