System Compatibility and Third-Party Hardware Integration

The Sivananda RB Series single-lane retractable flap barrier is engineered for turnkey integration into comprehensive physical security and building automation environments. Utilizing an internal controller equipped with dedicated opto-isolated inputs and outputs, the barrier interfaces seamlessly with external third-party access control panels, master controllers, and validation terminals while maintaining electrical isolation to shield internal drive electronics against signal interference and voltage transients.

Credential Reader and Peripheral Interfacing

The opto-isolated I/O architecture enables native connectivity with a wide spectrum of authentication devices and credential readers commonly deployed in commercial and enterprise infrastructure. The system is compatible with the following interface hardware:

• RFID Proximity Readers: Direct input integration for proximity card and credential readers, allowing rapid contactless authorization for registered personnel.
• Biometric Validation Scanners: Compatible with both optical fingerprint scanners and facial recognition biometric readers for high-assurance access points.
• Barcode and QR Code Scanners: Signal integration with optical barcode and QR scanners, ideal for visitor entry management and temporary transit ticketing.
• Manual Override and Push Buttons: Dry-contact switching compatibility for security desk push buttons, reception release switches, and manual supervisor bypass stations.

Fire Alarm and Life Safety Integration

Life safety and emergency egress compliance are addressed through a dedicated opto-isolated fire alarm system interface. When connected to the building's central fire alarm control panel (FACP) or emergency broadcast relay, the barrier controller monitors external emergency triggers. Upon receiving an active fire alarm output signal, the system commands the Brushless DC (BLDC) drive mechanism to immediately retract the acrylic panels into the end column housings, establishing an unimpeded pedestrian egress corridor until the emergency condition is cleared.

Operational Modes and Throughput Profiles

The RB Series architecture accommodates diverse traffic operational requirements with configurable bi-directional transit logic. The single-lane configuration supports:

• Normally Closed (NC) Operation: The standard operating mode where acrylic barrier panels remain extended and mechanically/electronically locked until a valid credential signal is registered.
• Normally Open (NO) Operation: An optional configurable operational state where barrier panels remain retracted, closing rapidly only when an unauthorized or fraudulent transit attempt is registered.
• Passage Clearance Compatibility: Adaptable mechanical configurations for standard 520 mm walkway passage widths (0.5-second opening/closing cycle) or 900 mm wide-lane passage clearances (1.0-second opening/closing cycle), designed for up to 20 persons per minute pedestrian throughput.

Electrical and Infrastructure Specifications

Deploying the single-lane RB Series barrier into existing or new facility power networks requires standard commercial mains power. The unit connects directly to a 230 V AC, 50 Hz single-phase electrical supply line drawing a nominal operating current of 1 Amp. Internal conduits integrated between the two end column casework pedestals streamline control signaling and power distribution between housings, ensuring full functional synchronization of the bi-directional retractable acrylic flaps.
