The advantages and problems in the development of fire doors in Henan Province Fire doors are more popular in recent years, so how much do you know about the maintenance, advantages and development of fire doors? The following section will provide you with a comprehensive knowledge of fire doors, so that you can better understand fire doors. major Refuge bay door Fireproof door is a kind of movable fireproof partition. In addition to the function of ordinary door, it, together with the frame, can meet the requirements of fire resistance stability and integrity within a certain period of time. It has special functions of fire prevention, smoke separation and high temperature blocking. In case of fire, it should have self closing and signal feedback functions. （1） Advantages of fire doors In case of fire, Henan fire doors and windows can be automatically closed through the linkage control system when they are in the open shoulder state, effectively ensuring the reliable closing of fire door maintenance in the fire, so as to achieve its due role in smoke separation and fire resistance. There is no big difference between the maintenance of fire doors and the maintenance of normally closed fire doors in terms of production and basic configuration, but the door closers for the maintenance of normally closed fire doors are replaced with automatic fire release devices that are linked with the automatic fire alarm. At the same time, they can be installed with the control box produced by the manufacturer. Linkage is achieved by installing smoke detectors and smoke detectors on the left and right sides of the maintenance of fire doors, When the smoke detector detects the smoke signal and sends it to the host computer of the automatic fire alarm linkage control system, the linkage control system transmits 24v power to the fire door maintenance releaser to automatically close the fire door for maintenance. The closing or opening status of the fire door maintenance has signals fed back to the alarm host computer or control box. Refuge bay door direct deal The automatic release device for fire door maintenance developed by Dong Shicong of Chengdu Huili University Research Institute can open the fire door maintenance for 0-180 degrees freely and close it smoothly, completely changing the disadvantage of inconvenient use of the normally closed fire door maintenance closer due to its large opening angle of 90 degrees, and once the fire door is closed for maintenance, the release device will not be reset, It has become a movable fire door maintenance that automatically opens, closes, opens and closes, overcoming the contradiction that normally closed fire doors must be manually closed or cannot be closed after being pushed to a certain limit (greater than 90 degrees) for maintenance; The lesson of blood proves that people who escape from a fire simply cannot close the opened fire door for maintenance due to panic and eagerness to escape.

Henan fireproof rolling shutter door maintenance common faults and treatment methods The fireproof rolling shutter door is constantly applied to large supermarkets, shopping malls, underground garages, workshops and other crowded places. It is inevitable that there will be some small problems that need to be solved. I summarize a few points for your reference. 1、 The fire shutter door does not act: first, check the power supply to see if the power supply air switch of the fire shutter door has power. 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. In case of open circuit or short circuit, check whether the motor brake is burnt or whether the spare board is burnt. 3、 The operation button does not work properly: you should first press the Stop key, then press the Reset key, and then press the Up and Down keys. 4、 The indicator lights of the power control box or button panel are all on: at this time, first check whether there is a short circuit in the button line or a button may be pressed to death. If the above phenomenon does not exist, it may be that the chip on the power main board is broken, and then replace the chip.
