In order to prevent the travel switch from malfunctioning, the roller shutter from jamming, the motor from being blocked and other accidents. The steel fire shutters of the fireproof partition and the fireproof partition are not used frequently, and the roller shutter should be effectively put into use once a fire breaks out in the area.

The automatic control fire shutter with linkage control and control center control must be carried out according to a set of control command procedures. In the process of use, once an abnormal situation is found, emergency measures should be taken immediately to cut off the input power supply and eliminate the fault. A regular maintenance system should be established for fire shutters, and the maintenance records of each roller shutter should be recorded, and recorded.

The roller shutter that does not open and close for a long time must be maintained once every six months, and the content is to eliminate dust, paint, and add lubricating oil to the sprocket roller chain of the transmission part. Check whether the electrical wiring and electrical equipment are damaged, whether the operation is normal, whether it can comply with the instructions, if there is damage and do not meet the requirements, it should be repaired immediately. Installation requirements and instructions for the use of fire shutter doors, the upper part of the opening for installing the shutter door shall not be equipped with ventilation pipes, water pipes, etc.; The power supply line (three-phase five-wire and fire central control signal line) is laid by the user to the side of the electrical control box next to the rolling door machine; After the roller shutter door is installed, install the ceiling, and the edge of the ceiling should be 50mm away from the curtain plate to avoid friction; When debugging and using, it is strictly forbidden to stand at the bottom.

Electrical facilities shall not be dismantled without authorization; According to the fire management regulations, the fire shutter door is a special fire protection facility, which shall not be used for other purposes, and no items shall be stacked directly below the shutter; After installation and commissioning, it is started once a quarter to check the electrical and mechanical properties, and pay attention to the safety of operation during inspection.

Summary. There are four ways to open a fire shutter door:

Manual on, where manual on is often used in the event of a power outage.

Strong power to open, strong power to open is to directly press the roller shutter switch button by hand.

Weak current is turned on, weak current is controlled, and the signal is fed back to the control box by the fire alarm control system.

Single weak current, single weak current open, can be turned on in both directions, can be manually controlled in case of fire.

Thank you! Precautions for the use of fire shutter door 1, before opening and closing the fire shutter door, first look at whether there are obstacles under the fire shutter door, if so, to remove the obstacles in time. 2. When the fire shutter door is in operation, it is strictly forbidden to stand or walk around below.

If there is an abnormal sound of the door body or motor, press the emergency stop button quickly, and cut off the power supply to stop the fire shutter door. 3. When the power supply of the fire shutter door is turned off, the door body needs to be closed manually. 4. When the rolling shutter door is lowered, pull down the pull rod at the tail of the motor, the rolling shutter will slowly and uniformly descend, and when the rolling shutter is about to close, pull the handle again until it is all closed.

5. If you want the fire shutter door to rise, you can pull the hand pull chain. During the operation, it should be noted that the fire shutter door should not be opened and closed by manual and electric at the same time.

Thank you! You're welcome dear.

As one of the main fire protection products in our lives, fire shutter doors play a very important role. So what are the functions of fire shutter doors? Let me explain it to you. Hope it helps.

What is a fire shutter door.

The fire shutter door is composed of a curtain plate, a reel, a motor, a guide rail, a bracket, a protective cover and a control mechanism together with the roller shutter whose frame can meet the requirements of fire resistance stability and integrity within a certain period of time. The fireproof roller shutter is mainly used for the wall that needs to be fireproofed, especially when the firewall and fireproof partition wall need to open a large opening due to production and use, and the fireproof door cannot be set up.

What does a fire shutter door do? 1. The internal integrated bus is adopted, and the data transmission is reliable and fast.

2. It has the functions of automatic detection, correction and phase loss protection of phase sequence. The main power backup power can be automatically switched (with backup power).

3. It has a wealth of reserved interfaces, which can be linked with the fire control center.

4. The all-electronic learning and memory limit is absolutely accurate, and the positioning of the upper or lower limit will never change.

5 Using advanced microcomputer processor technology, stable and reliable, no upper limit height range limit.

6. It has the function of synchronous step-by-step detection of smoke temperature sensing signal.

7. The setting of operating parameters is simple, convenient and accurate.

The fire shutter does not have the control mode of automatic lifting, and can only fall automatically, not automatically rise. At present, there are four control methods for fire shutters.

1. Manual control, often used in power failure. The manual start of the fire shutter is to press the button, pull the manual chain, and open the brake.

2. Strong current control, hand press the roller shutter switch button control, is the most commonly used control method.

3. Weak current control, in places with fire control rooms, fire linkage control of the alarm system in the event of a fire.

4. Single weak current control, through the smoke and temperature sensing device and the roller shutter linkage, so as to achieve automatic control.

1. Limit the number of fire shutters in fire protection zones:

The greater the number of fire shutters in the same fire protection zone, the lower the reliability of the overall fire shutter, so the fire shutter of the fire protection zone should be controlled.

For places with special needs, it is necessary to set up multiple fire shutters, and other measures should be taken to enhance their reliability, or to conduct performance assessment to achieve the equivalent level of fire safety and safety.

2. Limit the application scope of fire shutters

In addition to the firewall in the warehouse, the firewall can not be replaced by a fire shutter, and the firewall can be replaced when it is difficult to set up. In view of the widespread problem of low reliability of fire shutters, it is recommended that the technical specifications for the application of fire shutters be revised. It should be made clear that fire shutters cannot replace firewalls, and strict regulations should be made on the application sites and parts of fire shutters.

3. Increase the fire shutter anti-blocking alarm function

The fire shutter is more common in the use of the rough carrying of the article in the case of the situation, accounting for 40% of the fault causes, although there are personnel patrols in the management measures, the site has a sign prohibiting stacking items under the shutter, but due to the ** and logistics mountain model is dynamic, the fire shutter may be blocked by the item at any time, once a fire occurs at this time, the fire shutter can not effectively land, can not play the role of fire separation.
