Phone Line Trouble

Phone line problems that are not corrected can result in the panel going into Communications Failure. The D9412G/D7412G
can be programmed to monitor one or two phone lines. See the D9412G/D7412G Program Entry Guide (P/N: 47775) for
programming instructions. If the phone line monitor is enabled, SERVC PHONE LINE #1 (or SERVC PHONE LINE
#2 if two lines are used) appears in the command center's display when the panel detects a problem on the phone line.
System
SERVC PH LINE #1 (or
SERVC PH LINE #2 if two
lines are used) appears in the
command center display.

Diagnosis
More than one
command center has
the same supervised
address.
Data connections
(yellow and green
wires) on one or
more command
centers are reversed,
or only one wire is
connected.
Check the User Interface section of the program to be sure the function is
enabled for the authority level assigned to the passcode in the Passcode
Worksheet section of the program.
Check the Passcode Worksheet section of the program to be certain the passcode
is assigned to the area where you are attempting to perform the function.
Check the Passcode Worksheet section of the program to see if the passcode is
restricted by a user window.
Check the Area Parameters section of the program to be certain the area in
which you are attempting to perform the function is turned on.

Remedy
Use a supervised address in one command center only
or use a different supervised address for each
command center.
Check that yellow and green data wires are correctly
connected on all command centers.
Remedy
Verify that the telephone cord is correctly
connected to the phone jack and the panel.
Verify the Ground Start Jumper is in the correct
position.
If using a ground start phone line, verify a D136
relay is correctly installed in the Ground Start Relay
socket.
Verify that the phone jack (RJ31X or RJ38X) 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.
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 line. You should meter at
least 3.0 VDC. If your readings are below the
minimum values, contact your telephone company
repair service.
