Startup Sequence
When the Cellular Gateway powers up, the device goes through a startup sequence, which
includes the Startup LED changing colors until it turns off. Below is the startup sequence that
the device will go through if everything is working correctly. If the Startup LED blinks white for
more than 30 seconds or if it blinks green for more than 10 minutes, refer to Startup in the
LEDs section to troubleshoot the issue.
COLOR STATE DEFINITION
White Appears for a few seconds after the device is turned on.
White blink - slow
(5 sec)
The cellular radio is off; this is a normal state for five seconds.
Green blink
(30 sec - 10 min)
The device is searching for a cellular connection.
Cyan blink - fast A cellular connection has been established and the device is
connecting to the Cloud.
Cyan blink – slow A Cloud connection has been established.
Off The device is operating normally.
Power
The POWER LED turns on when power is supplied to the device.
COLOR STATE DEFINITION SOLUTION
Green The device is turned on. N/A
Off If the device is plugged in, but this
LED is not on, the device is not
receiving power.
The +12Vdc and GND wiring could be
reversed. See POWER LED is Off on
page 8.
LEDs
The LEDs inside the Cellular Gateway indicate if a component/connection is running, or if there
is an issue. The following sections describe the different LED colors and blink patterns.

Flood
The FLOOD LED only turns on when excessive relief valve discharge from your backflow
assembly is detected.
COLOR STATE DEFINITION SOLUTION
Orange Water is discharging from the relief
valve of your backflow assembly, and
it is more than a slight drip.
Note: This will only turn on if water
discharge is detected.
If your device is registered, you will
receive a “flood notification” via text,
email and/or a phone call.

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.

Troubleshooting (continued)
Possible Cause 3
Cellular reception might not be supported at your site.
The Cellular Gateway operates using 3G technology on band 2 or 5. Mobile phone
reception is not a reliable indicator of expected signal strength for the
Cellular Gateway.
Solution 3
If you cannot find cellular reception anywhere at your site, you may not have carrier coverage
at your site. Contact Syncta’s Customer Support team at 888-725-4285 for more information.
POWER LED is Off
If the POWER LED is off, make sure the Cellular Gateway is plugged in and that the power
outlet is active. If the device is still not working, review the possible cause and solution below.
Possible Cause
If the Cellular Gateway is plugged in and the POWER LED is off, the +12Vdc & GND wiring
inside the Cellular Gateway might have been accidentally swapped.
Solution
Use the instructions on the next several pages to swap the +12Vdc and GND wiring inside the
Cellular Gateway.

Ensure that you unplug power to the Cellular Gateway before making any wiring
changes inside the device. Failure to do so may result in electrocution, personal injury,
and / or death.
WARNING
!
Troubleshooting (continued)
1. Unplug the power cord connected to the Cellular Gateway.
2. Using a #2 Phillips head screwdriver, remove the four screws that secure the cover of the
Cellular Gateway; set them aside.
3. Carefully remove the cover and place it aside.
10 UserGuide-SentryPlusAlert 2007 © 2020 Watts
Troubleshooting (continued)
4. Using a small flathead screwdriver, loosen the two bottom screws that connect the GND
and +12Vdc wiring to the terminals.
5. Once the screws are loose enough, carefully remove the wires by gently pulling them away
from the terminals; note which wire went into which terminal and reverse them.
6. Carefully insert the reversed wires into the terminals; you might need to hold the wires in
place and tighten the screws at the same time.
