What are the key points of fire protection acceptance of fire water system?
1. Fire water supply
(1) Check the nature of the fire water source, the number and diameter of the water inlet pipes and the setting of the fire pool;
(2) Check the volume of the fire pool, the water level indicator and the water replenishment facilities, the pressure stabilization facilities, the guarantee of fire water and antifreeze measures, etc.;
(3) Check the setting, volume, antifreeze measures, water replenishment and check valve condition of the fire water tank;
(4) Detect the performance of various fire pumps, pipelines, manual automatic control, start-up time, main and standby pumps and main and standby power conversion functions, etc.;
(5) Detecting the setting, marking and function of transporting fire-fighting water of the water pump coupler;
(6) Detect the fire stabilizer pump and its automatic pressure maintaining function.

2. Fire hydrant system
(1) Check the installation, components, specifications and spacing of indoor fire hydrants;
(2) Detect the setting of roof fire hydrants, the measures for freezing and the length of the water column, etc.;
(3) Check the setting, diameter and color of the indoor fire hydrant pipe network, ensure the fire fighting water and its connection shape;
(4) Detect the static pressure, dynamic pressure and the length of the full water column of the first floor and the most unfavorable point of the indoor fire hydrant;
(5) Check the setting and function of the manual pump start button (direct pump start, signal response);
(6) Check the configuration of the outdoor plug and check the length of the full water column of the outdoor plug;
(7) Check the configuration of the fire extinguisher, etc.

3. Automatic water spray (mist) fire extinguishing system
(1) Check the installation and connection of the pipe network, the number of nozzles and the diameter of the end pipe, etc.;
(2) Check the installation and function of the water flow indicator and signal valve;
(3) Detect the installation of the alarm valve group, the status of the valve, the components and their functions;
(4) Detect sprinkler installation, appearance, protection distance and protection area and distance from adjacent obstacles, etc.;
(5) Carry out functional test on the alarm valve group;
(6) Carry out the functional test of the automatic spray water (mist) system (start the pump at the end and start the pump with the alarm drain valve).
