How much is the lump sum price per square meter for fire protection projects?

The cleaning price for commercial and other multi-story buildings is about 650-700 yuan/set. Generally, if auxiliary materials are included, it will increase by about 50-100 yuan per set; the price for automatic sprinklers without suspended ceilings is 65 -70 yuan/point, for suspended ceilings it is 75-80 yuan/point. If auxiliary materials are included, each point will increase by 5-10 yuan, and super height will increase by 5-10 yuan per meter.

The fire automatic alarm system is calculated according to potential at 65-70 yuan/point without suspended ceiling. Each point on the suspended ceiling increases by 5 yuan, and each point on the cladding auxiliary materials adds another 5 yuan. The extra height will be increased by 3-5 yuan/point for every one meter of super height.

Determination of the total number of detectors

First determine the number of detectors required for a detection area. The calculation formula is: N=S÷KA where: N—the number of detectors ( (only), take an integer; S—the area of ??the detection area (m2) A—the protection area of ??the detector (m2) K—the correction coefficient, which should be 0.7 to 0.8 for public places with more than 10,000 people. ;

Public places with a capacity of 2,000 to 10,000 people should take 0.8 to 0.9, public places with a capacity of 500 to 2,000 people should take 0.9 to 1.0, and other places Takes 1.0. Note: Both smoke and heat detectors are calculated using this formula.
