Follow these general guidelines when installing communication wiring:

1)Maintain a maximum 5000 ft. aggregate run

2)Install all communication wiring in accordance with the NEC and all local codes.

3)Solder the conductors and insulate (tape) the joint sufficiently when splicing communication wire. Do not use wire nuts to make the splice.

4)Do not pass communication wiring between buildings be cause the unit will assume different ground potentials.

5)Do not run power in the same conduit or wire bundle with communication link wiring.

Establish service communication using Rover™ service software connected to the Tracer® ZN.520 using a twisted wire pair to one of the following connection points.

1)Remote zone sensor module

2)Connections on the board

This allows the technician to view and edit the Tracer® ZN.520 configuration and troubleshoot the unit. However, control options ordered and the wiring practice followed in the field may limit the communication ability.

Route interconnecting wiring from the Tracer® ZN.520 to provide service communication at the wall-mounted zone sensor module. Install wiring by referencing the unit wiring diagram and Table 3 on page 35 for appropriate wire sizes. After wiring is complete, connect the communication cable (provided with the Rover service tool) to the telephone style RJ11 connection on the zone sensor module. Attach the other end of the cable to a laptop computer running Trane Rover software to establish communication.

Establish service communication to the Tracer® ZN.520 by wiring directly to the board inside the control box. Reference the unit-wiring diagram for the appropriate communication terminals on the board. Once wiring is complete, Use Trane Rover software to communicate to the Tracer® ZN.520.
