What deviations are visible during maintenance? · Villa
Periodic maintenance focuses on visitor image, interior monitors, voice connection and door control. Compare the current operation with the agreed configuration. Document deviations before settings change. Distinguish between control, cleaning, adjustment, and repair. Discuss defects that fall outside the maintenance task and check after work whether normal operation still works. We complete the check against visible visitor image, understandable conversation and the correct door opener per monitor.
