110 Concord 4 Installation Manual
The negative red lead or (RING) wires must connect to terminal 28 on the
board.
2. Concord panels are voltage sensitive, so it’s necessary to check for proper
voltage:
On hook voltage should be approximately 48-52 volts.
Off hook voltage should be approximately 6-10 volts.
Note: The Concord panel has a built-in line voltage meter. If it does not see
proper voltage, it will not dial on a tone phone line. This does not apply to a pulse
phone line.
To check proper phone line with line seizure:
1. Check the type of phone line. Concord panels work with analog phone lines
or DSL with a DSL filter inline to the panel. VOIP or digital phone lines may
not work with the panels.
2. Check that the premise’s phone line is working.
3. Check that the DB-8 cord is plugged into the RJ31X/CA-38A jack.
4. Check for correct phone line wiring between the TELCO block and the
RJ31X/CA-38A jack.
