The advantages and disadvantages of the products of Henan fire rolling shutter manufacturers The fire rolling shutter is usually located at the poor entrance of the building, which plays a role in fire prevention, heat insulation and smoke dispersion. The fireproof rolling shutter door is a useful time to isolate the fire source when a fire occurs and provide a useful escape for employees. major Refuge bay door However, the inferior fire rolling shutter door will not only not intercept the fire source, but also increase the fire. Therefore, the advantages and disadvantages of the fire rolling shutter door are also quite important.

If there is no power, check the power supply. If there is power, the power indicator of the roller shutter control box should be green at this time. major Refuge bay door If the indicator light is not on, then we should check whether the transformer in the control box (the resistance of the transformer is 270 ohms) is burned out. If the power indicator flashes green, it indicates that the power supply may be out of phase. If the power supply is not out of phase, it may be that the standby power board of the control box is burned out; It is also possible that both the power board and the standby power board are burned out. 2、 Henan fire shutter door power supply air switch cannot be pushed up: when delivering the gate, the air switch cannot be pushed up, first check whether there is a problem with the standby board, and the resistance of the output line of the standby board is about 300 ohms.
