Also, if you can make pictures of the important parts available - PDB, DSC, Spike - while in operation (aka LED's on the DSC lighting up when it should be triggered), it could help diagnose. Ensure you have things properly labeled, so we know where the power from the PDB is coming from, which side of the Spike it's going into (double check this, don't assume!), which port each spike is connected to, etc. Something could jump out at us that we wouldn't think to tell you just from a problem description.
