GS A203 Optical Turnstile Speed Gate Access Control System

GS A203 Optical Turnstile

High-Throughput Speed Gate for System Integrators & EPC Projects

The GS A203 Optical Turnstile, also known as a Speed Gate, is designed to control pedestrian entry and exit in restricted and semi-restricted areas where high throughput, access control integration, and anti-tailgating protection are required.

Equipped with ultra-quiet retractable acrylic wings, a precision DC motor drive, and advanced optical sensor technology, the A203 ensures smooth pedestrian flow while effectively preventing unauthorized access.

🔍 Optical Anti-Tailgating & Safety Technology

• Multiple infrared optical sensors detect pedestrian movement in real time

• Prevents tailgating, reverse passage, crawling, and illegal entry

• Built-in alarm activated on unauthorized passage attempts

• Double protection design minimizes misuse in high-traffic environments

🔺 Retractable Acrylic Wing Structure

• Passage blocked by triangular retractable acrylic glass wings

• Wings retract fully into the housing after authorization

• Passage becomes completely unobstructed

• Adjustable opening and closing time: 0.8 – 1.5 seconds

• Soft wing design minimizes injury risk and improves tailgating prevention

🚦 LED Direction & Status Indication

• 90 mm diameter LED indicators flush-mounted on the top lid

• Green arrow: authorized passage direction

• Red cross: passage locked or lane in use

• Improves pedestrian guidance and operational clarity

🚨 Emergency, Fire & Fail-Safe Operation

• Power failure: wings automatically open for free exit

• Fire alarm interface: voltage-free contact supported for fail-safe mode

• Designed to meet public safety and evacuation requirements

🔄 Flexible Operating Modes (Integrator Friendly)

• One-way card reading / one-way no entry

• Two-way card reading

• One-way card reading / one-way free passage (with or without push button)

• Two-way free passage (with or without push button)

• Auto reset if no passage within valid card-reading time

🔗 Access Control Integration
