· Inspect and confirm all functions of the lock and the door fitting. Ensure that all
components of the lock (lock, door fitting and striking plate) work safely.
· All parts of the lock must be clean to prevent blockage.
· Check whether all components of the system still correspond to the list of ap-
proved components originally supplied with the system.
· Check that all operating elements are mounted safely.
· Measure the actuating forces for releasing the escape door lock with a dy-
namometer and log the results.
· Check whether the actuating forces for releasing the escape door lock have
changed significantly since the first installation.
