Magnet installation - Locking cylinder (Z4) DoorMonitoring

The sensor in the fastening screw works magnetically. Therefore you have to glue the magnetic plates, which are attached to the fastening screw, into the door frame. Then perform a function test.

One or more magnetic plates need to be glued on, depending on the door and frame material and the gap width

NOTE

notice

Overdrive of the sensor

If you mount too many plates, the magnetic field becomes too strong. The sensor in the fastening screw is then overridden and no longer responds.

NOTE

notice

Lack of adhesive strength due to unsuitable support surface

Dust, dirt and grease reduce the adhesive strength of the magnetic plate. The magnetic plate may fall down and cause malfunction.

  1. Make sure that the surface is clean and free of grease before applying magnetic plates.
  1. Glue the magnetic plates loosely into the door frame so that the plates are opposite the head of the fastening screw.
  2. Close the door carefully so that the latch almost clicks into place.
  3. If the display in the LSM jumps from "open" to "closed" when the door is almost closed:
    - Reduce the number of magnetic plates.
    - Move the plate further in the direction of the centre of the frame.
    - Reduce the size of the plate.
  4. Close the door.
  5. The indicator in LSM must change from 'open' to 'closed.' If this not the case, the magnetic field is too weak for the sensor. Stick an additional plate on the door frame and repeat the test.
