Usage Class Class I - Residential Vehicular Gate Operator A vehicular gate operator (or system) intended for use in garages or parking areas associated with a residence of one-to four single families. Class II - Commercial/General Access Vehicular Gate 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, garages, retail store, or other buildings accessible by or servicing the general public. Class III - Industrial/Limited Access Vehicular Gate A vehicular gate operator (or system) intended for use in an industrial location or building such as a factory or loading dock area or other locations not accessible by or 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. UL325 Entrapment Protection Requirements Definitions ENTRAPMENT: The condition when a person is caught or held in a position that increases the risk of injury. SWING GATE ENTRAPMENT ZONE: Locations between a moving gate or moving, exposed operator components and a counter opposing edge or surface where entrapment is possible up to 1.8 m (6 ft.) above grade. Such locations occur if during any point in travel: a. The gap between the bottom of a moving gate and the ground is greater than 101.6 mm (4") and less than 406 mm (16"); or b. The distance between the center line of the pivot and the end of the wall, pillar, or column to which it is mounted when in the open or closed position exceeds 101.6 mm (4"). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16") (examples are walls, curbs, berms or other immovable objects). INDEPENDENT MONITORED ENTRAPMENT PROTECTION DEVICE: An entrapment protection device is independent if it is a different type (photoelectric sensors, edge device, inherent protection device) from the other devices in the same entrapment zone. Use the Site Planning Safety Checklist in the appendix to identify entrapment zones found in your installation. Requirements • A minimum of two independent monitored entrapment protection devices are required to be installed at each entrapment zone. • It is the responsibility of the installer to install external monitored entrapment protection devices for each entrapment zone. • The operator will only operate with a minimum of two independent monitored entrapment protection devices installed in either the open or closed direction. If no entrapment zone exists in the other direction, an external entrapment protection device is NOT required in that direction. This operator has an inherent entrapment protection device built-in. The installer MUST provide one additional entrapment protection device for each entrapment zone. Acceptable entrapment protection device types include: • Inherent (built into the operator) • LiftMaster monitored external photoelectric sensors, see page 52 for acceptable sensors. • LiftMaster monitored external edge sensors, see page 52 for acceptable sensors. IMPORTANT SAFETY INSTRUCTIONS To reduce the risk of INJURY or DEATH: • READ AND FOLLOW ALL INSTRUCTIONS. • NEVER let children operate or play with gate controls. Keep the remote control away from children. • ALWAYS keep people and objects away from the gate. NO ONE SHOULD CROSS THE PATH OF THE MOVING GATE. • Test the gate operator monthly. The gate MUST reverse on contact with an object or reverse when an object activates the noncontact sensors. After adjusting the speed, force, or the limit of travel, retest the gate operator. Failure to adjust and retest the gate operator properly can increase the risk of INJURY or DEATH. • Use the manual release ONLY when the gate is not moving. • KEEP GATES PROPERLY MAINTAINED. Read this manual. Have a Trained Gate Systems Technician make repairs to gate hardware. • The entrance is for vehicles ONLY. Pedestrians MUST use separate entrance. • SAVE THESE INSTRUCTIONS. 3
