5. view the indoor hydrant logo, box, component and container; the same building you should adopt the uniform specifications for fire hydrants, fire-fighting water gun and fire hose; view for fire protection design position.

6. view the fire hydrant Kai pump button appearance and accessories; trigger button, view the fire pump start, the button to confirm the lamp and the feedback signals.

7. view the fire monitor look, go to view entry handwheelControl valves; human action fire cannons, viewing angle of the Rotary and back down and locate agencies.

6 system function check test

1, fire pump start function test. The fire pump should start running each month once, internal combustion engine driven fire pump should start running per week. When the fire pump to automatically control startup, monthly simulation and automatic control of conditions to start running again.

2. fire hydrants testing for fire protection design hydrostatic pressure checks. Checking method: test with pressure gauge connection at the fire hydrant equipment exports, opening fire hydrant valve, the pressure on the pressure gauge observation. Standard for fire protection design pressure required: fire hydrant should meet the design requirements, and should not be greater than 1.00MPa.

3, fire hydrant outlet pressure inspection test for fire protection design. Checking method: test with pressure gauge and fire hose, fire nozzles connected to the fire hydrant outlet opened fire hydrant valve, water, observation of pressure gauge pressure value. Standard for fire protection design outlet pressure: fire hydrant should meet the design requirements, and should not be greater than 0.5MPa, such as greater than, the fire hydrant Office should be set and vacuum unit.

6, the fire pump room scene starts fire pump check test. Each quarter, ought to at least one the following inspection and test. Action steps, methods: first, view the fire pump room is set up the phone, fire, emergency lighting, fire pump control switch is set to automatic. The second is in the fire pump control cabinet manual fire pump start-up and shutdown button, observe the fire pump action and control room fire control equipment signal display, use the stopwatch test fire pump start running time. Check the standard requirements: first, the fire pump room should be set fire emergency lighting, sets and fire control rooms direct contact of communications equipment, fire hydrant control cabinet switch should be set to automatic. Second, the fire pump start-up and shutdown functions properly, it should be in the 60S in input correctly, and to control room fire control equipment feedback signal its movements.

7, control room remote start fire pump check test. Each quarter, ought to at least one the following inspection and test. Action steps, how to: control room fire control device and manually direct control unit respectively manual fire pump start-up and shutdown button, observe the fire pump action and fire control devices start signal display, use the stopwatch test fire pump start running time. Fire control equipment should be able to receive and display the pump action signals.

8, fire hydrant buttons restart pump function check test. Checking method: start a fire hydrant button, observe whether actions, pump control room fire control equipment is emitting sound, light and alarm signal and displays its position. Standard requirements: fire hydrant button starts, its led should be dimmed light, the light is red, indoors light conditions, distance 3 metres distance should be clearly visible.

9, voltage test system function check. Each quarter, ought to at least one the following inspection and test. Action steps, method: simulation of voltage pump design start cap pressure and lower pressure guages, observation to lower pressure value, regulators pumps can immediately start; to limit the pressure value, regulators pumps can stop running. Test standard: when the system is less than the minimum design pressure regulators pumps should start immediately, when the system pressure, regulators pumps should automatically stops running.

7 system maintenance

1. each of the corresponding headwaters of water supply capacity to carry out a determination; fire water tank, fire water tank and fire-pressure water sharing equipment should be checked once a month, and you should check the water level and fire fire-reserve pressure water sharing equipment of the gas pressure.

2, fire water tank, fire water tank and fire-pressure water sharing equipment of water should be based on the local environment and climate conditions are changed regularly.

3, the cold season, fire water storage devices are not allowed on any part of the ice. Every day you should check the setting of water equipment room, keeping the room temperature is not lower than 50C.

4. every two years should fire water storage device for inspection, repair of defect and repainting.

5. steel fire water tank and fire-pressure water sharing equipment glass water level gauge, at both ends of angle without water level observation should be closed.

6. system control valve on all should adopt lead seals or chains in the State of the opening or fixed. Each month the chains should lead seals, a check, when there are corrupted or damaged shall promptly repair replacement.

Article 8 monitoring display requirements

Fire control rooms should be able to show the fire pump power for operation. Should be able to display a system's fire pump start-up and shutdown status and fault status and can show the fire hydrant button work status, physical location, fire water tank (pool) level and pipeline pressure alarm, etc. Should be automatic and manual control fire pump start-up and shutdown, and can receive and display the feedback signal fire pumps.
