The UL-325 standard that addresses the automatic operation of garage doors, Drapery, Gate, Louver and Window Operators and Systems also contains provisions related to the automatic operation of access control gates. The primary intent of the standards is to prevent entrapment of persons in automated gate systems, as well as preventing injuries from pinch points. UL 325 is not concerned about the gate contacting vehicles, only the entrapment of people.
