1,、選購消防應(yīng)急燈要注意買正規(guī)生產(chǎn)廠家的產(chǎn)品，有些冒牌產(chǎn)品為了降低成本,，采用的元件多是劣質(zhì)產(chǎn)品,，用不長時間就會故障頻出，給消費者造成不應(yīng)有的損失,。挑選時拿起來搖晃幾下,，檢查內(nèi)部蓄電瓶和電源變壓器固定部件是否牢固，如果內(nèi)部有響聲,，則說明內(nèi)部元件松動,，反之則說明固定良好。
1. When purchasing fire emergency lights, we should pay attention to the products of regular manufacturers. In order to reduce the cost, some counterfeit products mostly use inferior components, which will break down frequently in a short time, causing undue losses to consumers. Pick it up and shake it a few times during selection, and check whether the fixed parts of the internal storage bottle and power transformer are firm. If there is a sound inside, it indicates that the internal components are loose, otherwise, it indicates that they are well fixed.
2,、檢查功能開關(guān)是否正常,。將開關(guān)置于雙熒光燈檔位.這時兩支燈管應(yīng)立即同時點亮，且亮度一致而無閃爍現(xiàn)象,。把耳朵貼在燈殼上,，仔細聽一下內(nèi)部的升壓變壓器是否有漏電現(xiàn)象，如果有漏電現(xiàn)象,，升壓變壓器會產(chǎn)生“滋滋”的響聲,。
2. Check whether the function switch is normal. Place the switch in the dual fluorescent position At this time, the two lamps shall be lit at the same time immediately, and the brightness shall be consistent without flickering. Stick your ear to the lamp shell and listen carefully to whether the internal step-up transformer has leakage. If there is leakage, the step-up transformer will make a "Zizi" sound.
3、接通電源,，充電指示燈應(yīng)點亮,，聽聽內(nèi)部電源變壓器是否有因鐵芯松動而產(chǎn)生的“嗡嗡”聲。
3. When the power is turned on, the charging indicator light should be on to listen to whether the internal power transformer has a "buzzing" sound caused by loose iron core.
4,、使用應(yīng)急燈要注意,，燈光發(fā)暗、熒光燈啟動困難時應(yīng)立即進行充電,，一次充電約需14個小時,。長期不用時，應(yīng)3個月充一次電,，時間約為8小時,。
4. Pay attention to the use of emergency lights. When the lights are dim and the fluorescent lights are difficult to start, they should be charged immediately. One charge takes about 14 hours. When it is not used for a long time, it should be charged once every 3 months for about 8 hours.
