dormakaba Free Swing Arm

Free swing arm for use with the TS 73 EMF can also be employed 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 electro-magnetic 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.
