Simplex 4901-9820 TrueAlert Remote Horn
This is the remote horn variant of the original Simplex TrueAlert series. This one was brand new in box, operates on 24VDC, and is extremely loud. Selectable Free-Run or Smart-Sync modes. I have another one of these horns that is used, and that device will likely be featured in my next system test.
