How can I be sure that the gates are securely closed to keep unwelcome visitors out and my children and dogs in?

Each gate motor control has the option of operating the gate motors in one of two ways: – Full Automatic mode where a press of the transmitter button will open the gate and hold it open for a predetermined time (adjustable to between five 90 seconds) and then close it automatically. This way no one needs to remember to shut the gate. Semi Automatic mode where one press of the button will open the gate as before, but it won’t close automatically until the button is pressed again.
