Fire emergency lighting power supply: The "last light" safeguarding life evacuation routes
 
In critical moments when main power supply is interrupted due to fires or other emergencies events, the fire emergency power supply on lighting is an independent power system that automatically starts up to provide essential lighting for the safe evacuation of people and fire rescue operations. It is an indispensable life safety guarantee device in modern buildings, especially in densely populated public places. With the increasing global emphasis on building safety regulations, understanding its international access standards, technical key points, and maintenance requirements is of vital importance for product manufacturers, exporters, and engineering parties. 
 
What is a emergency power supply?
 
A fire emergency lighting power supply is a backup power device independent of the normal power supply system. When a fire breaks out in a building or there is a power failure in the city, it can automatically provide power to the evacuation indicator lights and emergency lighting fixtures, ensuring the visibility of the escape routes. 
 
II. Exporting Overseas: Key Market Access Characteristics and Standards
Different countries and regions have established corresponding access thresholds for fire emergency lighting products based on their safety regulations and engineering practices. The following is an overview of the characteristics of some markets in Europe, the Middle East, and South America and North America.
 
1. Stringent Certification: European Market
Products must strictly comply with EN IEC 60598-2-22 (Special Requirements for Emergency Luminaires) and EN 50171 (Central Safety Power Supply Systems) standards. Entering the EU market, mandatory CE certification is a prerequisite, indicating that the product meets safety regulations such as the Low Voltage Directive. Centralized power supply split emergency lighting power systems are widely used in such high-standard projects, and their continuous power supply time is usually required to reach over 90 minutes.
 
2. Converging Standards: Middle East Market
Taking the Gulf countries as an example, market access follows technical regulations such as GSO IEC 60598-2-22:2024 issued by the Gulf Standardization Organization (GSO). This standard directly adopts the framework of the International Electrotechnical Commission (IEC) and clearly stipulates requirements for emergency time and battery performance. To cope with the local high-temperature climate, emergency lighting power systems with aluminum alloy shells are a good choice, as their excellent heat dissipation and anti-corrosion properties help meet protection levels (such as IP54) and long-term reliability requirements.
 
3. Regulatory Updates: South American Market
Take Argentina as an example. According to its Resolution No. 16/2025, electrical equipment must meet basic safety and quality requirements and recognize IEC international standards. Test certificates issued through the CB system are valid in this country, providing convenience for manufacturers. To meet the diverse building needs in the local area, product solutions can be flexibly configured. For instance, full-power emergency lighting power supplies are provided for large venues, while reduced-power emergency lighting power supply modes are adopted for medium and small-sized venues to extend the power supply time.
 
4. Strict System: US Market
The US market has a strict access system, with the core being obtaining UL 924 standard certification. This standard is the cornerstone for products to meet key regulations such as the National Electrical Code (NFPA 70), Life Safety Code (NFPA 101), and International Building Code (IBC). Products must automatically start emergency lighting within 10 seconds after a normal power failure - and the continuous power supply time is usually required to be no less than 90 minutes. Whether it is an integrated emergency lighting power supply or a centralized split emergency lighting power supply, both must pass this certification and strictly follow relevant standards such as NFPA 110 (Generator Systems) or NFPA 111 (Energy Storage Systems).
 
5. Flexible Solutions: Meeting Diverse Demands
Facing the complex requirements of different global markets, manufacturers need to provide flexible product solutions. For example, integrated emergency power supply are popular in small or standardized projects due to their easy installation; while Split-Type emergency power supply, with their centralized power supply and easy management advantages, are more suitable for large commercial complexes or industrial plants to meet specific regulations on system capacity and control in different regions.
 
III. Core Installation Technical Requirements: Deployment Based on Local Conditions
Correct installation is the foundation for ensuring the reliability of the system, and it must strictly follow the technical specifications based on the application scenario.
 
1. Ground of evacuation corridors and passages
The directional indicator lights installed on the ground should be parallel to the ground surface, and the edge should be no more than 3 millimeters higher than the ground level to ensure that they are not tripped over and can withstand foot traffic. The power supply circuit for this area usually requires a high protection level and stable output of a full-power emergency lighting power supply.
 
2. High-rise Buildings and Large Spaces
In civil buildings or large public buildings with a height exceeding 100 meters, after the system emergency is activated, the continuous power supply time of the battery should not be less than 1.5 hours. This requires the configuration of a large-capacity centralized power supply or batteries built into the lamps, and reasonable planning of the switching logic for the reduced-power emergency lighting power supply to extend the lighting time in critical areas.
 
3. Emergency Lighting Distribution Box
In the output circuits of emergency lighting distribution boxes or centralized power supplies, it is strictly prohibited to connect ordinary sockets or other loads outside the system. They must be dedicated circuits. During installation, ensure that the box is clearly marked to facilitate quick identification and operation in emergency situations.
 
IV. System Maintenance Procedures: Ensure constant availability 
Regular professional maintenance is the lifeline that ensures the emergency lighting system functions 100% at critical moments.
 
1. Monthly visual and functional inspection
Check whether all Led emergency lighting fixtures and indicator lights are in good condition without any obstructions. Manually test the emergency startup function and observe whether the lamps can light up quickly.
 
2. Quarterly comprehensive discharge test
Simulate a main power failure and trigger the system to enter emergency mode. Record the power conversion time and the actual duration of the full power output emergency power supply, and compare it with the standard requirements.
 
3. Annual battery performance test
Perform deep discharge and capacity tests on the batteries. Measure and record the floating charging voltage and current of the battery group, assess the battery health, and replace those with excessive performance degradation.
 
4. Cleaning and environmental management
Clean the lamp housing and light-transmitting surface to ensure the best light efficiency. Check the installation environment to ensure good ventilation and heat dissipation around the power equipment, and no corrosive gases or debris accumulation.
 
5. Professional maintenance and record-keeping
The maintenance work should be carried out by professionals. After each maintenance, update the system records, including the test date, results, identified problems, and corrective measures, to form a traceable complete file.
