The Sivananda single-lane retractable flap barrier (KT SKU: KTI02008004FTSS) is engineered for broad interoperability with industrial security systems, building management systems (BMS), and physical access control systems (PACS). Its open integration architecture utilizes dedicated opto-isolated inputs and outputs, ensuring clean electrical isolation between the barrier's internal 24 V DC logic controller and external control panels.
Access Control Signal Modes and Input Architecture
The control board supports both pulse-mode and potential-mode control signaling. This dual-mode capability allows systems integrators to interface the barrier with virtually any commercial access control panel or relay board without requiring intermediate signal-conditioning modules. The opto-isolated inputs isolate field circuitry against electrical transients and ground loops, maintaining signal integrity across industrial and commercial environments.
Credential Reader and Peripheral Integration
The stainless steel housing accommodates flush or bracket integration for a comprehensive range of identification and authentication hardware:
- RFID Card Readers: Compatible with standard proximity and smart card readers operating dry-contact or transistor-transistor logic (TTL) switching outputs.
- Biometric Terminals: Interfaces with fingerprint readers and optical biometric validation hardware.
- Facial Recognition Devices: Accepts relay and digital trigger outputs from stand-mounted or cabinet-mounted face recognition terminals.
- Barcode and QR Code Scanners: Compatible with 1D/2D optical barcode and mobile QR code scanners utilized in visitor management and ticketing infrastructure.
- Manual Override Inputs: Supports hardwired manual push-button consoles for security desk guard operation and reception override.
Emergency Systems and Fire Alarm Interfacing
Life safety system compliance is facilitated through a dedicated emergency input trigger. When interfaced with a fire alarm control panel (FACP) or emergency breakout switch, an incoming alarm command automatically triggers the internal 24 V DC brushless motor drive to retract the transparent acrylic flaps inside the casework. This instantly unblocks the 520 mm passage walkway, providing an unobstructed egress route for facility evacuation.
Electrical and Cabling Infrastructure
The single-lane barrier assembly consists of two barrier housing units requiring synchronized inter-cabinet communications. Physical interconnectivity between the housings is handled via dedicated interconnecting cables (one 3-core cable and one 14-core cable). Both cable runs are routed through a 100 mm x 100 mm floor trench provided between housings in the concrete floor as specified by the manufacturer installation layout. The system connects directly to a standard 230 V AC utility power supply, drawing 75 W under nominal operation and up to 100 W during peak motor drive acceleration.
