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.

Advanced Power Assist (Helping Force)

Works through entire opening cycle. When opened manually, even the heaviest rated door feels about 5 Ib.

Blow Open for integration into smoke ventilation systems per NFPA 92B. Permanent Hold Open triggered two ways: (1) by onboard toggle switch or (2) by input from a remote source.

Obstacle Detection closes the door if an obstacle is detected during the opening cycle and reopens the door if an obstacle is detected during the closing cycle.

Push & Go triggered by manually opening the door 4° from the closed position.

Onboard Power Supply delivers an unprecedented 1.5 amps @ 24 VDC

  • 3× more power than the competition.
  • No need for separate power supply.
  • Powers most EAC devices, including electromagnetic locks, electric strikes, RF transmitters/receivers, illuminated push buttons, wall switches, presence detectors, motion sensors, and key pads.

Motion and Presence Sensors can be installed on both push and pull side of the opening. Closing Speed and Latching Force under power failure conditions are field-adjustable as part of installation set-up and commissioning.

Positive Mechanical Stops with both Pull Side track mount and Push Side arms are included. In the event of power failure conditions, the stops prevent the door from opening past 90° or a pre-determined opening angle.
