According to the manual the two terminals to which you connect Garadget are:
- 0V (Input) is a 0 volt connection for Safety Beam, external receiver, osc, aux etc.
- O/S/C is used for the connection of a wired switch (momentary contact). This switch can then be used to open, stop or close the door. Install the wall switch in a location where the switch is out of reach of children and the garage door is visible.
