Be the first to review this product

Dorma ED900-J8-SW with an innovative electromechanical drive and state-of-the-art microprocessor motion control system, the 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. 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. The ED900 also includes a blow-open feature for smoke ventilation (per NFPA 92B), permanent hold-open, and an onboard power supply delivering 1.5 amps @ 24 VDC, which eliminates the need for a secondary power supply. It includes 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.
