We have a puzzlement and need some help. We want to have interlocking (right word?) signals between the upper and lower levels. Please take a look at the attached picture.
On the DZ 1050 signal on the lower left corner, the 1008 is wired into a DZ 1000 with the R,G, and Y all going to the AIU. Black and blue wires from 1008 are to power and common. Gray and white ones are wired to the DZ 1050 for NO/NC. The red and black are to power and common on the DZ1050. Based on the picture below, is it possible to wire a second 1050 (located at the white circle) using the same 1008, but reversing the NO/NC?
Or do we need a DP/ST and, if so, how should that be wired so that when the switch is thrown the lights change accordingly?
