Wiring readers
To wire a reader:
1. Mount the reader. Refer to the manual that came with your reader for specific mounting instructions.
2. Run cable from the reader to the controller. Bring each reader cable through the appropriate knockout
hole in the controller cabinet. Allow some slack wire for servicing the cables and for plugging the
cable into an adjacent slot for troubleshooting.
3. Remove eight inches of insulating material from the cable. Unwrap shielding and tie all shields
together. Connect the communications cable shield to the ground nut adjacent to the cable entrance
knockout of the cabinet enclosure. For more details, see
Figure 73, Typical installation using shielded
cable/drain wire - outside and inside the enclosure on page 144.
4. Place the appropriate wires to the appropriate screw terminal on the 8RP reader board. Refer to the
reader wiring diagrams in this section. Pairing of cables is very important.
5. Label each cable end with Controller Address Number/ Device or Reader Number.
It is recommended that 20-AWG shielded cable be used for wiring reader DOs and DIs. Use plenum-
rated cable for applications where cable is to be run above the false (suspended) ceiling in the air
circulation space.
The following cable types are recommended:
• Alpha Xtra Guard1® foil shield cable, non-plenum rated, and
• Belden security and alarm cable (commercial applications shielded), plenum-rated.
CAUTION: The 8RP board has built-in pull-up resistors. Do not install the external pull-up resistors supplied with
the UTC/GE Proximity Readers.
