Why is regular maintenance important?
Ensure safety:
Wear and tear on locks and door closers often goes unnoticed. Regular maintenance helps to identify and prevent security gaps at an early stage.
Save costs:
Preventive maintenance prevents expensive emergency repairs and extends the service life of your systems.
Minimize liability:
For property management companies, schools, and public buildings, the functionality of fire doors and escape routes is required by law.
