Electrical Maintenance – The Foundation of Safety and Reliability

To ensure that electrical systems remain safe and dependable, their condition must be under continuous supervision. Electrical maintenance (käit) is mandatory for all installations with a main fuse rating over 100 A.

The purpose of regular maintenance is to guarantee operational reliability and prevent electrical fires caused by worn-out or faulty connections. During maintenance, technicians inspect main and distribution panels, check circuit breakers and meters, tighten terminals, clean dust, and assess the general condition of equipment.

If necessary, a detailed report is prepared listing potential issues, based on which repairs or corrective actions can be scheduled.

Emergency Lighting System Maintenance – Visibility in Critical Moments

In addition to electrical maintenance, CitySecurity also performs emergency lighting system maintenance.

These systems ensure visibility and safe evacuation even when the main lighting fails. During service, all luminaires are tested, battery backup duration and capacity are verified, and additional measurements are carried out as needed. All maintenance work follows a scheduled service plan, ensuring the system’s constant readiness and reliable operation during emergencies.
