Troubleshooting
This section provides troubleshooting solutions to the most common issues if your Cellular
Gateway is not working correctly . If you are unable to resolve your issue, contact your local
Watts representative to order a replacement device .
Poor or No Cellular Reception
Poor or no cellular reception will cause notifications to not work . As noted in the Installation,
Operation and Maintenance Manual, the installation location is important for cellular reception .
If the CELLULAR LED is OFF or blinking, the most likely issue is poor reception . If the device is
still not working, review the possible causes and solutions below .
Possible Cause 1
The location where the antenna is installed may be interfering with cellular reception .
Note:
Care should be taken to ensure that the antenna side of the device is installed away
from any walls, wires, pipes, or other obstructions, particularly anything metallic .
Solution 1
Move the Cellular Gateway to a location where the antenna is not facing any internal walls,
wires, pipes, or other obstructions, such as an electrical box .
Possible Cause 2
The location has poor cellular reception .
Solution 2
Move your Cellular Gateway to a different location and check to see that the CELLULAR LED
is solid blue; if it is not, move the device until you find a location with better cellular reception .
Note:
You can install the Cellular Gateway up to 100 feet away from the Junction Box . Six
feet of wire is supplied with the Cellular Gateway . If additional wire is used, it must meet the
required rating for the Junction Box (300V, 16-24 AWG) .
Please consider the following before installing the Cellular Gateway outdoors:
• If the unit is installed outdoors, additional precautions may need to be taken to ensure the
wire entry at the bottom of the node is adequately sealed (with silicon or something similar)
to prevent water intrusion .
• Do not install in direct sunlight .
• Depending on the geographical location, condensation buildup inside the enclosure is a concern .
