32  Installation and Programming Guide 
Getting Connected 
Once your devices have been cabled and installed, there are four (4) ways to connect to the 
Aritech Reliance XR system to perform programming: 
 
Method 1: via UltraSync+ app – this provides access to the built-in Web Server 
via a smartphone app. 
 
 
Method 2: via built-in Web Server – All features can be accessed from a web 
browser via drop-down and click-through menus. No software installation is 
required. This allows access to most accessed features for basic programming. 
 
Method 3: via DLX900 Management Software – All features can be 
programmed using a PC with Microsoft Windows 7, 8 and 10. DLX900 allows 
easier programming of complex sites as the graphical interface can show all 
options from multiple menus simultaneously. 
 
Method 4: via on-site keypad - The NXX-1820- touchscreen offers a 
programming menu for full system configuration. Refer to the NXX-1820- 
Installation Manual. The Aritech Reliance XR Reference Guide will assist you in 
navigating the menus. 
 
Account Access 
Note: Installer Account Disabled When Armed 
If a non-engineer account arms the system at any time, engineer accounts will not be able 
to log in, any current program mode will end, and this will be recorded in the event log. Ask 
the end-user to disarm the panel and leave it disarmed so you can log in to program it. 
Note: Remote Access May Require Level 2 User Authorization 
Two remote access features “Enable Web Program” and “Always Allow DLX900” require an 
authorized master (Level 2) user to enter their PIN code on an NXX-1820- keypad before 
remote programming can be performed.  
If either “Enable Web Program” or “Always Allow DLX900” have been disabled, ask a 
Master User to press Menu, enter their PIN code on a keypad, then Settings. The panel will 
now be in Program Mode, and you can use an engineer (Level 3) user such as “installer” to 
perform programming via the web page, app, or DLX900.
