I have started to install on a dsc1832, keeping the old system intact. I see 8 zones on the dsc panel, but I have 9 zones active on my keypad! On my dsc panel I have:
1 Door 1
2 Door 2
3 Window 1
4 Window 2
5 Window 3
9: Door 3 <--This is the one I cannot locate ...
Where is the 9th zone for me to plug the konnected line into? This 9th door is working and chimes when I open and close, but I can't figure out which wires are for this door. There is no expander card, Just a basic dsc 1832 card with the 8 zones. Is this a weird way it was programmed by the original installer?
