Section 1 indoor fire hydrant use and maintenance
Indoor fire hydrant is a fixed fire extinguishing water supply equipment and buildings. It includes a fire hydrant and fire box.
An indoor fire hydrant and indoor fire box
Indoor fire hydrant and indoor fire box is usually located in the stairwells, corridors and interior walls. Inside the hose, water cannons and fire hydrant export connections, fire hydrant and fire water supply pipeline to connect the building. A fire occurs, turn the hand opening direction of the wheel, the water gun jet out of the water.
(A) indoor fire hydrant
Indoor fire hydrant by the hand wheel, bonnet, stem, body, seat and interface components.
When using an indoor fire hydrant, open the fire hydrant box, remove the hose and water cannons, fire hydrant valve handwheel opening direction of rotation can fire-fighting water.
Usual maintenance should be noted:
1, regularly check indoor fire hydrant is in good condition, with or without rust, water leakage;
2, check the interface gasket is intact;
Fire hydrant on the stem should be filled with oil;
4, regular water checks to ensure that the open water when the fire broke.
(B) of the fire box
The hydrant box is to place the equipment to cabinet of the indoor fire hydrant, water guns, hoses and electrical control button, the installation and the building, according to the requirements of the embedded wall installation can also be hung on the wall.
Indoor fire hydrant box, the door open with a key to open the door or shattered glass, twist the lock open, such as the elimination or tied with "emergency knob, should be ring-pull and pull outward , and then clockwise to turn the knob to open the door. Open the door, remove the water gun, press the pump start button, rotate hydrant handwheel, to open the hydrant, laying of water to set up water.
Maintenance of the fire box should note the following:
, Fire fighting, we should water with dry cleaned, coiled or folded in the box, and then the water gun card clip in the gun, installed lock boxes for a good glass, close the door.
, Regularly check the fire box door is damaged, the door locks open and flexible, pull-ring seals whether the loss of the ring is intact, water with dial framework cabinet corrosion. Identify problems, timely replacement and repair.
Section II automatic fire alarm equipment use and maintenance
Automatic fire alarm equipment, buildings, especially high-rise buildings and important buildings essential fire-fighting facilities. Therefore, the automatic fire alarm equipment once operational, it is necessary to strictly manage.
The entire system must be by the person responsible to adhere to the duty day and night system. Unrelated persons are not free to touch, and ensure that all of the system is in normal operation.
A maintenance and management staff must do the following:
On duty automatic fire alarm arrangement of parts of the system's alarm and fire custody places the unit should be clear.
Equipment put into regular use, to ensure reliable operation, must be in strict accordance with the system of regular inspections to check.
Checked daily: by checking the device, check the fire alarms each function (such as fire function, fault function) are normal, with or without light damage.
Weekly inspections: main, backup power supply automatically converted to the test.
Every six months to check the effectiveness of simulation tests, the failure of fire detectors should be replaced: all fire detectors; cable, junction boxes, equipment for visual inspection, cleaning up the dust.
Automatic fire alarm device of continuous uninterrupted operation, the value false positive reasons are more complex, so the alarm device emits a small amount of false positives is inevitable, so ask the duty officer receiving the alarm, you should silencer and rushed to the scene, to be determined fire fire-fighting measures be taken to start the external control fire extinguishing installations, report to the fire department and competent leadership.
Second, the automatic fire alarm equipment troubleshooting
Automatic fire alarm equipment, circuit complexity, the higher technical requirements, and the production structure of the factory product, the line running to differ materially, more the type of fault, in addition to the common failure, the automatic fire alarm equipment maintenance should be The maintenance staff is responsible for repairs.
Automatic fire alarm equipment, common faults and their inspection methods are:
Main power failure: Check the input power is intact, melting wire with or without blown and poor contact.
Standby power failure: check the charging device, the battery is damaged, connect with or without break.
Is in good condition detection circuit fault: check the wiring of the loop fire detectors, fire detectors with or without being removed, the terminal monitor for damage.
False alarm of fire: the interference of the detection area of the check fire detectors with or without steam, dust and other fire detectors work properly exist, if interference exists, you should try to exclude.
Frequent false alarms without interference and affect the normal work of fire detectors should be replaced in a timely manner.
Temporary rule out a fault that can not, shall immediately notify the relevant professional maintenance units, in order to resume normal work as soon as possible.
