The Sivananda TS-1 MD (SL) motorized drop-arm tripod turnstile is engineered to interface directly with industrial access control systems, life safety circuits, and building management frameworks. Its internal logic controller supervises the solenoid locking assembly and motorized drive mechanism, enabling low-latency coordination with both analog relay modules and digital security controllers.
Access Control Panel and Reader Interface Compatibility
Integration with access control infrastructure is managed via two discrete potential-free contact (PFC) inputs, designated respectively for entry and exit authorization. This universal contact-closure architecture ensures seamless compatibility with standard third-party hardware platforms, including:
- Centralized electronic access control panels (ACPs) equipped with dry contact relay outputs.
- Proximity and high-frequency RFID smart card readers.
- Biometric authentication terminals (fingerprint, facial recognition, or iris scanning).
- Barcode and QR code validation scanning units.
- Manual push-button desk consoles for security guard override.
Upon receiving a momentary contact closure signal across the appropriate PFC terminal, the internal logic validates the input, illuminates the appropriate directional lane status indicator, and disengages the solenoid positive action lock for a single authorized rotation through the 3 x 120º indexing cycle. Mechanical anti-reverse locking engages automatically once the arm has traversed 25º past the rest position, preventing unauthorized return or tailgating.
Emergency System and Fire Alarm Integration
The TS-1 MD (SL) includes dedicated integration capability for emergency life safety systems. The turnstile control board accepts emergency drop-arm command outputs from building Fire Alarm Control Panels (FACP). When the fire alarm contact is triggered, the turnstile automatically releases its horizontal drop arm to clear an unobstructed, hands-free egress corridor. Once the emergency condition clears and the input resets, the motorized mechanism initiates an auto-reset cycle to restore regular controlled access.
Electrical Power and Operating Compatibility

Lane Signaling and Architectural Layout Sizing
Visual throughput coordination is handled by integrated Green Arrow and Red Cross optical lane indicators mounted on the casework, eliminating the need for standalone external signaling lamps. For physical passage clearance and architectural integration, the turnstile cabinet measures 420 mm (L) x 1020 mm (H). It supports standard 380 mm stainless steel arms for a 630 mm passage width (TS-1 standard), or an optional 500 mm arm configuration providing a 750 mm walkway width (TS-2 standard) to accommodate varied facility walkway layouts. Floor anchoring is executed directly onto solid concrete substrate using standard anchor bolts.
