UL 325 addresses gate operators and their safety functions. Owners should also ask how the equipment, protective devices and gate construction fit the site.

A gate’s safety depends on the equipment, the installation and how people use the entrance. Owners should know what to watch for and when to stop using it.

Start with the entrance and how it is used. Gate movement, traffic and site conditions give an installer the information needed to recommend an operator.

A gate that stays open may be following a command or responding to a fault. The movement sequence gives the service technician a better starting point.

A gate that won’t open can have a power, access-control or mechanical problem. What happens when you request entry helps narrow down the next step.
