What are the requirements for fire protection construction in shielded rooms?

Author:admin   AddTime:2021-04-12

The fire protection system of the shielded room is constructed based on the following principles:

Adopt high-sensitivity automatic fire alarm system;

Use environmentally friendly FM200 gas fire extinguishing system; FM-200 gas fire extinguishing system protection area and storage environment temperature is 0-54 ℃, storage pressure 25kg/cm2;

The gas fire extinguishing system can be started in three ways: automatic, mechanical manual and remote start; it is equipped with a backup power supply and the operation time is 24 hours;

All the maintenance components of the gas fire protection zone meet certain pressure resistance requirements, and the allowable pressure difference is not less than 1.2kPa. The fire resistance rating of the partition wall and door of the protection area is not less than 0.6h; the fire resistance rating of the suspended ceiling is not less than 0.25h;

The fire extinguishing system can automatically detect whether there are people in the protected area before starting;

When a fire occurs, an automatic sound and light alarm will warn people in the corresponding area to evacuate.

Principle of fire prevention:

When a fire occurs in the protection area and the smoke detector alarms, the automatic fire alarm system will alarm, flashing lights, and alarm bells to prompt the staff to evacuate the fire area; when the smoke detector alarms and the temperature detector alarms at the same time, the fire Automatic alarm system alarms, flashing lights and buzzers outside the protection area, control the linkage system to cut off the non-fire power supply, turn off the corresponding area fire dampers and other linkage equipment, and start the infrared detection system; when the infrared detection system confirms that there is no person in the corresponding protection area When the time, start the gas fire extinguishing system to extinguish the fire



Standards and specifications for the construction of fire protection systems in shielded rooms:

Code for fire protection of building design GBJ16-87

Code for design of automatic fire alarm system GB50116-98

Code for design of electronic computer room GB50174-93
