Use the Service Walk Test to test off-board points.

Refer to the D9412GV2/D7412GV2/D7212GV2

Installation and Troubleshooting Quick Reference

Guide (P/N: F01U003638) for instructions. Test to

ensure that all off-board points operate properly.

Extra Points: If the point assignment switches on a

POPIT or OctoPOPIT are set incorrectly, missing and

extra points can occur. If the same point number is

assigned to two or more POPITs or OctoPOPITs,

none of the points with that number test correctly.
