After a bit on info... had a new door fitted and the part on the door has been skipped and I am left with the part of the contact with the wires connected ..now I cant set the alarm it has 3 screw terminals with wires attached ..on one screw is white and blue wires on another one is a green wire and another one has a yellow wire... in order to set the alarm do I just loop some of the wires together for now .. but instead of replacing a door contact I would like to move the cable up and change it to a PIR ... also if changing to a PIR what colours go where... thanks in advance
