SDC's Auto Entry-Control low-energy swing door operators are designed for applications requiring ADA compliance or user convenience. SDC’s operator is built with a state-of-the-art microprocessor-based unit that is self-tuning and self-learning while offering nonhanded operation, full-mechanical stops, and a variety of interface options for sensors, push-plates, fire alarms and electrified locks. SDC’s operator is belt driven with a combination of gears and pulleys which requires less torque, less power, absorbs more abuse, and is quieter than other automatic door openers while complying with all US and Canadian ADA requirements. Onboard diagnostics simplifies troubleshooting for ease of installation and all SDC operators can be easily configured for surface mounted push/pull applications. ANSI certified not required for initial installation.
