Our Texecom 64-W install is complete and functioning, so thanks to all here who provided advice. I'd like to know how, if indeed it's possible, I can program the system to allow the part-arm to activate with the single press of a button. At present we have to enter user code, press the part-arm key, press ‘1’ key, and press tick on the keypad. This is a bit of a hassle when we're going to bed!
