Any information on an Ademco vista 20?

I’ve been wanting to find information on the vista 20 about programing. Been thinking of reactivating it. Many of the old wireless sensors don’t work/removed after renovations. What newer products are backwards compatible with the system and how would I program they? The only information I have for it is the user manual.

Is this what you need Honeywell Vista-15P/Vista-20P - Program Guide - Dated 3/15 Rev. B - Alarm Grid
