Gas fire extinguishing system simulation start-up test scheme

Unread post by vedard »

The gas fire extinguishing system project needs to carry out simulated start-up test to verify the reliable performance of the gas fire extinguishing system.The simulation start-up test should be carried out after the installation and debugging of gas equipment, alarm equipment and gas fire extinguishing equipment.
I. Test basis:
Code for Construction and Acceptance of Gas fire Extinguishing System GB50263-2007
Two, test content
1. Manually start the experiment
2, automatic start test
Iii. Preparation before the test
Gas alarm system and gas fire extinguishing system have been installed and debugged, and test tools (stopwatch, sound level meter, multi-meter, point-type smoke detector tester, point-type temperature detector tester, etc.) have been available.
Professional personnel should check whether all lines are properly connected.
Under the guidance of professionals, the starting solenoid valve of gas fire extinguishing system should be removed for simulation test.
4. Test method
3.1 Manual simulated startup test can be carried out according to the following methods:
Press the manual start button to observe whether the relevant action signal and linkage device action is normal (such as sound and light alarm, start the load response at the output end, close the ventilation and air conditioning, fire valve, etc.).
Manually activate the pressure signal feedback device and observe whether the gas jet indicator light outside the relevant protection area is normal.
3.2 Automatic simulated startup test can be carried out in the following way:
1 Connect the starting output end of the fire control unit with the driving device in the corresponding protection area of the fire extinguishing system.Drive device should be separated from valve action mechanism.It can also be replaced by a load whose starting voltage and current are the same as those of the driving device.
2. Make any fire detector in the protected area operate manually, and observe whether the related alarm devices operate normally after the output of a single fire alarm signal (e.g. alarm bell, buzzer, etc.).
3 Manually simulate fire alarm to make another fire detector in the protected area operate, and observe whether the relevant action signals and linkage devices operate normally after the output of compound fire alarm signal (such as sound and light alarm, start the load on the output end, close the ventilation and air conditioning, fire valve, etc.).
V. Judgment of test results
The results of simulated start-up test shall meet the following requirements:
1 the delay time is consistent with the set time, and the response time meets the requirements;
2. Sound and light alarm signals are correct;
3. The linkage device acts correctly;
4 The driving device is reliable.
Six, test matters needing attention
1. The test should be carried out in strict accordance with the guidance of professional personnel to avoid damage to equipment or injury.
2, the solenoid valve should be removed from the bottle group before the test, so as not to start the gas extinguishing system by mistake.
3, after the test should be restored and check the systemg
