Emergency lighting system is divided into centralized controlling type and non-centralized controlling type according to the control form, and centralized power supply type and non-centralized power supply type according to power supply type. At present, emergency lighting system with centralized power supply and centralized control are widely used in the market.Emergency lighting system is divided into centralized controlling type and non-centralized controlling type according to the control form, and centralized power supply type and non-centralized power supply type according to power supply type.

Emergency lighting system installation
(1) The emergency lights should be evenly installed, and must be installed on the roof or the side wall more than 2m away from the floor of the building.
(2) When installing on the top of the side wall, the distance from the bottom to the ground should not be less than 2m. When installing on the side wall below 1m from the ground, it should be embedded installation. Make sure that the light is below the horizontal line where the emergency light is installed. It must not be installed on the ground or on the side wall between 1 and 2m.
(3) When hanging installed, you need to use metal suspenders or suspension chains, and the upper end of the suspenders or suspension chains should be fixed on the building structure.
 
Emergency lighting system power distribution box and device installation
(1) Emergency lighting power distribution boxes and devices should be installed more than 50mm above the ground, and the minimum width of the channels in front of and behind the screen should comply with the regulations in “Low-Voltage Power Distribution Design Code”.
(2) When the emergency lighting power distribution box and device are installed on the wall, the height from the bottom to the ground should be 1.3-1.5m, the side near the door shaft should not be less than 0.5m from the wall, and the front operating distance should not be less than 1.0m.
 
Emergency lighting system centralized power supply installation
(1) The emergency light should be installed in places that are free of corrosive gases, steam, flammables and soil. The battery should be installed in a well-ventilated place, and it is strictly forbidden to be placed in a sealed environment, with flammable gas pipelines, warehouses and other places.
(2) When installed on the floor, it should be more than 150mm above the ground, and the channels in front of and behind the screen should be able to meet the needs of battery replacement.
 
Emergency lighting system controller installation
(1) When installing on the ground, the bottom edge should be 0.1-0.2m higher than the floor.
(2) The emergency lighting controller should be installed firmly without tilting, and when it is installed on a light wall, reinforcement measures should be taken.
(3) The main power supply of the emergency lighting controller shall be clearly marked, and shall be directly connected to the fire-fighting power supply, and the use of power plugs is strictly prohibited. There should be a direct connection between the emergency lighting controller and its external backup power supply. The grounding should be firm and there should be obvious signs.
(4) The control circuit of the emergency lighting controller should be piped separately. The cables or wires introduced into the emergency lighting controller should be neatly arranged to avoid crossing, and should be fixed firmly. The cable core wires and the ends of the equipped wires should be marked with numbers, consistent with the drawings, and the handwriting should be clear and not easy to fade. Each terminal of the terminal board should not have more than 2 wires, the cable core and wires should have a margin of not less than 200mm, and the wires should be bundled.
Function debugging
A. Simulate the fire linkage control signal, the emergency lighting controller should control the relevant fire emergency lamps to enter the emergency working state.
B. The emergency lighting controller should be able to control and display the working status of all emergency lights, fire emergency power supplies, emergency lighting distribution devices and other accessories in the system.
C. Control the fire emergency lighting controller manually, so that the emergency lights can switch to the emergency working state.
