How to Install a Safety Loop on a DoorKing Gate Operator

DoorKing manufactures security devices for homes and businesses including telephone entry, parking control and gate operators. The gate operator device prevents unauthorized access to a building. It is configured to allow you to add safety loop wiring, available from DoorKing, to detect when a vehicle is within the vicinity of the gate. This prevents the gate from accidentally closing on a vehicle, person or object.
