Case (5)

A high-rise commercial complex has two floors underground, 30 floors above ground and one to five floors above ground for shopping malls. According to the requirements of the code, automatic fire alarm system, emergency lighting and evacuation indication system, smoke control system and other building fire protection facilities are set up. The owner entrusts the fire control technical service institution to test the fire control facilities. The test process and results are as follows:

1, function detection of automatic fire alarm facilities

Twenty smoke detectors were randomly selected at the scene, and the alarm function was tested by adding smoke. Only 1 did not give an alarm, only 1 did not display the alarm position information correctly, and the rest 18 had normal alarm function.

2. Detection of linkage control function of fire alarm and fire emergency broadcast.

The linkage controller is set to automatic working mode. Smoke on the eighth floor triggers 1 smoke detector alarm, and the acousto-optic alarm on the eighth floor starts, and smoke on the eighth floor triggers another 1 smoke detector alarm.

3. According to the current national standard Code for Design of Automatic Fire Alarm System (GB50 1 16), is the linkage control function of smoke exhaust system in commercial complex normal? Why? What is the main reason why the linkage control smoke exhaust fan does not start?

4. Which type of sparse indicator light should be selected for the commercial complex? Is the function of fire emergency lighting and evacuation indication system normal? Why?

5. What is the reason why the ground evacuation indicator light of the commercial complex building did not light up during the functional test of the fire emergency lighting and evacuation indication system?

Case (6)

A financial data center building in Northeast China has four floors with a total construction area of 1 1200m2. The first floor is high and low voltage distribution room, fire pump room, fire control room, office, etc. The second floor is the recording (paper) media library, the third floor is the recording (paper) media library (backup) and the important customer file room, and the fourth floor is the data processing room. The second and third floors are equipped with pre-action automatic sprinkler systems, using 896 sprinklers (including 365,438 ceilings, 3 16 ceilings and 264 others). The high and low voltage power distribution room, data processing room and communication room are protected by combined distribution IG54 1 mixed gas fire extinguishing system. IG54 1 96 fire extinguishing agent storage bottles with specifications of 90L in the mixed gas fire extinguishing system, with indoor temperature of about 5℃.

Fire technical service agencies found that:

1. The pre-action automatic sprinkler system is equipped with two pre-action alarm valve groups, which are considered to be in line with the relevant provisions of the current national standard Code for Design of Automatic Sprinkler Fire Extinguishing Systems (GB50084) by the personnel of fire technical service institutions.

2. The pre-action automatic sprinkler system is in paralysis. According to the owner's report, the air pump control box of the system displays low-pressure alarm for a long time, resulting in the air pump running all the time. All water supply and gas supply pipelines, components and interfaces have been subjected to water pressure test and air tightness inspection for many times, and the air tightness of the air pump has been checked for many times, and no problems have been found, so the system has to be shut down.

3. The lower part of the doors and windows of the high and low voltage distribution room is a louver as a pressure relief port.

4.IG54 1 The pressure gauge for fire extinguishing agent storage in gas fire extinguishing system is 13.96MPa. The personnel of fire technical service institutions think that the pressure is low, and there may be a slow leakage of fire extinguishing agent.

According to the above materials, answer the following questions (***20 points).

1. How many pre-action alarm valve groups should the pre-action automatic sprinkler system be equipped with? Why?

2. When testing the pre-action automatic sprinkler system, which equipment or components should be tested at least besides the air pump?

3. List the reasons that may cause the pump control box of pre-acting automatic sprinkler system to display low-pressure alarm for a long time and the air pump keeps running.

4. Question: Does the pressure relief port of high and low voltage power distribution room meet the requirements of standards and specifications? Briefly explain why.

5. Is it correct for the personnel of fire technical service organization to think that the storage pressure of fire extinguishing agent in IG54 1 gas fire extinguishing system is low and there may be slow leakage of fire extinguishing agent? Briefly explain why.
