GS A221A Flap Barrier Turnstile Access Control System

GS A221A Flap Barrier Turnstile

Intelligent Access Control Solution for High-Traffic Projects

The GS A221A Flap Barrier Turnstile is part of GS Automatic’s Intelligent Passage Management System, designed to efficiently control pedestrian entry and exit in high-volume, security-sensitive environments.

With a standard lane width of up to 600 mm, the A221A supports uni-directional and bi-directional control, making it suitable for applications requiring both high throughput and controlled access.

🔹 Intelligent Passage Management

Compared with traditional manual control methods, the A221A significantly reduces manpower requirements while improving efficiency.

It enables accurate authorization, passenger counting, and passage control through integrated electronic and sensing technologies, supporting modern scientific management of pedestrian flow.

🔹 Robust Structure & Industrial Design

• Cabinet manufactured from Stainless Steel AISI 304

• Internal structure with reinforced stainless steel frame

• Retractable rubberized flap barriers for safe pedestrian passage

• Elegant appearance, corrosion-resistant, and durable for long-term use

🔹 Advanced Control & Safety Features

• Infrared sensing for real-time passage monitoring

• Anti-tailgating and intrusion prevention

• Audible alarm (visual alarm optional) for illegal entry

• Automatic flap retraction in case of power failure or emergency

• Integrated fire alarm interface to ensure safe evacuation

🔹 Flexible Operating Logic (Integrator Friendly)

• Normally Open (NO) and Normally Closed (NC) modes

• Adjustable barrier opening speed based on passenger flow

• Configurable passage direction and operating modes

• Timeout reset function for incomplete passages

• Card reading with or without memory option

🔹 Seamless System Integration

Equipped with standard input/output interfaces, the A221A allows easy integration with:

• RFID / IC / ID card systems

• Barcode and QR code readers

• Automatic Fare Collection Systems (AFCS)

• Integrated Transport Management Systems (ITMS)

• Centralized access control and monitoring platforms

🔹 Lane Configuration Options

• Single lane

• Double lane

• Triple lane

• Multi-lane (tandem / modular layouts)

The system supports strong expansion capability, allowing additional lanes or passage types to be added without affecting overall system performance.

🔹 Typical Applications

Metro and railway stations, airports, stadiums and arenas, commercial buildings, retail crowd control, amusement parks, perimeter and interior security, transit fare collection systems, and lobby access control.

🔧 Technical Specifications

Specifications may vary depending on single-core or double-core configuration.
