Help with older vista setup

I have 3 5881en recievers, and just replaced an old vista 20se with an equally old 20p :slight_smile:
Anyhow, my relievers show a green light constantly, and do not update when any door is opened. Do I need to reprogram the recievers? Any guidance would be much appreciated.

If swapping a panel you’ll need to enroll the wireless devices again as the new panel would not have the wireless zones enrolled. Enter installer programming and *56 for wireless zone programming, starting at your first unused zone.
