The Bioteknix FHT‑TL‑239 is a double-door full-height turnstile engineered for high-security entry points. Constructed with premium SUS304 stainless steel, it supports both bi‑directional and uni‑directional rotation. A built‑in microcomputer controller is programmable for custom use, integrating via dry‑contact or high/low‑level signals. The power supply options include AC 220 V±10% and DC 24 V 3 A or 12 V 3 A. Operating reliably in –30 °C to +80 °C and 5–90% humidity, it features waterproof sealing for indoor or outdoor environments. Throughput is up to 25 people per minute, with a switching time of approximately 1 second. After battery-less power failure, it unlocks automatically to allow free exit and entry. Designed for longevity, the mechanism boasts a mean cycle-to-failure rating of 5 million cycles. There are four reader mounting points and maintenance access portals. Optional add-ons include RFID/IC readers, barcode scanners, infrared detectors, UPS support, and fire‑panic compliance integration.
