SAFETY ACCESSORY SELECTION
All UL325 compliant LiftMaster gate operators will accept external entrapment protection devices to protect people from motorized gate systems. UL325 requires that the type of entrapment protection correctly matches each gate application. Below are the six types of entrapment protection systems recognized by UL325 for use on this operator.
ENTRAPMENT PROTECTION TYPES
Type A: Inherent obstruction sensing system,
Type B1: Connections provided for a
Type B2: Connections provided for a contact sensor. A contact device such as a gate edge can be used for secondary protection.
Type C: Inherent adjustable clutch or pressure relief valve.
Type D: Connections provided for a control requiring continuous pressure to operate the operator

The chart above illustrates the entrapment protection requirements for each of the four UL325 classes.
In order to complete a proper installation you must satisfy the entrapment protection chart shown above. That means that the installation must have one primary means of entrapment protection and one independent secondary means of entrapment protection. Both primary and secondary entrapment protection methods must be designed, arranged or configured to protect against entrapments in both the open and close directions of gate travel.
For Example: For a slide gate system that is installed on a
