The ZKTeco FBL220 dual-barrier flap turnstile is engineered specifically as an intermediate expansion unit for high-traffic pedestrian entrance control arrays. Because it is equipped with dual retracting acrylic barrier wings—one on each side of the pedestal casework—it does not operate as an isolated standalone lane. Instead, deploying the FBL220 requires architectural coordination alongside primary single-sided master and slave units to establish two or more contiguous access lanes.
Multi-Lane Turnstile Array Integration
The FBL220 series is purpose-built to integrate directly with ZKTeco FBL200 series primary turnstile units. In a standard multi-lane layout, an FBL200 master unit and an FBL200 slave unit define the outer perimeter flanks, while one or more FBL220 intermediate pedestals bridge the space between them to form continuous, parallel pedestrian channels. This modular pairing ensures uniform aesthetic alignment, matching SUS304 stainless steel cabinet contours, and synchronized lane widths of 570 mm (datasheet standard) to 600 mm (ERP listing dimension) across every individual passage.
Access Control Reader & Credential Interfacing
To accommodate diverse facility security protocols, the FBL220 supports versatile access control electronics and comes ready for customer-specified reader integration:
- RFID & Smart Card Readers: Supports surface or internal integration for contactless RFID proximity technologies, enabling high-speed credential verification for employee and visitor management.
- Biometric Fingerprint Terminals: Compatible with integrated biometric fingerprint access control devices for heightened identification verification.
- Hybrid Verification Systems: Accommodates dual-authentication installations combining card readers and biometric identification hardware.
- Visual Directional Signaling: Integrates built-in directional LED indicator support to provide real-time green arrow or red cross passage status signals to approaching pedestrians.
Control Board & Commissioning Compatibility
The unit features an integrated flap barrier control board equipped with an onboard LCD screen. This configuration interface allows security engineers and technicians to commission passage operational modes, calibrate barrier open/close timings, and monitor diagnostics directly at the lane without relying on external configuration software. The mechanical assembly achieves an opening speed of 0.8 seconds and maintains low acoustic operating noise of ≤30 dB, making it acoustically suitable for quiet commercial lobbies, enterprise facilities, and administrative headquarters.
Power Infrastructure & Life-Safety System Integration
The FBL220 is compatible with global standard utility power lines, operating reliably across AC 100V to 120V and AC 200V to 240V at 50/60 Hz line frequency. For site life-safety compliance, the turnstile interfaces with facility emergency management and fire alarm systems. In an alarm condition, the acrylic barriers retract automatically into the SUS304 casework to provide immediate, unhindered egress. In the event of primary mains utility loss, automatic wing retraction is maintained if an optional emergency backup battery (they are not included) is connected to the internal power terminals.
Architectural & Environmental Operating Envelope
System integrators must verify site dimensions against the FBL220 pedestal footprint of 840 mm × 1150 mm and chassis dimensions of 1200 mm (L) × 300 mm (W) × 980 mm (H) [with ERP alternate reference dimensions of 1150 mm (L) × 300 mm (W) × 1000 mm (H)]. The SUS304 stainless steel enclosure is suitable for indoor access points or sheltered outdoor environments, rated to operate in ambient thermal conditions ranging from -28°C to 60°C and non-condensing relative humidity levels between 5% and 80%.
