Programming & Wireless Check-In

Property Setup
The next century website or NCSS mobile app can be used to set up and configure the property, units, and meters. Visit support.nextcenturymeters.com for additional property setup details.

Programming
Property programming is the process of associating Leak Sensor serial numbers to the meters they are reading. Scan the barcode to ensure the serial number is entered accurately.

Gateway Device Management
After programming, the connected Gateway will automatically sync and communicate with the LS4.

Wireless Connection LED Indicators
The RF LED indicator provides feedback to easily check that the LS4 is within range of the property’s Gateway (either directly, or through Repeaters)

Tap the Test Connect button
The LS4 RF LED will rapidly blink red, indicating it is transmitting
The RF LED will then blink 2x green if a response is received from the Gateway

Wireless Troubleshooting
If the RF LED does not blink green after tapping the Test Connect button, then the LS4 is not receiving a response from the Gateway. The following steps can help identify the issue:

If the LS4 does not blink green, even when close to the Gateway, make sure it has been programmed to the property and the Gateway is online
Try multiple times—if eventually a response is received, then an additional Repeater may be needed to improve the wireless network
Move the LS4 closer to the Gateway or nearest Repeater. If a response is received, then an additional A repeater may be needed
