Ran across this thread because I'm interested in using the "Safe-T-Beam" LED/optical sensors that are already wired to my Genie 7055 garage door opener to enable a red/green "Blocked/Clear" light on my garage ceiling that would tell me if I've pulled in far enough to clear the sensors and hence the garage door. Would love to figure out where to tap into the controller's circuit board to intercept this signal and drive a ceiling indicator light without have to build a circuit that decodes the sensor's pulse train itself. Any hints on how to accomplish this? Anyone ever seen an actual schematic for this GDO controller board?
