The design consists of a base plate onto which the door closer and a magnet are screwed. A closing arm with a magnetic arm and magnetic disk is mounted on the door closer. When the door is opened, the magnetic arm rotates with the magnetic disk until it strikes the electric holding magnet. If the electric-magnet is live, the door closer is held in place thus enabling the free-wheeling. In the event of an alarm, the power supply to the electric holding magnet is stopped and the door closer turns back and closes the door. The required door opening angle is adjusted with the coupling on the magnetic arm.
1. Tensioning
When the door is first opened, the door closer is tensioned (rotated) until the magnetic arm strikes the holding magnet.
2. Freilauf
Der Elektro-Haftmagnet ist eingeschaltet und hält den Türschliesser fest (Freilauf eingeschaltet). Die Türe ist frei beweglich.
3. Alarm
The electric holding magnet is dead when the alarm goes off. The magnetic arm rotates and closes the door securely.
