UL 325 is the Underwriters Laboratories (UL) standard for Door and Gate Operators, as well as other products.
Since 2010 all commercial door operators bearing the UL Label must continuously monitor safety devices such as photo eyes and/or sensing edges, otherwise the operator must be limited to constant-pressure-to-close operation.
Since 2000, external entrapment protection devices must be added to gate operators to meet these standards. Gate operator designs will be additionally required to continuously monitor entrapment protection devices by January 2016.
