How to switch to suretyDIY with a Simon XTi

I am purchasing a home with a Simon XTI security system. The owner has no information on it, how to reprogram it, or how it’s monitored. I see on a UTube video you monitor them. How do I get it started with my codes and information. What all features does the system have?
