Minimum of 8 which are already prewired thanks

Hi I have a Guardtech D500 system installed in my home an it incorporates shockguard sensors etc. I have just had new double glazing fitted and some of the sensors have been damaged, I would therefore like to upgrade my system with a new one as the wiring is already in place for the sensors I would like a wired and wireless system to increase security, I have been looking at the 595 or 816 and have spected out as system below can anyone tell me if this would work and if i have missed anything out? Guredtec 595 or (816 which has 16 zones, can I use each zone for each shockguard window sensor is this correct) 2 x wired surface mount magnetic door sensor for replacement (brown) 1 x wireless surface mount door sensor (white) new addition for conservatory 1 x new Battery 1 x Wireless hybrid card 2 wireless PIR
