Location of installation of fire emergency lights
In accordance with the building design fire code and the high-level civil design fire code, fire emergency lighting lamps should be installed at the following parts of the building
1. Closed stairwells, smoke-resistant stairwells and their front rooms, fire elevators and their front rooms
2. The electrical distribution room, fire control room, automatic generator room, fire pump room, smoke-smoke control room, battery holding room for fire-fighting power, telephone main room and other rooms that need to remain in fire-fighting environments for fire-fighting purposes at all times
3. Exhibition halls, operating halls, studios with more than 1,500 m2 floors, studios with more than 2000 m2 floor space, densely populated basements with more than 300 m2 floor area, etc.
4. Evacuate passageways (safe exit passages) in public buildings and inner passageways of more than 20 metres in length
Reference to the location of fire emergency lamps installation:
I. Guidelines for the installation of fire emergency lighting
Common dual-head fire emergency lights are installed at the door frame of the exit gate of the evacuation corridor, on the corridor, on the wall of the safe exit passage, at a distance of approximately 2 metres above the ground; at large electronic markets, shopping malls, etc., the two-head emergency lights are mounted directly on the pillars。
The installation of fire-fighting emergency lamps is better protected from physical impact; they are too high to affect the light effect of power outages and timelighting, and the difficulty of repairing and debugging emergency lamps
Two-headed fire emergency lighting lamps are sufficient at an altitude of approximately 2. 2 metres; depending on the actual conditions of the use site, the installation may be adjusted appropriately when the space used is large and the intensity of use of emergency lamps increases; provided that the requirements of the fire inspection receiving and inspection department are met
Ii. Installation guidelines for emergency safety exit lights
Fire emergency exit lamps can be divided into security exit lights and evacuation route signposts, which are usually installed inside buildings at the point of exit to the normal outdoor exit and emergency route. (a) the entrance to the stairwell and the front room of the fire elevator on the various floors of the multi-storey and high-rise buildings; and the entrance to the evacuation passage and exits to the front, side and stairs
Fire safety exit lamps are generally installed above the exit door frame and, if the door frame is too high, can be installed at the side of the door frame; they are installed at an altitude of 2. 2-2. 5 metres in order to prevent the visual impact of the smoke generated by the fire
When fire response lights are evacuated, the correct emergency escape exit can be found from any location, and the distance between emergency evacuation instruction lights installed on fire response evacuation routes or safe emergency exit routes should not be greater than 20 metres。
