Voice Terminal Wiring - AT&T MERLIN 820 Installation Manual

Voice Terminal Wiring

The intercom number for each voice terminal in your MERLIN system is the
same as the number of the voice terminal jack in the control unit to which that
voice terminal is connected. On a Model 820 control unit, the voice terminal
jacks are labeled 10-29. If you want a particular intercom number at a specific
location within your business (for example, intercom 10 at the attendant's loca-
tion), make a note of the assignment now, before you begin connecting the voice
terminal locations to the system.
As noted in "Getting Started," you can connect your voice terminal locations
to the control unit in either of two ways: (1) directly, with modular voice terminal
cords and, if necessary, modular voice terminal extension cords; or (2) indirectly,
through the building wiring to a jack field at the control unit location.
Whichever procedure you use, you need the following items from the installa-
tion kit to complete the connections:
System directory
You've already recorded the telephone numbers for your outside lines on it.
Modular jumper cords
You should have one 2½-foot cord for each voice terminal in your system.
If you have a professionally installed jack field, these cords may be hang-
ing from the jacks in the jack field. If they are, remove them now.
Blue-on-white jumper cord labels
The labels are numbered 10 through 29. You should have a matched pair
of labels for each cord.
The next two sections give directions for a jack field connection and a direct
connection. Go to the section that applies to your system and do what it says.
