Adding zone / device with the connected module?

Hi, first i want to keep my existing setup, keyboard and panel.  I have a DSC 1832 with RFK5500 keypad.

I would like to use my water sensor into the alarm ?  Or be notified in case of leak ?  

I also want to add 2 wireless motion detection on my alarm system.  Can i add it with Konnected or i need to stay with DSC ?

Will the Konnected Alarm Panel Pro 12-Zone will change something ?  as far as i understand the connected module is the main ''brain" the alarm panel from konnected is there but 'idle'


Yes or no ? Is it possible
