The wires on the RJ31 that feed pins 4 and 5 should be the ONLY wires on the D-marc. All other house phone wiring
should be tied to pins 1 and 8 coming back from the RJ31.
Dial tone must come into RJ31X on pins 4 and 5 and go back to house phones from pins 1 and 8. Follow these steps
to determine if panel is seizing the line:
1. Unplug phone cord from RJ31X
2. Place butt-set on pins 4 and 5
3. Listen for dial tone. With dial tone present, lift either wire from pins 1 or 8
4. Listen for dial tone again. If the dial tone is present, RJ31X wiring is correct. If no dial tone is present, the
RJ31X wiring is backwards. Rewire so dial tone is coming IN on 4 and 5.
If you still have trouble with the phone line, you may need to replace the RJ cord. If the dial tone is still not
present, swap out the RJ31X phone block.
