　　②in the terminal, simulation of fire control equipment and input / output module connection circuit, short circuit fault and a stopwatch, check the sound and light alarm. 

　　③remote manually start the linkage control of fire equipment, view the transmission of control signals. 

　　4）return to normal alert. 

　　detection method of fire hydrant system 

　　1）the worst fire hydrant selection, connect the pressure gauge and cap, open fire hydrant, hydrant hydrostatic pressure measurement.

　　2）connect the hose and a water gun, start the fire pump, check the fire pump start and signal display, measurement of hydrant hydrostatic pressure.

　　3）according to the design of open water hydrant, hydrant water pressure measurement at the most unfavorable point. 。

　　4）according to the design of open water hydrant, hydrant water pressure measurement at the most favorable. 

　　5）system restore normal state 

　　detection method of automatic sprinkler system 

　　method for detecting wet system 

　　1）open the most unfavorable place at the end of the test device, check the pressure gauge display; check the flow indicator, pressure switch and fire pump action and feedback signal. 

　　2）measure the time from the open end of the test device to the fire pump operation.

　　3）with a sound level meter to measure the hydraulic alarm ring strong value. 

　　4）system return to normal. 

　　detection method of dry system 

　　1）open the most unfavorable at the end of the water test device control valve, check the flow indicator, pressure switch and fire pump, electric valve action and feedback signal, as well as the exhaust valve exhaust. 

　　2）measure the time from the open end of the test device to the outlet pressure of 0.05mpa. 

　　3）system return to normal. 

　　detection method of pre action system 

　　1）two fire detectors have been triggered in the protection area, to see the solenoid valve, electric valve, fire pump and water flow indicator, pressure switch action and feedback signals, as well as the exhaust valve exhaust. 

　　2）after the alarm 2min open the end of the test device to measure the water pressure. 

　　3）with a sound level meter to measure the hydraulic alarm ring strong value.

　　4）system return to normal. 

　　detection method of deluge system 

　　1）the system is arranged in parallel multiple deluge valve, check valve and control logic. 

　　2）has triggered two fire detectors in the protection area or pressure relief for the transmission pipe, check the solenoid valve, fire pump and pressure switch action and feedback signal. 

　　3）with a sound level meter to measure the hydraulic alarm ring strong value. 

　　4）not the actual water place, should close the deluge valve outlet control valve before test. 

　　5）system return to normal. 

　　detection method of evacuation indicator 

　　1）view the appearance and location, check the direction 。
