The Madoors USA MDRS-300 Motorized Full Height Double Turnstile is a microprocessor-controlled, CE-certified, ISO 9001:2000-certified double full-height turnstile system manufactured from 304 quality stainless steel — providing the highest security pedestrian access control for narrow entrances requiring maximum passage width in minimum space, designed to prevent jumping over unlike standard turnstiles, and integrating with fingerprint, face recognition, iris-eye scanning, vein recognition, card reader, barcode, and QR code access control systems. The 2-year guaranteed system automatically switches to free passage mode on fire, earthquake, and disaster emergency alarms, uses a 24V DC brass rotator with electromagnetic lock system and upper shaft that does not bend or break under body loading, operates at 220VAC, and is available in three-arm high-security and four-arm high-security configurations in fully painted, fully stainless, or middle-rotor-stainless body-painted finish — widely used as stadium barcode turnstiles and prison iris scanning turnstiles.
TECHNICAL SPECIFICATIONS
The Madoors USA MDRS-300 Double Full Height Turnstile is manufactured from 304-grade chrome-nickel stainless steel — the 304 specification provides the chromium and nickel content required for corrosion resistance in outdoor weather conditions without surface treatment maintenance. Full dip galvanized steel is also available for the maximum corrosion protection in the most aggressive outdoor environments.
The full height double turnstile design provides coverage from floor to ceiling height — unlike waist-height turnstiles that can be jumped over or crawled under, the full-height construction physically prevents all unauthorized bypass attempts. The double configuration — two adjacent full-height turnstile lanes in a single unit — provides the highest passage density in the minimum floor space for narrow entrance positions where a single wide turnstile or multiple separate units cannot be accommodated.
The mechanical structure is the market-leading minimum-space maximum-passage-width design — the complete double turnstile mechanism fits within a smaller footprint than two separate full-height turnstile units while providing the same two-lane throughput. The electromagnetic lock system holds the rotor in the locked position between authorized passages and releases it under the control of the microprocessor when an authorized credential is presented. The upper shaft and lock system are engineered to withstand body loading during transition without breakage or bending — providing long-term structural integrity under the physical stress of high-cycle pedestrian access control.
The 24V DC brass rotator provides the drive force for motorized arm operation — brass construction provides corrosion resistance and dimensional stability for the precision-engineered rotator component. The 220VAC mains supply is converted to 24VDC for the rotator and electromagnetic lock through the integrated control board.
The microprocessor control provides all operating modes — two-way single pass, single pass in the set direction, always free or locked, free passage in the set direction — and integrates with all access control dry contact signals from card readers, fingerprint readers, face recognition devices, iris scanners, vein recognition systems, barcode readers, and QR code readers. The dry contact interface provides universal compatibility with any access control technology without requiring specialized interface hardware.
Emergency mode — automatic free passage on fire alarm, earthquake alert, and disaster emergency signals — is the standard legal compliance function, ensuring unrestricted emergency egress in all emergency evacuation scenarios.
KEY FEATURES
Full Height — Jumping-Over Prevention
The full height construction that physically prevents jumping over is the definitive security advantage of the MDRS-300 over waist-height turnstile alternatives — the floor-to-ceiling height barrier eliminates the primary bypass method available at waist-height turnstiles, directly providing the highest level of physical access control without relying on observation or enforcement by security staff. This anti-jump design makes the MDRS-300 the appropriate specification for the highest security pedestrian access requirements including prisons, high-security government facilities, and any location where unauthorized entry by jumping is a credible threat.
Double Lane — Maximum Passage Width in Minimum Space
The double full-height turnstile in a single unit providing maximum passage width in minimum floor space is the specific design advantage for narrow entrance positions — the MDRS-300 provides two simultaneous access lanes in the space that would normally accommodate only one separate full-height turnstile. This space efficiency directly enables full-height security at entrance widths that cannot accommodate two separate units, making high-security access control achievable at the most constrained building entrances.
All Biometric & Card Technologies — Universal Access Integration
The integration with fingerprint, face recognition, iris-eye scanning, vein recognition, card reader, barcode, and QR code technologies through standard dry contact signals provides universal compatibility with any access control technology present or future — the same turnstile hardware serves the most basic proximity card installation and the most advanced multi-biometric prison security system through the same dry contact interface. This universal integration directly eliminates the hardware replacement requirement when access control technology is upgraded.
Electromagnetic Lock — Secure Holding & Precise Release
The electromagnetic lock system provides positive holding force on the rotor in the locked position — the electromagnetic lock holds the rotor against manual force attempts that would bypass a purely mechanical lock, and releases precisely on the authorized credential signal from the microprocessor. This electromagnetic holding directly prevents the manual forcing of the locked turnstile that affects mechanical-only lock systems.
Brass 24V DC Rotator — Corrosion-Resistant Precision Drive
The 24V DC brass rotator provides the motorized drive force for arm rotation with the corrosion resistance of brass construction — the brass material maintains the precise dimensional tolerances of the rotator mechanism without the corrosion that would cause binding and increased operating force in steel rotators exposed to the humidity and moisture of outdoor and aquatic facility installations.
No Upper Shaft Breakage Under Body Loading
The specific engineering of the upper shaft and lock system to withstand body loading during transition without breakage or bending addresses the primary mechanical failure mode of full-height turnstiles in high-traffic applications — when pedestrians lean, push, or force against the arms during transition, the upper shaft experiences significant bending load. The MDRS-300 engineering directly eliminates this failure mode, maintaining structural integrity and maintaining access security function throughout the complete service life.
Stadium Barcode & Prison Iris Scanning Applications
The specific identification of stadium barcode reader and prison iris-eye scanning as the primary application examples confirms the MDRS-300's practical deployment track record at the two most demanding pedestrian access control environments — the high-throughput mass-event management of stadium entry where thousands of ticket holders must be processed rapidly, and the maximum-security individual identity verification of prison access where iris scanning provides the highest available biometric identity confirmation. These reference applications directly confirm the reliability and performance of the MDRS-300 across the complete security level range.
CE & ISO 9001:2000 Certified — International Quality Standards
The CE certification and ISO 9001:2000 quality management certification provide the internationally recognized compliance documentation required for government, prison, and public infrastructure procurement — CE confirms European safety standard compliance and ISO 9001:2000 confirms the quality management system governing the manufacturing process. These certifications directly support the procurement compliance documentation requirements of institutional buyers.
Emergency Free Passage — Fire, Earthquake & Disaster Compliance
The automatic free passage mode on fire alarm, earthquake alert, and disaster emergency signals ensures that the full-height turnstile does not obstruct emergency evacuation — the highest-security physical barrier automatically becomes a completely unobstructed free passage when emergency evacuation is required. This emergency compliance function is the legal requirement that enables full-height turnstile deployment at public and commercial facilities where emergency egress must not be compromised by access control hardware.
