1. GENERAL DESCRIPTION

The RS-142 is a switch board to be connected to the 2-Core Shielded Substation Interface Unit. You can
make desired switch panels to meet intended purposes by combining the RS-142 with the separately
prepared operation panel having 2 switches to be used as call buttons.
The RS-142 features handset conversations by using the RS-141 indoor-use Option Handset in combination.
