BLASI – Light curtain

The BLASI – Light curtain establishes multiple redundant infrared detection planes spanning critical entrapment zones within revolving door drums, immediately signaling FlipFlow controllers to halt wing rotation upon detecting pedestrians, cleaning equipment, or obstacles during normal operation across two-wing security, three-wing standard, and four-wing high-capacity configurations serving global hospitality, retail, and corporate facilities. Operating on 24VDC control power, the curtain transmits 100+ synchronized modulated beams with <15ms response time meeting stringent EN 16005 and international safety standards for pedestrian access equipment.

Integrated self-testing continuously validates transmitter alignment, receiver sensitivity, and response circuit integrity while multi-segment status displays confirm operational health through drum wall observation windows. IP65 sealed aluminum profiles mount flush to factory drum framing using standardized brackets while automatic ambient light compensation maintains detection reliability despite shopping center lighting variations and direct sunlight penetration common in glass entrance designs.

Field service personnel benefit from modular beam segment replacement, universal M12 connectors matching FlipFlow safety wiring, and built-in alignment aids eliminating beam-by-beam adjustment during installation or post-maintenance verification. Dual NPN/PNP output compatibility supports both legacy and modern BLASI controllers while integrated muting inputs enable selective deactivation during authorized maintenance windows. The light curtain’s patented beam coding prevents cross-talk interference in adjacent door configurations while response time validation circuits ensure regulatory compliance across diverse environmental conditions worldwide.
