Scantronic 9100 keypad wiring

[Guest Hyrava]

Does anybody know detailed specification of Scantronic 9100 keypad wiring?

My problem is, that I'm replacing good old Scantronics 9100 stuff with DSC stuff, and some previous installers used ALL wires at cable (MHS 5x2+1+1x0,5). Keypad uses 5 pairs and some of them were wired even 2 PIR detectors to same cable.

So my question is, which keypad wire can be used as COM wire for detectors? or even better, if I could have data for each of keypad's 10 wires...

Sorry my bad english, but I live in Finland.

Thanks in advance...
