Functional test - MobileKey Locking cylinder (Z4)

  • To verify that the AP2 cylinder functions correctly in an anti-panic lock, you must check that the cam moves easily and that the door opens correctly using the procedure described below.
  • Carry out the functional test in the direction of escape.
  • You must carry out a functional test whenever the cylinder or the fastening screw is repositioned.
  • You will need an authorised identification medium to carry out the functional test.
  • Withdraw the dead bolt before the functional test.

U section:

No restore force on the cam

R section:

Restore force section towards U section

O section:

Top dead point in deadbolt throw - no restore force on the cam

OG:

Top threshold section

UG:

Lower threshold section

1:

Thumb-turn

2:

Cam position (concealed)

  1. With the cylinder engaged, first turn the thumb-turn in the direction of locking as far as the deadbolt throw in the 'R' section.
  2. You will feel the restore force. When you release the thumb-turn in this position, it must turn back to the 'U' section of its own accord.
  3. Lock the locking device and check the restore force. To do so, turn the engaged thumb-turn in the direction of locking through the 'R' section and into the 'O' section.
  4. The dead bolt extends. There is no restore force in the 'O' section.
  5. Move the thumb-turn slightly over the threshold between the 'O' and 'R' section in the same direction of rotation.
  6. The dead bolt will extend. The restore force must turn the thumb-turn automatically from this point as far as the 'U' section if it is released.
  7. If the thumb-turn does not automatically rotate as far as the 'U' section, either the fastening screw has been tightened too firmly or the locking device has been aligned incorrectly. The test is to be repeated after the fault has been eliminated. A fastening screw which has been tightened too firmly acts as a brake on the restoring force mechanism.
  8. Lock the door and check that the locking device functions correctly by pressing the door fitting or panic bar in the direction of escape.
  9. The dead bolt must spring back and it must be possible to open the door easily.
  10. If the dead bolt does not draw back when the handle is turned or the door fitting catches, either the locking cylinder or the locking device is incorrectly aligned or defective. The test is to be repeated after the fault has been eliminated as described above.

Please contact the lock manufacturer if you are unable to ensure that the locking device functions correctly after the functional test.
