The replacement receiver is somewhat configured different from the older version,
As I have two working receivers switching relays, on an outside PE Beams. every 10 or so on - off from new and older tranmitters, , the new relay button 3, stops working. only older receiver switch's, need to push button 3 on- off 2 -3 times than comes good for the next 10 or so On - off. other than that, good, I have been using the NX panels and receivers long before the re naming. I have work in the Electrical and security for over 40 years. from the old days when keys and toggles operated alarm panel.
