Troubleshooting 
If you are unable to get an IP address in step 3, then your router may not be configured for 
automatic DHCP or certain security settings may be enabled.  
•  Check your router settings and try again. 
•  On an NXX-1820- touchscreen keypad press Menu – [PIN] – [ENTER] – Installer – 
Communicator – IP Configuration – IP Options. “Enable DHCP” should be ticked, 
"Disable Web Pages on LAN” should be unticked. 
Check LAN Connection to UltraSync 
UltraSync is a cloud-based service that allows remote management and remote access to a 
Aritech Reliance XR system if enabled. This includes secure connections between the 
UltraSync+ app and Aritech Reliance XR. No programming, email addresses, panel 
usernames, or PIN codes are stored on the cloud servers for greater security. 
It features full redundancy to route encrypted alarm messages from your panel to a Central 
Monitoring Station.
