Emergency light installation specifications
Everyone knows the importance of emergency lights. Emergency lights are required to be installed in many places. The more common places are schools, office buildings, shopping malls and other overall buildings. It is conceivable that the function of emergency lights should not be underestimated. So what are the emergency light installation specifications and precautions for the use of emergency lights? Don't worry, BENWEI will explain it to you, let's take a look.
Emergency light installation specification
1. Generally speaking, this kind of lights will be placed on the door frame of the safety exit, about 2m above the ground. Of course, for some large electronic markets, shopping centers and other places, the double-head emergency lights will be directly wall-mounted on the pillars.
2. In daily life, it is very common that the lamps cannot be used normally due to the wrong connection method. Therefore, it is recommended that each emergency light be equipped with a dedicated circuit and no switch is set in the middle. The two-wire and three-wire emergency lights can be unified on the dedicated power supply. , At the same time, the settings of each dedicated power supply should be combined with the corresponding fire protection regulations.
3. In the event of a fire, since there is less smoke close to the floor, people's instinct is to bend over or crawl forward during evacuation. Therefore, local high-illuminance lighting is more effective than the uniform illuminance brought by high-level installation, so it is recommended Low-level installation, that is, provide emergency lighting for evacuation close to the ground or at ground level.
Precautions for the use of emergency lights
1. First, determine the location of the power box and lamps, and then install them in the correct way, and prepare the three-core and five-core cables of the corresponding length.
2. Use a hexagonal wrench to open the power box cover of the cable inlet and remove the ballast. Connect one end of the pre-prepared three-core cable from the output of the power box to the ballast in accordance with the requirements of explosion-proof, then connect one end of the five-core cable from the input of the power box to the ballast, and then connect the battery Insert the corresponding battery positive and negative wiring positions on the circuit board, and finally close the power box cover to fix it.
3. After installing and fixing the lamp and the power box according to the predetermined position, use a hexagonal wrench to open the screw on the front cover of the lamp. After opening the front cover, connect the other end of the three-core cable to the lamp in accordance with the explosion-proof standard. After the connection is completed, fix the front cover, and then connect the other end of the five-core cable to the city power according to the explosion-proof standard. Then lighting can be achieved.
4. Turn the emergency function switch key on the ballast to the OFF position, and the external wiring control emergency function of the lamp will be activated. If you don’t want to use a wire to control the emergency, then pull the switch to the ON position, and it will be automatic when the power is cut off. Turn on the emergency function.

The charging time is about 14 hours. If it is not used for a long time, it needs to be charged once every 3 months, and the charging time is about 8 hours.
The above is the explanation of the knowledge of emergency light installation specifications and emergency light use precautions, so I will stop here. The content is for your reference only, and I hope it can be helpful to everyone.
