MST
Perimeter Full Height Turnstiles
Alvarado’s MST series sets the standard for secure fence line access. Built for outdoor environments, MST turnstiles are trusted across critical infrastructure, industrial sites, and high-security perimeters. With fully welded steel construction and reliable one-to-one passage control, MST models offer unmatched durability, tamper resistance, and integration flexibility. Available in standard, motorized, touchless, wide-lane, and tandem configurations.
Designed to last
Superior construction
Alvarado full height turnstiles are engineered from the ground up to secure outdoor perimeter lines with uncompromising reliability and structural integrity. All MST-series models are fully welded at the factory — not bolted together onsite like many alternatives — ensuring maximum strength, precise fit, and a clean, tamper-resistant finish.
These turnstiles are ideal for high-security environments requiring consistent one-to-one entry control and seamless integration with access control systems. Options include manual or electric lock control, touchless or motorized operation, wide passageways, tandem units, and enhanced tailgating deterrence.
Core Features:
- Fully welded steel construction with no exposed bolts or fasteners
- Precision mechanical design with splined rotation assembly for minimal play
- High-quality sealed bearings and stainless-steel components for durability
- Rugged turnstile controller with surge protection and conformal-coated circuitry
- Single or bi-directional operation, manual or electric lock control
- Independent fail-safe/fail-secure settings per direction
- Automatic self-centering and speed-controlled rotation
- Weather-resistant build for consistent outdoor performance
- Built-in override controls for flexible use modes (free pass, locked, controlled)
- Attachment points for credential readers and integration hardware
- Available in a wide variety of finishes and configurations
End User Benefits:
- Maximizes perimeter security with true one-at-a-time access
- Minimizes tailgating and unauthorized entry attempts
- Built for long-term, continuous operation in high-traffic outdoor settings
- Quick, intuitive passage with smooth and controlled rotation
- Adapts to a wide range of security policies and facility needs
- Compatible with all major access control systems
- Low maintenance and simple to install
- Attractive appearance, regardless of finish or configuration
- Touch-free and motorized options improve hygiene and reduce cleaning needs

Safety features you shouldn’t be without
Engineered for User Protection and Compliance
MST full height turnstiles are designed to ensure safe, controlled operation across all models — whether mechanical or motorized. Each unit includes integrated features that enhance user safety, reduce mechanical risk, and comply with global safety and performance standards.
Mechanical Models (MST, MSTT, MST 47, FMST)
These models feature a built-in speed control mechanism that automatically adjusts to the user’s pushing force. Even during aggressive use, rotation remains steady and controlled, minimizing the risk of injury from fast-spinning arms or rebound. The rotating section returns smoothly to its home position after each use and locks in place for the next user. An anti-entrapment cam mechanism makes it mechanically impossible to be locked inside the turnstile.
Motorized Models (MST-TE, MST-M)
Motorized MST models provide smooth, powered rotation — with or without user contact. In the touchless MST-TE, an overhead sensor initiates rotation after credential verification. The intelligent drive system monitors for unexpected resistance and stops rotation if it detects an obstruction, further enhancing user protection.
Emergency Readiness and Fail Modes
All MST models support configurable fail-lock and fail-safe operation. The most common configuration prevents entry (fail-lock) while allowing exit (fail-safe) during a power loss. Local override controls and dedicated fire system inputs enable fast egress during emergencies. Field adjustment between fail modes is straightforward and requires no special tools.
