Responsible personnel
The building owner or operator must establish who is responsible for keeping the emergency lighting system in proper operating condition. Maintenance activities should follow the system documentation, the applicable edition of HRN EN 50172 and the instructions of the equipment manufacturer.
Functional and duration testing
Routine inspections and functional tests help identify failed luminaires, charging faults and problems with switching to the emergency supply. Duration tests verify whether the power source can maintain operation for the specified period. The schedule and method must be based on the applicable requirements and the installed system.
Documentation
Record inspection dates, faults, remedial work, battery replacements and the results of functional and duration tests. A complete log enables trends to be identified and supports a reliable handover between the building operator and the service provider.
Further checks
Inspect the visibility and legibility of evacuation signs, changes to escape routes and any building alterations that affect lighting coverage. The original Croatian handbook includes a short chapter on these obligations; its source pages can be opened below.
MAINTENANCE AND TESTING OF EMERGENCY LIGHTING
Under the Fire Protection Act and the Occupational Safety Act, employers must maintain buildings used for work in a condition that does not endanger workers' health and safety and must inspect certain installations at intervals prescribed by technical regulations. Under the conditions specified, the emergency lighting system must be inspected once a year.
The inspection establishes whether the system meets the provisions of the following laws, technical regulations and standards:
HRN EN 50172 – Emergency escape lighting systems (Chapter 7, clauses 7.1, 7.2 and 7.4).
HRN EN 62034 – Automatic test systems for battery-powered emergency escape lighting (Chapter 5, clauses 5.1 and 5.2).
MAINTENANCE AND TESTING OF EMERGENCY LIGHTING
Chapter 7 of HRN EN 50172 explicitly specifies mandatory maintenance and servicing of emergency lighting. The owner or occupier of the premises must appoint a responsible person who will ensure regular maintenance and facilitate any work necessary to keep the system in good working order.
Tests should be performed at the following intervals:
Daily – visual check of system condition (performed by the central unit automatically).
Monthly – functional test (performed by the central unit automatically).
Annually – battery test (performed by an authorised service technician).
HRN EN 62034 specifies testing requirements for emergency lighting systems supplied at up to 1,000 V. The document applies both to self-contained luminaires and luminaires powered from a central battery.
The functional test (checking the proper operation of emergency luminaires) must be performed monthly, and the battery test (checking battery condition/capacity) annually.
