Security Standards: High turnstiles of BA3 and BL series. The standard of full access control

In modern physical security system design, there are areas where reliability is a key parameter. Where precise management of personnel flow and adherence to entry procedures are a priority – for example, in industrial plants, logistics centers, or modern office buildings – high turnstiles become the foundation of the security system.

Let’s look at the technical solutions of the BA3 and BL series from Gastop, which define contemporary standards in this category.

1. Traffic Engineering: Drive Selection and Operating Specifics

Advanced access control begins with matching the mechanism to traffic intensity and expected user comfort. These series offer two key drive variants:

• ZABR3 (Motor-assisted): The most advanced model used in BA3 and BL turnstiles. Equipped with a motor that, upon detecting slight pressure on the arm, takes over the rotation process, smoothly bringing the rotor to its resting position. This solution minimizes user physical effort and significantly enhances passage fluidity.

• MA3: A fully mechanical variant, ideal for locations where construction simplicity, high resistance to intensive use, and no need for mains power supply are priorities.

At the heart of the electronic versions is an encoder (electronic measuring system). It allows for millimeter precision in rotor positioning. Thanks to it, the control system immediately reacts to any irregularity, such as an attempt by an unauthorized person to pass right behind an authorized one (so-called tailgating), activating an effective reverse movement blockade.

2. Material Durability and Resistance to Exploitation

High turnstiles are an investment designed for years of intensive operation, often in demanding environmental conditions.

• Premium Materials: Standard construction from INOX AISI 304 stainless steel guarantees high resistance to corrosion and mechanical damage. Hot-dip galvanized or powder-coated variants are also available, allowing the finish to be matched to the facility’s aesthetics.

• Year-round operation: The devices are adapted for continuous operation across a wide temperature range – from -25°C to +50°C. Special seals and the selection of electronic components ensure stable operation regardless of weather conditions.

• Dimensions and barrier certainty: The high construction (in the BA3 model reaching 250 cm) and solid rotor infill create a physical barrier that prevents unauthorized circumvention of the device from above or below.

3. Smart Functions and System Integration

Modern infrastructure requires solutions that seamlessly integrate with the building management ecosystem.

• Intuitive configuration: The new generation electronics feature a built-in display with a program MENU. This allows for quick changes to operating parameters (e.g., unlock time or queuing logic) directly on the device, without the need for an external computer.

• Access Control and Time & Attendance Compatibility: The turnstiles are fully prepared for cooperation with proximity readers, biometrics, and time & attendance systems.

• Emergency Safety: Integration with fire alarm systems ensures automatic unlocking (fail-safe mode) in emergency situations, which is crucial for maintaining clear evacuation routes.

4. Practical Applications in Demanding Sectors

BA3 and BL models have proven their effectiveness in numerous, diverse implementations:

• Transport sector: Four-section BA3-1-4 models ensure strict separation of passenger flows at airports.

• Mass event facilities: At large sports arenas, versions compliant with EN-13200 (BA3-2-S) smoothly manage the movement of thousands of users during large-scale events.

• Mobility on construction sites: Thanks to special PK-BL-1 platforms, control systems can be easily relocated as work progresses on the investment site.
