Phone Line Trouble

Phone line problems that are not corrected can
result in the panel going into Communications
Failure. You can program the D9412/D9112 to
monitor one or two phone lines. See the D9000/
D7000 Series Program Entry Guide (74-07695-
000) for programming instructions.
If you enable the phone line monitor, SERVC
PHONE LINE #1 (or 2 if two lines are used)
appears in the Command Center's display when
the panel detects a problem on the phone line.
Remedy
1. Verify that the telephone cord is correctly
connected to the RJ31X and the panel.
2. Verify the Ground Start Jumper is in the
correct position.
3. If using a ground start phone line, verify
D136 relay is in socket K6/J5.
4. Verify that the RJ31X jack is wired
correctly. The incoming phone line must
be wired to terminals 4 and 5. The in-
house phone system must be wired to
terminals 1 and 8.
5. Verify that all telephones are on-hook.
Leaving a telephone on hold after the
other party hangs up creates an off-hook
condition. Verify that no phones are on
hold.
If completing the steps above does not
restore the phone line, meter the phone
lines. You should meter 4.5 to 7.5 VDC when
the line is idle (on-hook). You should meter 8
to 13 mA of current when the line is active
(off-hook). If your readings are below the
minimum values, contact your telephone
company repair service.
