AB Interlocking Turnstile Door
IM.HF.02
The High-Security AB Interlocking Turnstile Door System is an advanced access control solution designed for facilities requiring strict, single-person entry verification. With biometric authentication, anti-piggybacking protection, and dual-door interlock control, it ensures only one authorized user passes at a time.Integrated with a 3D depth-sensing camera, the system scans the chamber to detect multiple individuals and identify any left objects or suspicious items, enhancing real-time security accuracy.Ideal for data centers, financial institutions, government buildings, laboratories, airports, customs, and other high-security environments.

The AB Interlocking Turnstile Door delivers high-level access control through a dual-door interlock system. It helps secure sensitive areas like data centers, banks, government offices, laboratories, and border checkpoints by allowing only one person to pass at a time with verified credentials.
Unlike traditional gates, this system uses two sequential doors—Door A and Door B—to form a secure passage zone. A user must fully pass through and close the first door before the second one opens. As a result, it prevents tailgating, piggybacking, and forced entry attempts. This secure zone combines physical restriction with intelligent detection for complete access control.
Features:
- Dual-door interlock mechanism enforces one-door-at-a-time access
- Infrared or weight sensors detect single-person entry
- Supports multi-factor authentication: RFID, biometrics, QR, or PIN
- Built-in logic triggers alarms during tailgating or piggybacking attempts
- Optional bulletproof or impact-resistant glass for high-risk installations
- Seamless integration with fire alarms and emergency release systems
- Available in stainless steel or powder-coated frames with tempered glass doors
- Configurable fail-safe or fail-secure mode for emergency compliance
- Customizable passage size and user flow rate
- Auto-locking after each authorized or denied access attempt
Facility managers can configure the system for entry-only, exit-only, or bidirectional operation. The modular structure fits standalone use or integrates with cleanrooms, secure lobbies, or staff checkpoints. Furthermore, audio and visual prompts guide users during the process, while the system logs each event in real time for audit and compliance tracking.
The AB Interlocking Turnstile resists tampering and physical manipulation. Because of its robust structure and intelligent logic, it meets the strict security demands of regulated sectors. In addition, optional upgrades—such as biometric authentication, tamper detection, and anti-vandal coatings—enhance system performance and safety.

Installation and Use
Installation Steps
Installation begins with preparing a flat, reinforced surface where the system’s weight and movement can be properly supported. Electrical and communication lines should be pre-routed according to the wiring layout. Each unit is anchored using expansion bolts, and all power, sensor, and control wiring must be completed before commissioning.
Once installed, the system undergoes logic testing to ensure the interlock works correctly—only allowing one door to open at a time. Access control devices are connected and configured via RS485, TCP/IP, or Wiegand protocols. Emergency logic, alarm integration, and system responses are also tested at this stage.
Use
In use, the door operates in a guided sequence. Users authenticate at the outer panel; once verified, Door A opens. After the user enters and Door A closes, Door B unlocks. Sensors monitor occupancy, and unauthorized entry attempts trigger alarms.
Routine maintenance includes cleaning sensors, inspecting locks, checking control logic, and verifying emergency responses. All adjustments should be performed by certified technicians.

FAQ
FAQ
1. What is the main purpose of an AB interlocking door?
It creates a controlled buffer zone that allows only one person to pass at a time, preventing unauthorized tailgating or forced entry.
2. How does the interlock work?
Only one door can be open at a time. After the user passes through Door A and it fully closes, Door B will then unlock.
3. What if someone tries to enter with another person?
Sensors inside the chamber detect multiple occupants (by weight, volume, or thermal detection) and trigger an alarm or deny access.
4. Can it be used with biometric systems?
Yes, it supports integration with facial recognition, fingerprint scanners, palm vein readers, or any third-party system via standard protocols.
5. What happens during emergencies?
The system can be set to fail-safe (open both doors) or fail-secure (remain locked) depending on your fire and evacuation policy.
