Operation method Henan fire door widely carries out publicity and education on the use, maintenance and management of fire prevention facilities within the jurisdiction of the fire department in charge, Efforts should be made to improve people's awareness of fire protection and self-protection; Extensive publicity, education and training on fire protection and umbrella protection knowledge shall be carried out for units installed with fire door maintenance, so as to make every employee understand the basic knowledge of the use, maintenance and management of fire door maintenance, and consciously participate in the maintenance and management of the Gate of Life, so as to keep them in a state of combat readiness at all times; The fire door maintenance purpose, function and good use status and basic requirements for use shall be posted on the fire door maintenance, and the words "normally closed fire door maintenance, please close at any time" shall be written on the conspicuous position of the normally closed fire door maintenance, so that customers and the masses can understand the basic knowledge of fire door maintenance. fire-resisting window direct deal Carry out publicity activities to protect fire-fighting facilities and equipment, and mobilize everyone to participate in the protection of fire-fighting facilities such as fire door maintenance.

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 fire-resisting window 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. fire-resisting window direct deal Pay attention to wearing the clothes in reverse (that is, the opening faces the opening).

The function effect of Henan fireproof rolling shutter door The fireproof rolling shutter door is based on the steel rolling shutter, the transmission parts are modified, equipped with fireproof electrical appliances and other equipment, so as to achieve the fireproof function: the fireproof motor is controlled by the fireproof electric cabinet, and the roller is driven by the speed change device to make the rolling shutter door open and close. In case of power failure, the manual handle on the fireproof motor can also be used to achieve manual operation. major fire-resisting window At the relative movement of the machinery, the coupling is used to replace the sprocket drive, and the friction in the track is inlaid with copper plate or nylon. fire-resisting window direct deal It is suitable for the use or storage of combustible gases, volatile chemicals and other high ignition materials in factories and warehouses where there is or may be an explosion of fire hazards. 1. The integrated bus is used internally, and the data transmission is reliable and fast. 2. It has the functions of phase sequence automatic detection, correction and phase loss protection. The standby power of main power supply can be switched automatically (with standby power). 3. With rich reserved interfaces, it can be linked with the fire control center. 4. All electronic learning and memory limit, no matter the upper limit or lower limit positioning will never change. 5. It adopts advanced microcomputer processor technology, which is stable and reliable, without upper limit height range 6. It has smoke and temperature sensing signal synchronization and step by step detection function. 7. The setting of operating parameters is simple, convenient and accurate. 8. It has the function of manual priority escape. In case of three-phase power or main power failure, the controller can automatically lower the roller shutter through the quick release device to close the roller shutter.

Maintenance methods and precautions of Henan fireproof door Maintenance methods and precautions of Henan fireproof door: 1. Door leaf and door frame shall be placed horizontally and stacked indoors with backing plates, and the frame and door leaf shall be stacked separately. 2. It is strictly prohibited to store together with acid-base substances. The room should be clean, dry and ventilated. 3. It shall be stored in the room with backup frame and separated from the heat source to avoid thermal deformation. 4. Try to avoid outdoor sunshine for a long time to prevent the fire door from being heated. 5. Keep the indoor air circulation and prevent the fire door from frequent damp. major fire-resisting window After splashing with water, wipe it with dry cloth to avoid local expansion. 6. To prevent the fire door from being hit abnormally, it is not advisable to use excessive force or open the door at an excessive angle. 7. It is not allowed to hit the door body with sharp tools and heavy objects to prevent the door body from being sunken, scratched and peeling off the paint film. 8.
