DORMA’s innovative, whisper quiet low energy operator with electromechanical drive and advanced power assist Innovative Technology Employing an innovative electromechanical drive and a state-of-the-art microprocessor motion control system, the new ED900 is DORMA's most advanced low-energy swing door power operator. The operator is exceptionally quiet, safe, and easy to use. When operated manually, the ED900 demands little physical effort. Advanced power assist through the entire opening cycle makes even the heaviest-rated door feel light. Fully ADA Compliant The new operator is especially helpful for children, the elderly, persons with disabilities, or those carrying objects or pushing carts. This fully ADA-compliant device opens doors at precisely controlled speeds and forces, assuring safety for all users. Advanced Features The ED900 also includes a blow-open feature for smoke ventilation (per NFPA code 92B), permanent hold-open, and an onboard power supply delivering 1.5 amps @ 24-volt DC, which eliminates the need for a secondary power supply. It includes twelve programmable options to accommodate even the most challenging door installations. In addition, the ED900 boasts the smallest footprint in the industry—up to 65 percent smaller than some other manufacturers' operators.
