INSTALLATION To prevent SERIOUS INJURY or DEATH from a moving gate: • ALL gate operator systems REQUIRE two independent entrapment protection systems for each entrapment zone. • Entrapment protection devices MUST be installed to protect anyone who may come near a moving gate. • Entrapment protection devices MUST be located to protect in BOTH the open and close gate cycles. • Locate entrapment protection devices to protect between moving gate and RIGID objects, such as posts, walls, pillars, columns, or operator itself. Step 6 Install Entrapment Protection Install entrapment protection devices according to the UL 325 Entrapment Protection Requirements section, see page 3. Use the Site Planning Safety Checklist in the appendix, to identify entrapment zones that will result from the installation. 1. Install entrapment protection devices for ALL entrapment zones. This operator has an inherent entrapment protection device built-in. The installer MUST provide one additional entrapment protection device for each entrapment zone. 2. The operator will NOT run unless a minimum of one external device is connected 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. 3. Test ALL entrapment protection devices AFTER installing the operator, refer to the manual provided with your entrapment protection device. Illustration is for example only; your site may have additional entrapment zones which MUST be protected. 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 in) and less than 406 mm (16 in); 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 in). Any other gap between a moving gate and fixed counter opposing edges or surfaces or other fixed objects is less than 406 mm (16 in) (examples are walls, curbs, berms or other immovable objects). See Accessories for approved entrapment protection devices.
