Hi, I don't have much knowledge about electronics but I have bought a remote switch using which one can remotely (100 meter distance) turn on/off a light or any other appliance. There is a two buttons "bpt" intercom in my unit. I want to use this remote switch with that intercom such that pressing the remote button automatically works like pressing the intercom button and door can easily be unlocked from outside even if no one is home. I know we have to give voltage +/- on inputs but I am not sure how will I be using NO and NC ports of receiver circuit of remote switch to make that intercom button work without physically pressing it. I am attaching a photo also. I would really appreciate if someone helps me with this. Thanks in advance.
