Hello all, I have a PCCS9RW and am getting a WSSC30. I have my PCCS set up to go through siren tones and use the horn. Please reference pic #1. I noticed that the PCCS's outputs from the J# outputs on the back are actually in (+), but the siren switches its tones and toggles the horn by using a (-) switch. Is there a way I can still use my PCCS to switch tones somehow? See picture #2 to see what I am talking about.
