UL325 MODEL CLASSIFICATIONS CLASS I - RESIDENTIAL VEHICULAR GATE OPERATOR A vehicular gate operator (or system) intended for use in a home of one-to four single family dwellings, or a garage or parking area associated therewith. CLASS II - COMMERCIAL/GENERAL ACCESS VEHICULAR GATE OPERATOR A vehicular gate operator (or system) intended for use in a commercial location or building such as a multi-family housing unit (five or more single family units) hotel, garage, retail store or other building servicing the general public. CLASS III - INDUSTRIAL/LIMITED ACCESS VEHICULAR GATE OPERATOR A vehicular gate operator (or system) intended for use in a industrial location or building such as a factory or loading dock area or other location not intended to service the general public. CLASS IV - RESTRICTED ACCESS VEHICULAR GATE OPERATOR A vehicular gate operator (or system) intended for use in a guarded industrial location or building such as an airport security area or other restricted access locations not servicing the general public, in which unauthorized access is prevented via supervision by security personnel. 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, self-contained within the operator. This system must sense and initiate the reverse of the gate within two seconds of contact with a solid object. Type B1: Connections provided for a non-contact device, such as a photoelectric eye can be used as a secondary protection. 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 open and close. Type E: Built-in audio alarm. Examples include sirens, horns or buzzers. NOTE: UL requires that all installations must have warning signs placed in plain view on both sides of the gate to warn pedestrians of the dangers of motorized gate systems. Moving Gate Can Cause Injury or Death KEEP CLEAR! Gate may move at any time without prior warning. Do not let children operate the gate or play in the gate area. This entrance is for vehicles onl.y Pedestrians must use separate entrance UL325 ENTRAPMENT PROTECTION REQUIREMENTS GATE OPERATOR ENTRAPMENT PROTECTION UL325 Installation Class Class I & II Slide Gate Operator Primary Type A Secondary Type B1, B2 or D Swing & Gate Barrier (Arm) Operator Primary Type Secondary Type A or C A, B1, B2, or C Class III A, B1 or B2 A, B1, B2, A, B1, B2 A, B1, B2, D or E or C C, D or E Class IV A, B1, B2 or D A, B1, B2, A, B1, B2, A, B1, B2, D or E C or D C, D or E 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 single-family residence (UL325 Class I) you must provide the following: As your primary type of entrapment protection you must provide Type A inherent (built into the operator) entrapment sensing and at least one of the following as your secondary entrapment protection: Type B1- Non-contact sensors such as photoelectric eyes, Type B2- Contact sensors such as gate edges or Type D- Constant pressure control. 4
