      If your Tracer SC isn't communicating with the WCI, consider these factors: * **Power:** Ensure the WCI is correctly wired to the Tracer SC. * **Wireless Link:** Verify that the wireless link on the Tracer SC is enabled, configured to match the WCI address, and is unique within the building. * **Radio Range:** Make sure the devices are within radio range. If necessary, move network components closer or break up larger networks into smaller ones to ensure all components are within range.

      If the WCI (Wireless Communication Interface) fails to join the network, there are several potential causes and solutions: * **Time:** Allow more time for the WCI to join. If the network closes prematurely, reopen it by pressing the OPEN NET button. * **Address:** For factory-addressed WCIs, verify the addresses using the equipment report and after installation. If a sensor is installed, check for error codes. Initiate network formation and resolve any exceptions. * **Power:** Ensure the WCI and the corresponding controller are correctly wired and powered on. * **Traffic:** Try a different channel to avoid excessive traffic. Use tools like WiSpy to find a better channel. * **Range/Obstacles:** Relocate the WCI to ensure it is within radio range and that there aren't too many obs...
