I remember seeing a topic a while ago where someone was asking about using the existing garage door "electric eye" as an input to a zone on the Elk or for the matter, any automation system. Since the output of the receiver side of the photodetector is NOT a dry contact, this would not work directly. However...
What if you wired in something like the Elk-930 doorbell ( and telephone) ring detector? I don't know how much current the garage door's photodetector draws, but if it exceeds the threshold needed by the 930 would this work? If not, is there another way to do this?
