Hi, on my new Pro board I have 1 siren attached to each of the two connectors as outlined in the configuration documentation. Both are configured the same other than the name (1=Inside / 2=Outside)
My testing shows that only siren ONE works fine, and the red LED on the board illuminates; siren TWO does nothing. No power, no led.
Thank you, Nate. I am finally hooking up the wires for my alarm as the last step in my config. That did the trick - both sirens work fine now. I appreciate the quick response.
