Currently, high-rise buildings, shopping malls, entertainment venues, etc. must have fire emergency lighting. So, should fire emergency lighting lamps or EPS fire emergency power supplies be used for emergency lighting? Let's compare them together.
Fire emergency lighting refers to electrical appliances designed to provide illumination and assist in escape when no external power source is available during a fire. It normally operates on an external power supply and automatically switches to emergency mode when the power is lost. Currently, it is widely used in high-rise buildings, shopping malls, entertainment venues, and other densely populated areas.
EPS power supplies, also known as EPS emergency power supplies or fire emergency power supplies, are emergency power supplies used in important buildings today for power supply assurance and fire safety. They mainly consist of input/output units, charging modules, battery packs, inverters, monitors, and output switching devices. They are widely used in building lighting, road and traffic lighting, power systems, industrial and mining enterprises, fire elevators (fire pumps), and other fire-fighting equipment.
1. Emergency lighting switches on in about 2 seconds after a power outage, which may cause a brief interruption. In contrast, EPS emergency power supplies can switch on in as little as 0.18 milliseconds without any power outage.
2. Fire emergency lighting fixtures are scattered and numerous, lacking centralized management capabilities, making management inconvenient. The condition of the fixtures can only be determined when they are lit. In contrast, EPS centralized intelligent management allows for remote monitoring and management of power, and can monitor battery internal resistance, achieving preventable and controllable operation, low failure rate, and convenient management.
3. Emergency lighting fixtures typically use small-capacity batteries, usually 4AH, which have a lifespan of about 1 year and high maintenance costs. EPS fire emergency power supplies, on the other hand, are generally designed with a battery life of 5 to 8 years and a main unit lifespan of 25 years, resulting in low maintenance costs.
4. There are strict requirements for the types of emergency lighting fixtures, but EPS power supplies have no requirements for lighting fixtures.
Meanwhile, EPS power supplies can power fire pumps and other fire-fighting loads other than emergency lighting.
Of course, the advantages of EPS power supplies are unmatched by emergency lighting fixtures, but the initial investment in EPS power supplies is relatively high.
