Hello. I ask here on behalf. A large building was equipped with several ZoneFlex 7372 just a few years ago. Now another floor is to be equipped with it (perhaps 3-5 transmitters) and integrated into the system. Now I have noticed that the ZoneFlex 7372 is no longer available. My question is, is there a successor to the ZoneFlex 7372? With which one can extend the existing plant? I would be very happy about a tip.
