Open the right door of each jack panel box in the jack field.
TIP: The labeling inside the right door should indicate the wiring run
number and endpoint for each jack in the box. Use this labeling as a
guide when you fill in your system directory and connect the jacks in
the jack field to the voice terminal jacks on the control unit.
In the system directory, fill in the voice terminal location (the wiring run
endpoint) for each intercom number.
Beginning with the pair of labels marked 10, label both ends of each
jumper cord with matching jumper cord labels.
Plug one end of the cord labeled 10 into voice terminal jack number 10
on the control unit.
Following the system directory and the jack field labeling, plug the other
end of the cord into the jack in the jack field for the voice terminal loca-
tion to which you have assigned intercom 10.
Repeat the procedure for each jumper cord, and close the doors on the
boxes when you’re finished.
Peel the backing off the system directory, and attach the directory to
the inside of the control unit’s door.
Fit the door onto the front of the control unit.
