A Step-By-Step Guide to Choosing Gate Operators
Selecting the right gate operator for your customer can be an involved project. Mark Mattson, Linear® Access Control product manager at Nortek Control, has developed a series of questions, answers and useful tips to help fencing professionals guide their customers. Mattson has nearly two decades of experience in the access industry and has worked in several roles from operations to marketing to engineering under the Linear access control brand. “As you know, there are multiple factors to consider when selecting the best operator to meet the customer’s requirements. To help sort this out, we’ve compiled a list of the important questions to answer that will help direct you and your customer to the best solution,” Mattson says. He recommends the following questions: What type of gate will the operator be used for? “Ensure that it is only intended for vehicular use as gate operators are not recommended for pedestrian use as serious injuries to people can result from many situations that arise within the surrounding area of a moving gate,” he explains. “A good thing to consider in the decision is that UL 325 regulations have the requirement that pedestrians must not use an opening which is automated for vehicular use.”
For a slide gate, is it cantilever, overhead, v-groove track, roller or enclosed track gate? For a swing gate, what is the material used and how much of the gate area is covered? Will wind be a factor in the gate operator’s operation? Is the gate new or existing? If the installation is on an existing gate, it is recommended that the installer open and close it manually to ensure a smooth operation. “Remember, gate operators do not correct gate problems,” Mattson says. In addition, existing gates that are to be automated must meet the ASTM F-2200 standard for gate construction. Also, does the gate require roller covers? Are the pinch points protected? And, if it is a slide gate, does it include a screen to 2.25 inches? What is the length, height, and weight of the gate? Is there anything about its construction or installation that prevents it from moving freely or smoothly? Will the operator be subjected to prolong temperatures that are below freezing? If so, your customer may want to consider adding a heater or cold weather package.Is the installation a single gate or paired dual gate application? Some operators, such as the Linear APeX controller equipped operators enable two gates to be
networked together to work as a pair in a dual gate installation. Be sure your supplier includes shielded cabling in the quote, which is needed to support the networked application. Other operators, such as Linear’s PRO-SW series operators offer both arms to be driven by a single controller. How many cycles will the gate open and close per day? Gates that have a high-duty cycle require a heavy-duty gate operator system. “For high cycle gates positioned away from pedestrian locations, you should consider a variable speed operator; that is a much more efficient and cost-effective solution and one that offers the ability to smoothly move a large, heavy gate at considerably higher speeds,” explains Mattson. What voltage and phase are required for the gate to operate? This is generally dependent on what voltage is available at the site. “It is recommended to use the highest voltage available at the site along with 3-phase power if it is available,” Mattson says. How will the gate operator be physically installed? Some operators are designed to be pad mounted, and others post mounted. There is some flexibility in making this decision as many suppliers offer kits to post mount a pad mount operator and pad mount a post-mount operator. Continued on p44
