The intelligent fire emergency lamp is a fire lamp that provides lighting for personnel evacuation and fire fighting operations. It usually uses an external power source and automatically switches to battery power when the power is turned off. Usually, high-rise buildings, shopping malls, entertainment places and other crowded places will be equipped with emergency lights. How much do you know about intelligent fire emergency lights?

2. Fire emergency lighting circuit. The lighting of this circuit is usually used as general public lighting and can be controlled by lighting switch. In case of fire, it can be switched to emergency state and directly connected to emergency evacuation lighting fixtures. At this time, the switch is out of control, and the intelligent fire emergency lamp is not controlled by the switch.
3. General public lighting circuit. This kind of lighting is an ordinary public lighting, not an emergency lighting, so it cannot be connected to the circuit with batteries, and it does not need to be connected immediately in case of fire. This kind of lighting is connected with the ordinary circuit of the emergency lighting distribution box, which can save the cost of establishing a separate distribution box, without increasing the battery capacity, and is easier to manage.
4. According to the actual project needs, the emergency distribution box can also provide DC power for fire protection.
