INTRODUCTION Site Preparation Check the national and local building codes BEFORE installation. Refer also to the Site Planning Safety Checklist in the Appendix. Conduit and Concrete Pad Trench and install conduit. Before trenching, contact underground utility locating companies. Conduit must be UL approved for low and high voltage. Consider the operator placement BEFORE installing the pad or post. Safety Entrapment protection devices are required to protect against any entrapment or safety conditions encountered in your gate application. Install a warning sign (two provided) on the inside and outside of the property, where easily visible. Warning Sign Concrete Pads Gate Gate must be constructed and installed according to ASTM F2200 standards (refer to page 4). Gate must fit specifications of operator (refer to specifications). Additional Accessories The vehicle loops allow the gate to stay open when vehicles are obstructing the gate path. Suggested for vehicles 14 feet (4.27 m) or longer. Vehicle loops are not required but are recommended. Before installing your Access Control Device(s) be sure to complete a site survey and determine the best device for your site needs. Access Control Device Vehicle Loops Outside Property SAFETY CATCH ROLLERS Install catch rollers with safety covers on the side of a post or wall with a minimal distance of half an inch between the rollers and gate DO NOT use a gate catch post. Because the coasting distance may vary due to changes in temperature, it is NOT recommended to install a catch post in front of the gate's path. To do so will cause the gate to hit the post in certain instances. 8
