The emergency power supply can also have many other rich functions and become an emergency power supply in a broader sense For example, it can charge mobile phones and other electrical appliances, can be used as lighting, and can provide power to laptops; with an air pump, it can also pump tires; with an inverter, it can also output 220 volts to power other electrical appliances. In the process of emergency power supply application and development, fire power supply has special requirements because of its particularity. The EPS emergency power supply set according to specific needs is advanced and practical in the fire-fighting power supply industry. It can realize microcomputer monitoring and processing, and can realize fire-fighting facilities such as fire emergency lighting, emergency mercury lamps, fire elevators, water pumps, and smoke exhaust fans. Automatic control. UPS uninterruptible power supplies mostly provide emergency lighting and power supply for important places such as high-rise buildings, telecommunications network rooms, hospitals, financial centers, civil aviation airports, exhibition venues, theaters and cinemas, government offices, subway light rails, commercial real estate, petrochemicals, shopping malls and supermarkets.
　　 (1) Emergency lighting controller: The emergency lighting controller should be able to control and display the working status of all fire emergency lamps, emergency lighting centralized power supplies, emergency lighting distribution boxes and other accessories in the system.
(2) Emergency power supply: The emergency lighting conversion time of places with steps, ramps, escalators, etc., and places that may cause panic is not more than 0.25s, and the emergency conversion time of other places is not more than 5s, and it should be away from the heating. The heat source is above 1m.
　　 (3) Distribution box device: the distribution box or distribution box is set in the duty room, fire control room, power distribution room, and electrical distribution room;
When the distribution box or distribution box is installed on the wall, the height from the bottom edge to the ground is 1.3 m～1.5m, the side near the door shaft is not less than 0.5m from the wall, and the front operating distance is not less than 1.0m.
　　 (4) Emergency lighting: When a fire occurs in a building, the illuminance of the workplace still needs to be maintained at a normal illuminance value; it should be based on the ring
Reasonably select fire emergency lighting with protection categories and grades such as moisture-proof, waterproof, dust-proof, explosion-proof, shock-proof, corrosion-resistant and mechanical damage resistance.
