As some of you already know, I bought a Simplex 4903-9416 (Two-wire SmartSync A/V signal). However, I would like to know If there are any SmartSync Modules out there that would work with this model when put on a conventional NAC. I’ve been looking at the 4905-9938, but I’m not sure if its compatible with this model.
From what I know, the -9938 will work with the 4903 and 4904 series. It is basically designed for non-SmartSync NACs. Refer to this PDF for compatibility on devices: https://simplex-fire.com/en/us/DocumentsandMedia/4905-0003.PDF
