i came across this thread while looking for a solution for a similar problem i ran into. for the life of me i couldnt figure out why the gate i was using in my scratch build Kiss was working the exact opposite as it should. I finally figured out that the coil bracket actually has two sets of screw holes. if you use the lower holes the gate will open when energized. If you loose the top holes the gate energize when closed. hopefully this little bit of knowledge may help someone in the future.
