I am trying to set up my SWITCHSPOT sensor as an out for my driveway alarm receiver. Where do the red and black wires need  to be? My options are NC, NO, and COMM.

You have two options, you can choose to put them in either NC and COM or NO and COM. Polarity does not matter.

If you choose NC and COM that’s a “Closed” connection that opens on alarm, so you’ll want to set your Notification to be to notify on “Loop Open”.

If you choose NO and COM that’s an “Open” connection that closes on alarm, so you’ll want to set your Notification to be to notify on”Loop Closed”.
