INTRODUCTION SITE PREPARATION Check the national and local building codes BEFORE installation. CONDUIT & CONCRETE PAD 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 warning signs on both sides of the gate. Warning Signs 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). VEHICLE LOOPS 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. SAFETY CATCH ROLLERS DO NOT use a gate catch post. 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. Because the coasting distance may vary due to changes in temperature, it is NOT recommended to install a stop or catch post in front of the gate's path. To do so will cause the gate to hit the post in certain instances. 7 (Inside Property)
