The ZKTeco SBTL320 is engineered specifically as an intermediate additional-lane swing barrier turnstile. Designed to integrate seamlessly with primary master turnstile pedestals such as the SBTL300 series, the SBTL320 enables facility managers and system integrators to scale single-lane access points into synchronized multi-lane pedestrian entrance corridors with a standard 750 mm lane width per passage.
Multi-Lane Barrier Architecture & Layout Integration
When planning multi-lane security checkpoints, the SBTL320 acts as the dual-sided intermediate cabinet placed between standard master barrier units. Each SBTL320 features a compact cabinet footprint measuring 1200 mm in length, 200 mm in width, and 980 mm in height, allowing multiple turnstile lanes to be installed side-by-side without consuming excessive lobby or corridor real estate. Its symmetrical SUS304 stainless steel casework and acrylic barrier wings align precisely with primary units to maintain uniform 750 mm lane widths across all access points.
- Primary Unit Pairing: Interoperates with master swing barrier turnstiles (such as SBTL300) to form continuous 2-lane, 3-lane, or larger access arrays.
- Passage Geometry: Supports dedicated 750 mm lane widths designed for smooth bidirectional pedestrian movement.
- Throughput Capacity: Rated for a maximum throughput speed of up to 30 people per minute per lane, with an acrylic barrier opening time of 0.8 seconds and quiet operation (≤30 dB opening noise).
Access Control & Verification Reader Compatibility
The SBTL320 features an open, simplified internal connection architecture that supports factory integration and field deployment with standard access control hardware. It accommodates user authentication protocols via integrated upper lid cutouts and reader mounts fabricated from SUS304 stainless steel and acrylic.
- Biometric Fingerprint Scanners: Compatible with integrated fingerprint recognition terminals for rapid biometric access verification.
- RFID Proximity & Smart Card Readers: Factory-ready for integration with RFID card readers to enable fast badge-in authentication.
- Status Indication & Diagnostics: Equipped with integrated LED directional indicators to guide pedestrian flow and an onboard LCD display screen that shows real-time running status and diagnostic operational feedback.
Sensor Integration & Anti-Tailgating Hardware
Pedestrian tracking, passage validation, and anti-tailgating logic on the SBTL320 are managed through 4 pairs of integrated infrared (IR) sensors positioned along the passage corridor. These onboard infrared arrays communicate directly with the internal controller to verify single-person throughput, detect unauthorized tailgating attempts, and prevent premature barrier closure while users are in transit.
Power, Safety, and Emergency System Interfacing
The SBTL320 operates across standard industrial power infrastructures and incorporates dedicated emergency interfaces to ensure full life-safety compliance:
- Electrical Input: Compatible with standard AC 110V/220V power sources operating at 50/60 Hz.
- Emergency Signal Triggers: Connects to centralized emergency and fire alarm control systems to force barrier wings open during facility alarms.
- Power Outage Fail-Safe: In the event of total electrical power disruption, the acrylic barriers unlock automatically, enabling users to easily push through the turnstile for unobstructed emergency egress.
- Environmental Compatibility: Suitable for indoor deployments or sheltered outdoor access points within an operating temperature range of -20°C to 70°C and a non-condensing relative humidity tolerance of 5% to 95%.
