For fire protection: with doors that should be freely moveable but must close automatically in the event of a fire.
The free-wheel basic version F-T46/50 but the door is closed by a slide rail instead of a standarm. The FG-T46/50 is also available in a version for counter-hinge-side head installation.
- No electrical connection cable (wall mounted door closer)
- The use of a standard door closer
- No slipping or creeping shut of the door, no springback (pressure build-up)
- Minimal maintenance and long life guarantee high efficiency
- Breaker button on the magnetic latch
- Easy installation and guaranteed purchase by competent authorities
Use: Hospitals, nursing homes, homes for the disabled and RDA systems, which have to guarantee a secure closure at 50 Pa positive pressure (FG-T50B, FG-T50G).
The design consists of a base plate onto which the door closer and a magnet are screwed. A closing arm with a magnetic arm is mounted on the door closer. When the door is opened, the magnetic arm rotates until it strikes the electric holding magnet. If the electric holding 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 (max. setting 135°).
1. Tensioning
When the door is first opened, the door closer is tensioned (rotated) until the magnetic arm strikes the holding magnet.
2. Free-wheel
The electric holding magnet is turned on and holds the door closer (enabling the free-wheeling). The door is freely moveable.
3. Alarm
The electric holding magnet is dead when the alarm goes off. The magnetic arm rotates and closes the door securely.
