Answer:
The ZKTeco FBL220 is specifically designed as an intermediate dual-barrier pedestal to expand multi-lane configurations. Built with SUS304 stainless steel casework and acrylic wings, it incorporates an onboard control board LCD and emergency automatic wing retraction.
Unlike standalone perimeter barriers that only control a single passage flank, the ZKTeco FBL220 is purpose-built as an intermediate expansion unit for multi-lane turnstile arrays:
- Dual-Flap Intermediate Design: Houses dual motorized retracting acrylic wings within a single central pedestal, enabling facility managers to add lanes incrementally between boundary turnstiles without installing redundant cabinetry.
- SUS304 Stainless Steel Casework: Built with robust SUS304 grade stainless steel across the cabinet body and top lid, featuring a smooth exterior with no exposed screws for tamper resistance and pedestrian safety.
- Onboard Configuration Display: Equipped with an integrated LCD directly on the main control board to simplify commissioning, operational adjustments, and status diagnostics.
- Fail-Safe Emergency Operation: Acrylic barriers automatically retract upward during emergency alarm triggers and drop during mains power failures when an auxiliary backup battery (they are not included) is installed.
