Flap barrier turnstiles are widely used in various access control scenarios, such as subway stations, office buildings, and shopping malls, due to their sleek design, fast passage speed, and high security. As a flap barrier turnstiles supplier, I have encountered numerous cases of turnstile failures over the years. Understanding these common failures is crucial for ensuring the proper functioning of the turnstiles and providing efficient after - sales service. In this blog, I will discuss some of the most prevalent issues that can occur with flap barrier turnstiles.
Mechanical Failures
Flap Movement Abnormalities
One of the most common mechanical problems is abnormal flap movement. The flaps may not open or close smoothly, get stuck halfway, or move too slowly or too quickly. This can be caused by several factors. Firstly, mechanical wear and tear over time can lead to loose or damaged components within the turnstile. For example, the gears that drive the flaps may become worn, resulting in uneven movement. Secondly, improper installation can also contribute to this issue. If the turnstile is not leveled correctly during installation, it can put extra stress on the mechanical parts, causing them to malfunction.
Another possible cause is the accumulation of dust and debris in the mechanical components. In high - traffic areas, dust, dirt, and small particles can enter the turnstile and interfere with the normal operation of the flaps. Regular maintenance, including cleaning and lubrication of the moving parts, can help prevent this problem. For instance, using a suitable lubricant on the gears and bearings can reduce friction and ensure smooth flap movement.
Flap Damage
Flap damage is another significant mechanical failure. The flaps can be damaged due to physical impact, such as a person pushing or hitting them forcefully. In some cases, objects may get caught between the flaps, causing them to break or bend. Additionally, environmental factors like extreme temperatures and humidity can also affect the durability of the flaps. For example, in areas with high humidity, the flaps may warp or corrode over time.
To address flap damage, it is important to use high - quality materials for the flaps. Some of our products, like the AFC Subway Turnstile Gate, are designed with durable and impact - resistant materials to minimize the risk of damage. In case of damage, prompt replacement of the flaps is necessary to restore the normal operation of the turnstile.
Electrical Failures
Power Supply Issues
A stable power supply is essential for the proper functioning of flap barrier turnstiles. Power supply problems can occur due to various reasons. Firstly, voltage fluctuations can damage the electrical components of the turnstile. In areas with unstable power grids, sudden voltage spikes or drops can cause the control board or other electrical parts to malfunction. Installing a voltage stabilizer can help protect the turnstile from such issues.
Secondly, loose or damaged power cables can also lead to power supply failures. Over time, the cables may become frayed or disconnected, resulting in a loss of power to the turnstile. Regular inspection of the power cables and connections is necessary to ensure a reliable power supply.
Sensor Malfunctions
Flap barrier turnstiles rely on sensors to detect the presence of people and control the movement of the flaps. Sensor malfunctions are quite common and can disrupt the normal operation of the turnstile. There are several types of sensors used in turnstiles, such as infrared sensors, proximity sensors, and photoelectric sensors.
Infrared sensors may fail due to dirt or dust covering the sensor lens, which can block the infrared signals. Proximity sensors can be affected by electromagnetic interference from nearby electrical devices. Photoelectric sensors may malfunction if there is a problem with the light source or the receiver. For example, if the light source is not emitting enough light, the sensor may not be able to detect objects accurately.
To troubleshoot sensor malfunctions, it is important to clean the sensor lenses regularly and check for any signs of damage. In some cases, recalibration of the sensors may be required. Our Smart Retractable Flap Barrier Turnstile is equipped with advanced sensors that are designed to be more reliable and less prone to malfunctions.
Software and Control System Failures
Control Board Problems
The control board is the brain of the flap barrier turnstile, responsible for coordinating the mechanical and electrical components. Control board problems can manifest in various ways, such as the turnstile not responding to commands, incorrect flap operation, or error messages on the display.
These problems can be caused by software bugs, hardware failures, or electrical interference. Software bugs may occur due to programming errors or compatibility issues with other systems. Hardware failures on the control board can be due to component damage or overheating. Electrical interference from nearby equipment can also disrupt the normal operation of the control board.
To address control board problems, it is important to have a professional technician diagnose and repair the issue. Regular software updates can also help fix bugs and improve the performance of the control system. Our Intelligent Pedestrian Turnstile Barrier Gate features a reliable control system that is continuously updated to ensure optimal performance.
Communication Failures
Flap barrier turnstiles often need to communicate with other systems, such as access control systems, ticketing systems, or monitoring systems. Communication failures can occur when there are issues with the communication protocols, network connectivity, or data transfer.
For example, if the turnstile is using a wireless communication protocol, interference from other wireless devices in the area can disrupt the communication. In a wired network, damaged cables or incorrect network settings can also lead to communication problems. Troubleshooting communication failures requires a thorough understanding of the communication protocols and network infrastructure.
Environmental and External Factors
Temperature and Humidity
Extreme temperatures and humidity can have a significant impact on the performance of flap barrier turnstiles. High temperatures can cause the electrical components to overheat, leading to malfunctions. In addition, the mechanical parts may expand or contract, affecting their normal operation. Low temperatures, on the other hand, can make the lubricants in the mechanical components thicker, reducing the smoothness of the flap movement.
High humidity can cause corrosion of the metal parts and short - circuits in the electrical components. In areas with high humidity, it is important to choose turnstiles that are designed to be resistant to moisture. Our turnstiles are tested under different environmental conditions to ensure their reliability in various climates.
Vandalism and Unauthorized Use
Vandalism and unauthorized use are also common problems in public areas. People may try to force the flaps open, damage the turnstile with tools, or use unauthorized access methods. To prevent vandalism, it is important to install turnstiles in a secure location and use anti - vandal features. For example, some of our turnstiles are equipped with alarms that can be triggered when there is an attempt at unauthorized access or vandalism.
