Troubleshooting
WCI does not join network
Tracer SC does not communicate with WCI
Sensor does not communicate with WCI
Note: Error code E7 appears on sensor.
Possible cause Explanation/Resolution
Not enough time allowed for joining.
Give the WCI more time to join. If the network closes before the WCI has joined, re-
open if necessary by pressing the OPEN NET button.
Wrong address
For factory addressed WCIs, verify addresses with equipment report.
Verify each WCI address after installation.
If sensor is installed, check for error code at sensor.
Initiate network formation and resolve by exception.
No power
Ensure that:
• The WCI is wired correctly.
• The corresponding controller is wired to equipment correctly and is powered On.
Too much traffic
Try a different channel. A better channel may be found by trial and error or by using
a tool such as WiSpy.
Outside of radio range or too many obstacles Relocate WCI
Defective WCI Replace
Possible cause Explanation/Resolution
No power to the WCI Ensure that the WCI is wired properly to the Tracer SC
Wireless link on the Tracer SC
Ensure that the wireless link on the Tracer SC is enabled and configured to match WCI
address, and is unique within the building.
One of the devices is outside of radio range
Move network components to within radio range or break up networks to make smaller
so that all components are within radio range.
Possible cause Explanation/Resolution
Sensor/unit controller address mismatch
Ensure that the sensor address matches the unit controller address.
Note: Be sure to match addresses rather than the direction of the arrows.
No power
