What is a Double Turnstile Unit?

A Double Turnstile Unit consists of two synchronized turnstile mechanisms positioned side-by-side, allowing two people to pass simultaneously in either direction. The main purpose of this configuration is to manage high pedestrian traffic without compromising security. The design allows for fast entry while ensuring that unauthorized individuals are prevented from bypassing the access point.

These units are typically used in high-security areas or high-traffic locations where controlling the flow of people is essential. Double turnstiles are not just security barriers; they serve as key components of access control systems, helping businesses and institutions maintain safety while streamlining entry processes.

Key Features of a Double Turnstile Unit

1. Dual-Lane Design for Efficient Traffic Flow
   • The dual-lane design of the Double Turnstile Unit enables two individuals to pass simultaneously, significantly improving people throughput. This is particularly advantageous in busy locations where high volumes of pedestrians need to be processed quickly, such as in transport hubs, stadiums, and event venues.
   • The simultaneous access reduces waiting times and enhances the efficiency of entry and exit, preventing bottlenecks that can occur in single-lane systems.
2. Bidirectional Movement
   • The Double Turnstile Unit allows for bidirectional movement, meaning people can pass through in both directions: entering or exiting a facility. The turnstile arms can be programmed to open in one direction only or allow for two-way passage based on security requirements and traffic flow.
   • In environments like subways, airports, and concert venues, this feature enables more flexible management of crowd movement, allowing operators to control the direction of access based on the time of day or specific events.
3. Integration with Access Control Systems
   • One of the most significant advantages of the Double Turnstile Unit is its compatibility with a range of access control systems. This includes integration with RFID, biometric scanners, barcode scanners, QR code readers, and ticket validation systems.
   • These systems can be used to ensure that only authorized personnel or ticket holders can pass through the turnstile. For example, a RFID card reader could verify an employee’s credentials, while a barcode scanner could validate a concert ticket. The system can also include contactless access for improved user experience.
4. Emergency Override Mechanism
   • Safety is a top priority, and Double Turnstile Units are designed with emergency override mechanisms that allow the turnstile arms to open freely during emergencies, such as evacuations. This ensures that people can exit the premises swiftly and safely without being hindered by security barriers.
   • The emergency mode is often activated automatically in case of power failure, or it can be manually triggered by authorized personnel.
5. Sturdy and Vandal-Resistant Construction
   • The construction of Double Turnstile Units is typically heavy-duty, made from stainless steel or aluminum, offering both durability and resistance to vandalism. These materials are ideal for high-traffic environments where frequent use and potential external impacts are common.
   • The turnstile arms are designed to resist damage from attempts at forced entry or vandalism, and the entire unit is typically designed to be tamper-proof to ensure the security of the access point.
6. Compact and Space-Efficient
   • Despite accommodating two users simultaneously, a Double Turnstile Unit maintains a compact footprint. This makes it an ideal solution for installations in areas where space is limited, such as narrow hallways, entrances to smaller buildings, or crowded venues.
   • The unit can be installed as part of a larger access control system or used independently, providing flexibility in design and setup.
7. Modern User Interface
   • Many Double Turnstile Units are equipped with a user-friendly interface, including LCD screens and visual indicators. These features provide clear instructions and visual cues to users, such as green lights indicating access is granted and red lights signaling restricted access.
   • The user interface may also include audio cues or voice prompts to help users understand the process, especially in areas where high volumes of people pass through.
8. Energy-Efficient Design
   • Modern Double Turnstile Units are designed to be energy-efficient, often incorporating low-energy motors and smart sensors. This reduces the overall operational costs, making them suitable for both temporary and long-term installations.
   • Additionally, many units feature automatic power-off features, ensuring that energy consumption is minimized when the turnstile is not in use.
