Features:

• Free-swing arm assembly only, suits Dorma TS 73 EMF.
• Used where doors are required to operate normally - functioning in the same way as doors without a door closer.
• If the door leaf is opened wide (min. 75°), the closer spindle is held in this position by the electromagnetic hold-open device in the hydraulic closer body.
  However, the door can be freely operated by virtue of the free-swing function integrated in the arm.
• In the event of a fire or power failure, the door is reliably and securely closed automatically by the hydraulic door closer.
• Typical applications include fire and smoke check doors in senior citizen homes, homes for the disabled and hospitals etc.

Note: In the case of double doors, the free-swing function may only be used on the active leaf.
