What are the causes of fire safety problems?
The main functions of the systemWhen the fire breaks out, the detector sends the fire signal to the alarm controller, which is displayed by the acoustooptic signal, and shows the place of the fire on the control panel, so as to predict the fire. At the same time, you can also use manual alarm button to complete manual alarm function.
system composition(1) control device: smoke detector, temperature detector, flame detector. (2) manual alarm device: manual alarm button.(3) alarm detector: regional alarm, centralized alarm, control center alarm.
1. The system comprises a fire pump, a stabilizing pump (or a pressure stabilizing tank), a fire hydrant box, a hydrant valve, an interface water gun, a water hose, a fire hydrant, an alarm button, a fire hydrant system and a control cabinet.2, the main function of the system, fire hydrant system pipes filled with pressure water, such as the system has a trace of leakage, you can rely on the pressure regulator pump or tank to maintain the system of water and pressure. When the fire hydrant box, first opened, according to the requirements of connected interface, hose, gun at the fire hydrant valve open, water immediately with water spray, press the fire hydrant button, through the fire hydrant to start the fire pump to supply water to the pipeline. 3, the system prone problems, causes, simple treatment(1) open fire hydrant valve without water. Reason: there may be leaks in the pipe, the pipe is not water, and the pressure gauge is damaged and the voltage stabilizing system doesn't work. Treatment method: check the leak point, pressure gauge, repair or install voltage stabilizing device, to ensure that the hydrant has water.(2) press the manual button, can not linkage start fire pump. Reason: manual button wiring is loose, the button itself is damaged, the linkage control cabinet itself is faulty, the fire pump starts the cabinet trouble or the connection to be loose, the fire pump itself is faulty. Processing method: check each equipment wiring, equipment itself, check the pump itself, electrical, mechanical parts of the fault, and ruled out.
The system is prone to problems, causes, and simple handling methods(1) detector malfunction alarm, detector fault alarm. Reasons: unreasonable detector sensitivity, excessive ambient humidity, excessive wind speed, excessive dust, mechanical vibration, long detector usage, and decreased device parameters. Treatment method: according to the installation environment, choose the appropriate sensitivity of the detector, installation should avoid the wind and wind speed larger channel, regular inspection, according to the conditions of cleaning and replacement detector.(2) manual button false alarm, manual button fault alarm. Reason: the button used for too long, the parameter drops, or the button artificially damage. Treatment method: regular inspection, timely replacement of damage, so as not to affect the operation of the system.(3) alarm controller failure. Reason: the device itself is damaged, failure or external detector, manual button problem caused alarm controller failure, fire alarm. Treatment method: use table or own diagnosis procedure to judge the machine itself, troubleshooting, or according to (1) (2) processing method, check whether the fault caused by the outside world.(4) line fault. Reasons: insulation damage, loose joints, environmental humidity is too large, resulting in insulation decline. Processing method: check the insulation degree with the meter, check the connection condition, welding process, plastic sealing process and so on.
