Installation Manual WARNING When a VEHICLE SENSOR is in use, the automatic gate opener could be activated by a child on a bicycle, tricycle or other metal play equipment. This product is not recom- mended for applications exposed to children.
If a metal object is placed directly above the sensor (with little motion) it may cause the sensor to activate, thus opening your gate. For this reason we do not recommend the VEHICLE SENSOR in environments exposed to children.
