1.3.3 Relay Boards
Each Relay Board has 12 relays on it numbered 00 through 11. One relay board is required for every
12 phone lines that the system interfaces with. These relays are identified to the main processor as a
four digit relay number beginning with 0000 and increasing sequentially up to the maximum of 1199.
Each cabinet has a label which identifies the cabinet number and the system relay numbers.
 Relay boards in the main cabinet are numbered 1 – 5. Relay board 1 is at the bottom, relay
board 5 is at the top.
 Set the board jumpers on the relay board to correspond with the board number. For
example, relay board 1 jumper is set to 1; relay board 2 jumper is set to 2; and so on.
 If a relay board is replaced, be sure to set the jumper on the new board correctly. Likewise, if
a relay board is moved to another location, the jumper must be set to correspond to the new
location.

Decoder Boards identify the Auxiliary Cabinets to the main control board by the setting of the cabinet
selector switches on the decoder board. Each auxiliary cabinet installed with the system requires 1
decoder board.
 Set the cabinet selector switches to correspond with the auxiliary cabinet number as shown
on the chart.
 If a decoder board is replaced, be sure to set the cabinet selector switches on the new board
correctly. Likewise, if a decoder board is moved to another cabinet, the selector switches
must be set to correspond to the new cabinet.
