The driveway exit sensor is a magnetic device that installs below ground beside the drive. A magnetic field is established which when interrupted by a metal object will send a signal to open the gate. This sensor is supplied with a 100 ft cable and is typically installed inside the property beside the drive to automatically open the gate when a car passes.
If more cable is desired do not attempt to add cable as this will only create problems.
This type of sensor is not a safety device, it is recommended to install this sensor and cable in PVC conduit.
