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:
1Make 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.
2Mark 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.
3Attach one label near the plug that goes to the voice terminal and the matching label near the plug that goes to the control unit.
4Run 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.
5Thread 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.
