I have a quick question on the use of a System Sensor MDL3R connected to the Remote Sync output on a FireLite panel, would that work as long as the panel is set to System Sensor Sync? I guess I am not quite sure on how that would play out, or if that would even work? I currently have a FireLite ES-50X and I understand they have System Sensor sync built in. But I am more saying if the notification appliance(s) were powered off a control module, that is where it would make the most sense. Because I do have a MDL3R sync module that I have had a couple of years, and it is best if I have this information now so if I ever do expand my new system to like a little shed or something, I would like that to have it’s own NAC and be synced with the rest of the system so it doesn’t sound so weird.
There is a Remote Power Supply Sync. output set of terminals on the ES-50X, It is meant for NAC Boosters, but try using that as your MDL3R Remote Sync, and see if it works.
