Shenyang emergency fire lighting It plays a very important role in our daily life. In the case of power failure, the emergency light can stay on for about 90 minutes, which is a low standard. If any emergency supply , at least 20 minutes longer. The fire emergency lights are usually connected to the mains or generate electricity. The AC power is used to charge the emergency lights' standby power supply (rechargeable battery), and the main power indicator on the emergency light cover is on.
1. When charging, the charging indicator light will be on, and the battery will be fully charged quickly and correctly within 24 hours. Then it will turn to trickle charging and wait, and the charging indicator light will be off.
2. When the fault light is on, it indicates that the emergency light is faulty and needs to be repaired. When there is a sudden power failure, the emergency light will be on because of the power supply of the back, so as to achieve the function of emergency lighting.
Next, we want to explain to you why the emergency light always alarms and sounds, and what causes this?
1. Sometimes it is found that the emergency light also has an intelligent fault voice alarm function, but sometimes it will always ring. It may be that the emergency light has no power supply, so it will send out an emergency alarm sound, which can give a prompt.
2. But in this case, when the emergency light is in the main power state, it will not emit such a problem. If it keeps ringing, you can manually unplug the power supply to eliminate the alarm phenomenon.
3. Or we can adjust the duration of the button, adjust its mode, and effectively avoid the problem that the emergency light will always sound.
4. If the above methods still fail, it may be that the battery has a fault or the circuit board has a problem, and the circuit board is prone to short circuit, which will lead to the problem of its alarm horn. It is necessary to disassemble the shell and destroy the alarm horn inside.
