What area of fire sprinklers does the hotel need?

Don't install spray if the hotel fire protection is less than 300 square meters. According to the national standard "Code for Fire Protection Design of High-rise Civil Buildings" GB50045-95, automatic sprinkler systems are required to be installed in high-rise buildings, such as song and dance halls, karaoke halls (including restaurants with karaoke function), nightclubs, video halls, projection halls, saunas (excluding bathing parts), amusement halls (including electronic amusement halls), internet cafes and other entertainment places. And the above places should be close to the outer wall.

Should not be arranged on both sides and ends of the bag-like walkway. The maximum capacity is calculated by one person per square meter in the video hall, and one person per square meter in other places, and the area is calculated by the building area of the hall.

In the places listed in the first point, you can freely choose whether to install an automatic sprinkler system below 300 square meters, and only a simple automatic sprinkler system can be installed between 300 square meters and 1000 square meters, that is, municipal water can be directly connected without a pump. To sum up, as an Internet cafe with a single building area of less than 300 square meters, you only need to install simple fire safety facilities, such as fire extinguishers, automatic sprinkler systems, evacuation passage signs, emergency lighting and so on.
