EMERGENCY SYSTEM BATTERY

Buildings with a higher level of power supply should be able to provide sufficient power under normal conditions, and should have sufficient backup power supply when the normally used power fails. When the building encounters an emergency (such as: fire, earthquake), there must also be an emergency system battery to ensure disaster relief and evacuation. Any building needs to consume a lot of electric energy so as to be used and operated normally. The main source of electric energy consumed by the building is the national or regional power grid. When the power grid cannot guarantee power supply or when in its own special conditions, small self-supply power plants will be used as the main power source or supplementary power supply; in many cases, diesel generator sets and battery energy storage equipment will be set up as an emergency system battery.

Although some loads have the same load level, they have different power supply considerations because of their different functions. Where need to install rechargeable emergency battery?

1) If the electricity for general work and life lighting in residential, office and commercial areas, life water pumps, and heating electricity in northern winter, as well as ordinary elevator electricity for non-fire use are not available, the lives of residents, business of mall,normal work of office would be affected,which is truly unconvenient.

2) As for electricity for air-conditioning, entertainment activities in residences and offices, and electricity for ventilation in ordinary places, if they cannot be powered, it will make people feel uncomfortable to a certain extent.

3) If the power supply of smoke exhaust fans, stair pressurized fans, fire elevators, fire pumps, and personnel evacuation lighting used in various places during fires cannot be guaranteed, it will pose a great safety hazard and even directly cause accidents, threatening the safety of buildings and personnel.

In the above places, the third is related to the safety of buildings and personnel, and electricity must be guaranteed; when the grid power supply cannot meet the needs, an emergency power supply must be installed.

Different rechargeable emergency battery voltages

With the emergence of more and more wireless devices, people's demand for emergency system battery continues to increase. Rechargeable emergency battery refers to a kind of battery with a limited charging times, which is rechargeable, used with a charger. The market generally sells Size AA and AAA battery, but there is also D size battery. The advantages of rechargeable batteries are economy, environmental protection, sufficient power, suitable for high-power, long-term electrical appliances (such as walkmans, electric toys). The voltage of the rechargeable emergency battery is lower than that of the disposable battery of the same model. The AA battery is 1.2 volts, and the 9V rechargeable battery is actually 8.4 volts. Now the general charging times can be about 1000. This rechargeable emergency battery is very suitable as an emergency battery for some important equipments, such as our common emergency lights:

Emergency light is the general term for lamps used for emergency lighting. The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicator lights. It is set up to guide the trapped people to evacuate or launch fire rescue after the normal lighting power supply is cut off in the event of a fire. Therefore, emergency lights also need rechargeable emergency light battery. The 6 volt rechargeable battery for emergency light is used as emergency battery for emergency lights in daily life. Of course, there are also emergency light 12v battery. They can all guarantee the lighting of emergency lights and reduce the safety problems caused by the emergency light that doesn't work.
