From the wall control there are 2 wires. One with a red stripe goes to terminal #1. One solid white goes to terminal #2. From the door sensors the solid white wires go to terminal #2 and the 2 wires with black stripes go to terminal #3.

Safety reversing sensors wire open (broken or disconnected).

Each sensor has a solid white wire and a white wire with black tracer.

The solid white wires go to terminal 2 and the wires with the black tracer go to terminal 3.
