DoorKing 1982-010 Relay Board allows the Access Plus system to interface with an additional 12 phone lines when being used in the telephone intercom mode. To determine the number of relay boards needed, divide the total number of phone lines by 12, round up to the nearest whole number. IE: 270 phone lines ÷ 12 = 22.5. Round up to 23. For 270 phone lines you will need 23 relay boards. Order one RJ71C Phone Block & one 1882-042 Connecting Cable for each relay board in the system Decoder boards are required if the 1816 system expands beyond five relay boards. Order one 1881-010 Decoder Board for every eight relay boards added to the system after the first five relay boards.
