Modernization of emergency lighting in industrial environments: case study of technical and economic evaluation of systems with automatic testing

Abstract

 The present article analyzes the modernization of emergency lighting systems in industrial environments through the adoption of the IEC 62034 standard, which regulates automatic test systems (ATS). The study compares two technological approaches: systems with individual batteries and systems with centralized batteries, both evaluated with and without automated testing. Key aspects such as operational efficiency, safety, regulatory compliance, and maintenance cost reduction are examined. The analysis is framed within the common challenges faced by industries, such as the need to upgrade infrastructure, improve sustainability, and ensure the reliability of evacuation systems. Through a real-world case study, the limitations of traditional systems—such as low reliability and high operational costs—are identified, and key performance indicators are compared before and after the implementation of automated solutions, including preventive maintenance, energy efficiency, and overall system reliability. The results show that systems with automatic testing offer greater economic profitability and faster return on investment. In the analyzed case, luminaires with individual batteries and automatic testing proved to be the most cost-effective option. However, centralized battery solutions stand out for their lower environmental impact and their suitability in facilities with high-mounted luminaires, where maintenance is more complex. This study provides a practical guide for companies seeking to optimize their emergency lighting systems in response to the demands of an increasingly competitive and regulated industrial environment.
