dormakaba’s most advanced low-energy swing door power operator

Employing an innovative electromechanical drive and a 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.

Advanced power assist

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 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.

Small footprint

In addition, the ED900 low energy operator boasts the smallest footprint in the industry, up to 65 percent smaller than some other manufacturers’ operators.

Onboard Power Supply

Delivers an unprecedented 1.5 amps @ 24 VDC: 3× more power than the competition. No need for separate power supply.
