There are a total of 10 random test questions about the operation of fire protection facilities in the random test of the intermediate consumer examinationThe examiner will randomly select about 3 questions during the intermediate monitoring offline exam, and the examiner will randomly select about 2 questions during the intermediate maintenance offline exam.
The operation of some of the more important fire-fighting facilities will be extracted frequently, such as the operation of automatic fire alarm controller, automatic sprinkler system, etc. Students should pay attention to the oral answers in the on-site test, listen to the examiner's questions clearly, and if it is a different part of the operation, it needs to be divided into several steps to answer separately, and the answers should be complete and accurate.
10 random exam questions for fire facility operation:
Identification point 13: historical information inquiry
Identification point 16: linear fire detector fire alarm and fault alarm function test
Identification point 17: fire display disc function test
Identification point 18: Classification of types of sprinkler systems
Identification point 20: operation of the electrical control cabinet of the pressure increase (stabilizing) pump unit
Identification point 21: firefighting ** operation
Identification point 24: fire shutter operation
Identification point 25: fire door operation
Identification point 26: emergency lighting controller operation
Identification point 27: elevator emergency landing operation
Six of them are often extracted from the actual offline exams, and the oral answers to the historical information query, detector function test, and fire display panel are shared in the previous article
Next, let's look at the other three: the electrical control cabinet of the pressure increase (stabilizer) pump, the fire shutter and the operation of the elevator.
Identification point 20: operation of the electrical control cabinet of the pressure increase (stabilizing) pump unit
The specific oral answer is as follows:
1. Judge the working state of the control cabinet: first find the manual automatic conversion button, and now the position pointing is xx state, (there is an indicator light to see the indicator light), so judge the current xx state.
2. Switch hand automatic state: through the hand automatic transfer switch, turn the knob to the automatic position (click the button automatically), and the switch is completed.
3. Switch the main and standby pump conversion: after manually moving, check the current X pump position of the indicator light, turn the button (click the X pump button), and switch the X pump to the position of the main pump.
4. Switch the dual power supply to the automatic state: open the dual power supply control cabinet door, find the switch, the key is manually called, the main power is switched to the standby power, and the panel indicator shows the backup power inputRestore the power supply to the automatic state, the key will be converted to the automatic state, and the power supply will be automatically switched to the main power.
5. Cut off the main power supply and check the backup power: find the main power switch in the dual power supply control cabinet, turn off the main power switch, and the indicator light on the control cabinet panel shows the backup power inputThen restore the main power switch, look at the control cabinet panel, and the indicator light shows the main power input.
6. Switch the control cabinet to automatic: observe the indicator light of the electrical control cabinet panel of the pressure increase (stabilizing) pump unit, and click the manual to switch to the automatic state.
7. Adjust the contact pressure gauge and check the start of the stabilizer pump: find the contact pressure gauge on the stabilizer pump, press the knob on the piezo contact pressure gauge, then rotate, turn the green pointer to the black pointer, the stabilizer pump will start automatically, turn the red pointer to the black pointer, the stabilizer pump will automatically stop, and finally restore the pointer position.
8. Manually start and stop the pump set on the electrical control cabinet of the pressure increase (stabilizing) pump set: press the manual switch on the control cabinet panel, press the X pump to start, the starting light is on, press the X pump to stop, the starting light is off, the start stop is normal, and the automatic state is restored.

Identification point 24: fire shutter operation
The specific oral answer is as follows:
Report to the examiner, there are seven ways to activate the fire shutter.
1. Lower, stop and rise through the manual button box, and open the manual lock before operation
2. Descend through the fire shutter controller;
3. Manually start the quick release device on site and pull the pull ring;
4. Mechanical emergency start mode, control the emergency guide chain to control the rise and fall of the fire shutter;
5. Through the temperature control release device, the temperature reaches 73 0At 5°, the glass bubble bursts, and the fire shutter automatically drops
6. Two independent temperature detectors in the fireproof partition are activated in linkage, and the fire shutter is lowered
7. Rely on the central control room, find the control button of the fire shutter on the bus reel to control the fire shutter down.

Identification point 27: elevator emergency landing operation
The specific oral answer is as follows:
1. Open the protective cover of the emergency landing button of the fire elevator model, check whether the power supply of the fire elevator is turned on, if not, turn on the power supply
2. Press the forced landing button, the fire elevator will be forced to land on the first floor or the conversion floor, and the elevator door will be opened for use
3. Press the button on other floors, and the fire elevator will not run;
4. Press and hold the door close button to close the door in the car, and press and hold the button for other floors, the fire elevator will run to the floor, and press and hold the door button to open the door
5. Turn off the forced landing button and reset the fire alarm controller.
