Zone question

Hi, I would like to install the Konnected Interface in parallel with my DSC 832 security system.  The system has 3 keypads and 27 zones, each of the zones show individual activity on the keypad.  When I look at the alarm panel I can see wiring for zones 1 thru 8 (attached is a pic) connected to the circuit board, there are no extension modules to be found in the alarm box - I've searched the house up and down and do not see any other alarm boxes.  Does anyone have suggestions on how to proceed with having the Konnected system work with all 27 zones?  

I found an extension module buried in the wall behind one of my keypads. You might try unscrewing it and having a look…
