Site Preparation and Multi-Lane Layout Architecture
The ZKTeco FBL 720 is an intermediate dual-lane builder unit engineered to construct multi-lane entrance control barriers within the FBL700 product family. When configuring an entrance layout, each FBL 720 serves as a shared central partition separating two adjacent 600 mm pedestrian lanes. Civil planning must accommodate the physical footprint of the unit, which measures 1200 mm in length, 300 mm in width, and 980 mm in height.
The installation floor must consist of a level, stable concrete surface capable of firmly anchoring the SUS304 stainless steel cabinet. Conduits for power, access control signals, and peripheral cabling must be routed from sub-floor ducts through the bottom entry points of the cabinet before bolting the chassis to the ground. For outdoor facilities, the turnstile requires a sheltered canopy overhead to operate reliably within its designated ambient temperature range of -28°C to 60°C and relative humidity range of 5% to 80% non-condensing.
Mains Power Hookup and Chassis Grounding
The FBL 720 is compatible with dual-voltage input ranges, operating on AC 100V–120V or AC 200V–240V at 50/60Hz. Prior to applying power, verify that the site voltage matches the power supply specification on the internal terminal blocks.
- Protective Earth Connection: A dedicated, reliable protective grounding line must be directly terminated onto the system protection ground terminal of the turnstile chassis. Proper grounding is mandatory to prevent personal injury, mitigate electrical interference, and protect internal motor drive components.
- Cable Segregation: High-voltage AC mains lines must be kept physically separated from low-voltage signal cabling to eliminate electromagnetic induction that could trigger sensor errors.
Access Control and Peripheral Signal Wiring
The internal control board interfaces with third-party and native access control hardware via dry contact relay inputs and Wiegand connections. Field technicians can integrate the FBL 720 with RFID readers (ID and IC), biometric fingerprint readers, visible light facial recognition terminals, and QR code scanners.
| Terminal Interface | Peripheral Type | Functional Description |
|---|---|---|
| Relay Input (NO/COM) | Biometric / Facial / QR Terminals | Transmits momentary dry contact pulse to trigger the 0.8-second barrier retraction cycle. |
| Wiegand Port | RFID Readers (ID / IC) | Routes card credential data directly to access management controllers. |
| Indicator Output | Integrated LED Displays | Drives status and directional LED signals to visually guide authorized pedestrian flow. |
Commissioning, Sensor Alignment, and Emergency Mode Validation
Once mechanical installation and electrical terminations are complete, remove the SPCC lid (finished with black baking paint) to access internal mechanical adjustments and sensor electronics. Align all opposing optical infrared detection sensors across each 600 mm passage lane. Ensure that the sensor lenses are clean and free of dust or obstructions, as blocked optical paths will trigger unauthorized entry alarms or prevent the retracting acrylic flaps from closing.
Perform operational testing to verify that pedestrian throughput can achieve up to 30 people per minute with opening acoustic noise remaining at or below ≤30 dB. Validate the built-in anti-collision mechanism by applying an external resistance against the acrylic wing; the mechanism must yield to protect internal drive components and smoothly auto-reset once the load is removed. Finally, cut mains power to confirm that the emergency mode functions correctly, ensuring the acrylic flaps automatically retract completely into the SUS304 cabinet to provide an unobstructed evacuation corridor.
