How Do I Choose the Best Rechargeable Emergency Light?
General name for lamps used in emergency lighting. The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicator lights, which are set up to guide trapped persons to evacuate or start fire fighting and rescue operations after the normal lighting power is cut off in the event of a fire. However, during the daily inspection, it was found that the unit has many problems in the selection, installation and use of fire emergency lighting. Therefore, the reasonable selection of the power supply control mode and wiring mode of the emergency lighting system and the daily maintenance work directly affect the role of the fire emergency lighting system. In daily life, check frequently to prevent problems before they occur!

- General name for lamps used in emergency lighting. The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs and indicators, which are used in the event of a fire.
- The emergency lighting system used in China is mainly based on the independent control of its own power supply. The normal power supply is connected to the ordinary lighting power supply circuit.
- It is found in daily supervision and inspection that it is very common that emergency lighting fixtures cannot be used normally due to incorrect wiring methods. Each emergency light should be provided with a dedicated line, and no switch should be set halfway. Two-wire and three-wire emergency lamps can be unified on a dedicated power supply. The setting of each special power supply should be combined with the corresponding fire protection code. If the emergency power source and the lamp rotate separately, the electrical connection should be made of high temperature resistant wires to meet the requirements of fire protection.
- Two-line system
- This connection is a common connection method for special emergency luminaires. It is suitable for emergency lights that are not used for normal lighting or continuous lighting for 24 hours (LED sign lamps belong to this category). After the power is cut off, the emergency lights will automatically light up.
- 1. It is necessary to accurately grasp the characteristics of various wiring methods, so as not to blindly connect, which will not be effective.
- 2. If emergency lighting is used as part of the usual lighting, a three-wire controllable connection method should be used.
- 3. For multi-story public buildings, if there is no consumer control center, the emergency lighting fixtures in various parts can be controlled by local switches (single lamp single control or multi-lamp control) or three-wire connection method centralized control in the distribution box. .
- 4. Projects with fire control center, in order to meet the requirements of fire control and related floor fire emergency lighting when the fire control center is opened.
- 1. In the engineering design, in order to facilitate the usual maintenance and management, it is best to provide special emergency lighting for each floor.
- Simple and practical production of emergency lights. It can automatically switch power supply in the event of a power failure. When the power is normally supplied, the backup battery is automatically charged and has a charging protection function. The working principle is described below. When the power supply is normal, J2 is energized and its movement
- the difference
