Repeat the following for each IR sensor:

1. Reconnect the cable to one of the two IR sensors. Verify:

  • The Nano-controller “IN” and “OUT” LEDs on one of the Channels illuminates
  • The SC-770 controller indicates “OCCUPIED"

2. Close the cabinet door and stand clear of the occupancy sensors to clear the occupancy.

3. Quickly reopen the cabinet door and look at the SC-770 controller display. You should see the controller display change from “OK” to “OCCUPIED”
