Wireless Comm
Only qualified personnel should install and service the equipment. The installation, starting up, and
servicing of heating, ventilating, and air-conditioning equipment can be hazardous and requires specific
knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person could
result in death or serious injury. When working on the equipment, observe all precautions in the literature
and on the tags, stickers, and labels that are attached to the equipment.

  • Page 18 Establishing the Network On power-up, the WCI goes through a check list and updates LED activity according to the type of device associated with the WCI and the status of the WCI in the network. The LED flash patterns vary depending on current conditions. LED behavior is described in Table Table 2.

    Establishing the Network Three Ways to Establish a Wireless Network A wireless network can established: • After a Tracer SC has been installed. • Prior to Tracer SC installation. • On a network that will not have a Tracer SC installed on it. Establishing the Network After Tracer SC Installation If a Tracer SC is installed prior to establishing the wireless network, the WCI that is installed on a Tracer SC automatically becomes the network coordinator after power is applied to the Tracer SC.

    Establishing the Network 3. Observe the yellow OPEN_NET LED illuminate on the coordinator WCI. This LED remains lit for 1 hour, indicating that the network is open to allow WCIs with matching addresses to join the network for that duration. After each WCI joins, the 1 hour timer starts over. Notes: If the network closes because the timer has expired, you can open the network for an additional hour by pressing the OPEN_NET button.

    Modifying the Network This section describes how to modify an established wireless network. Most modifications can be made by using either the Tracer TU service tool or the WCI. To use Tracer TU, you must establish communication with a wireless network and attach to a wireless device.

  • Page 23: Removing A Wci From A Network

    Modifying the Network Removing a WCI from a Network If a coordinator WCI fails, the network ceases to exist. If the other WCIs that were members of the disbanded network find an open network within radio range, they will try to join that network. To prevent that from occurring, you can remove WCIs from the network until the coordinator WCI is replaced.

    Troubleshooting No communication Possible cause Explanation/Resolution If power loss causes communication to be lost, the coordinator WCI will re-initiate the Power loss network as soon as power is returned. If an obstruction causes communication to be lost, the coordinator WCI will re-initiate Signal obstruction the network as soon as communication is regained.

Attach the terminal block on the wiring harness to the receptacle on the new WCI and route the wires as before (through either the back plate or the bottom exit port). 9. If a Tracer SC is present on the network, restore power to the Tracer SC. The network will re- form itself.
