What is an underground exit loop?

An exit loop is a loop of wire placed under the driveway and connected to a loop detector in the gates' control box. When a vehicle drives over the loop, it is sensed by the detector which then opens the gate automatically. This obviates the need for you seeing visitors off the premises.

I need the gate to open 180 degrees so I can pull into my garage / space at the side.

Two solutions here: either purchase a GateMotors Blank underground motor kit with a 180-degree adaptor (this will need your gate mounted on the rear of the pillars so that each gate can hinge all the way back); or get your blacksmith to weld the leading edges of your gates swing gates (or get him to fabricate a single gate that has the appearance of a pair of swing gates) and purchase a GateMotors Roller sliding gate kit.

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.
