if you have an additional 2 circuits where the 6 core goes back to (im assuming panel) then just use a pair for each contact (ie red/blk contact 1, blu/yell contact2 etc) and program the panel to the correct eol values.
Wiring should be in the manual but if not just say and ill dig out an image.
But also bear in mind how the contacts are installed. If there is an issue there however you wire them you will have problems.
Post a picture of the 3 with the door closed please
