BLASI – light barrier 2181 FIGARI

The BLASI – light barrier 2181 FIGARI delivers proven anti-trap protection through multiple modulated infrared beams positioned at critical heights within revolving door drums, instantly halting wing movement upon pedestrian detection during rotation phases common in two-wing security, three-wing standard, and four-wing high-capacity configurations serving international hospitality, retail, and corporate facilities. The FIGARI system’s patented automatic range compensation continuously adjusts transmitter power and receiver sensitivity to maintain detection reliability despite dust accumulation, lens contamination, and ambient light interference from shopping mall lighting and external sunlight penetration.

Featuring NPN open-collector outputs integrating directly with FlipFlow 2 safety input circuits, the light barrier supports 10-30VDC operation from control auxiliary supplies while providing normally-open and normally-closed relay contacts for redundant safety monitoring. Rugged aluminum housings with IP65 sealing mount securely to drum frame profiles using factory-drilled patterns while multi-colored status LEDs confirm beam alignment, power supply health, and contamination status visible during routine maintenance inspections.

Field technicians value the integrated test function enabling complete safety circuit validation without physical obstruction, sequential beam identification eliminating troubleshooting confusion across multi-beam configurations, and universal mounting brackets accommodating both left-hand and right-hand door rotation directions. The 2181 FIGARI’s 50m maximum range supports oversized entrance installations while <5ms response time meets stringent international safety standards for entrapment prevention. This light barrier system ensures continuous pedestrian protection and regulatory compliance across diverse global commercial environments.
