Appendix E: Direct Connection Wiring
You can connect your voice terminal locations in either of two ways:
●
Through the building wiring to a jack field at the control unit location.
or
●
Directly, with modular voice terminal cords and, if necessary, modular
voice terminal extension cords.
Jack field wiring is the recommended method for almost all cases. This
method is illustrated and explained throughout this manual. However, if you
need to use direct connection wiring, use the following instructions.
DIRECT CONNECTION
Follow these steps to connect your voice terminal locations directly to the
control unit:
1

Make a note of each voice terminal location you have selected for each
intercom number. Keep in mind that you may have to change intercom
number assignments later.
Mark or label each cord at both ends with matching labels, beginning
with 10. See Figure 48.
If the distance between a voice terminal location and the control unit
requires the use of extension cords, mark or label each end of the wiring
run.
Attach one label near the plug that goes to the voice terminal and the
matching label near the plug that goes to the control unit.
Run the cords from the voice terminal locations to the control unit.
CAUTION: Do not run cords inside air plenums or ducts, along hot pipes,
or across walkways. If you use staples to attach cords to walls or
baseboards, be careful not to pierce the cords.
Thread each cord through the bottom channel of the control unit and up
to the voice terminal jack with the same number as the cord label and
plug it in. Refer to the label on the power module to check the number
assignments for the voice terminal jacks.
