GS G535-2 Tandem Full Height Turnstile (Twin Lanes) for Perimeter Security

GS G535-2 Tandem Full Height Turnstile

Twin-Lane High-Security Perimeter Access Control Solution

The GS G535-2 Tandem Full Height Turnstile is a twin-lane (double passage) pedestrian access control system designed for high-security perimeter applications where increased throughput and space efficiency are required.

By integrating two full-height lanes into one modular structure, the G535-2 provides higher pedestrian capacity while maintaining the same high level of security as a single-lane full height turnstile. It is especially suitable for industrial facilities, infrastructure projects, and EPC deployments.

🏗️ Tandem / Twin Lanes Modular Structure

• Two independent full-height lanes integrated into one unit

• Outer cage with vertical and “U” bar sections

• Central rotating columns with 3 × 120° offset U-bar configuration

• Modular design allows easy on-site assembly without heavy lifting equipment

• Designed for direct installation on concrete surfaces

• Optional foundation frame available for paved areas

🔐 High-Security Bi-Directional Access Control

• Each lane supports bi-directional pedestrian control

• • Free access

  • Permanently locked

  • Locked with fail-safe or fail-secure option

  • Electrically controlled (authorization-based passage)

    Multiple configurable operating modes per direction:

• Automatic relocking if no passage occurs within 20 seconds after authorization

🔗 System Integration & Communication (Integrator Friendly)

• Input signal: Dry Contact

• Additional interface: RS485 serial port

• Communication distance up to 1200 meters

• Output signals available for access control systems and remote counting

• Easy integration with:

  • RFID / IC / ID card readers

  • Biometric systems (fingerprint, face recognition)

  • Push button consoles

  • Central security management platforms

  📌 Customer-supplied readers can be surface mounted on the turnstile cage via dedicated mounting plates.

🚨 Emergency, Fire & Safety Functions

• Automatic unlocking or free rotation in case of emergency or power failure

• Fire control interface for integration with fire alarm systems

• “Attendant Override” input allows manual bypass of access control

• Field activation test buttons for local functional testing

🛠️ Heavy-Duty Materials & Outdoor Durability

• All steel components hot-dip galvanized after fabrication

• Optional powder coating in RAL 7042 grey

• Designed for harsh outdoor environments

• Protection level: IP65

🏢 Typical EPC & Project Applications
