9| Programming & Wireless Check-In
9.1 – Property Setup
The NextCentury 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.
9.2 – 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.
9.3 – Gateway Device Management
After programming, the connected Gateway will automatically
sync and communicate with the LS4.
9.4 – 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
9.5 – 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
Repeater may be needed
