41 Barbara Kelkhoff, Chamberlain Group and Maria Iafano, Underwriters Laboratories TECHNICAL The Door & Access Systems Manufacturers Association (DASMA) and the Canadian Door Institute of Dealers, Manufacturers and Distributors (CDI) recently worked with the Underwriters Laboratories, Inc. (UL) 325 Standards Technical Panel to successfully publish ANSI/CAN/UL 325, Standard for Safety for Door, Drapery, Gate, Louver and Window Operators and Systems as a Joint Canada-United States National Standard in May 2017. The cooperation between U.S. and Canadian manufacturers and industry partners was essential to technically align door and gate operator requirements across Canada and the U.S. – bringing these industries back into alignment for the first time since the mid-1990s. This harmonized standard aids in providing consistency and the latest in safety requirements for the door and gate operator industry and facilitates the same products being purchased and used in both countries. WHAT DOES ANSI/CAN/UL 325 MEAN FOR YOU? ANSI/CAN/UL 325 was published as a joint bi-national standard. It is the National Standard of Canada - approved by the Standards Council of Canada (SCC) - in addition to being an American National Standard - approved by the American National Standards Institute (ANSI). It outlines the minimum product safety, manufacturing and installation requirements for commercial and residential door and gate operators and similar products. Now that ANSI/CAN/UL 325 has been published as a bi-national standard, those within the industry can expect demand for compliance to ANSI/ CAN/UL 325 to increase. While there were many differences between both country's standards, it is important to note a few key changes that may affect manufacturers, operators and installers: RESIDENTIAL DOOR OPERATORS Accessories able to control residential doors by timers, remote phone apps or similar devices have additional control function requirements as well as new alert requirements before motion can occur. Entrapment protection systems shall be designed to ensure the operator continues to reverse within 2 seconds, even when the door motion begins within 2 inches of an obstruction. VEHICULAR GATE OPERATORS Two independent entrapment protection devices must be installed and active to protect each entrapment zone of an automated vehicular gate system. Operator shall not operate until after the minimum number of entrapment protection devices is installed Operators must continuously monitor for the proper operation of any external entrapment protection devices like a photoelectric system or sensing edges. If the external entrapment protection device is not working, the operator shall be designed to limit control functions to close (or open) the gate only under a constant-pressure mode. It shall not be easy to bypass, interfere with or defeat the monitoring system. COMMERCIAL DOOR OPERATORS Similar to the current standards, an external entrapment protection device, such as a photoelectric system or sensing edge, must be installed protecting the entrapment zone at the floor for any door that can be closed by any controls other than constant pressure (e.g. remote control, timer, loop sensor). Operators must continuously monitor the proper operation of any external entrapment protection devices like a photoelectric system or sensing edge. If the external entrapment protection device is not working, the operator shall be designed to limit control functions to constant-pressure-to-close operation. It is important to be sure your door and gate operators comply with the new ASNI/CAN/UL 325. New, harmonized Canada-U.S. door & operator standard in 2018.
