BLASI – Transmitter

The BLASI – Transmitter generates modulated infrared signals matching ELS300 receiver specifications, establishing invisible safety curtains within revolving door drums that instantly halt FlipFlow wing rotation upon beam interruption by pedestrians or obstacles during high-traffic operation across two-wing security, three-wing standard, and four-wing high-capacity configurations. Operating on 10-30VDC auxiliary supplies common in BLASI controls, the transmitter delivers stable 850nm wavelength output with automatic power adjustment compensating for dust accumulation and lens contamination while consuming minimal <10mA current.

The Ø12mm housing snaps into factory 12.5mm drum mounting holes alongside matching receivers, using identical M8 4-pin connectors for plug-and-play integration and Y-splitter networking enabling multi-beam configurations in wide drum applications. Status LEDs confirm power supply health and transmission integrity visible through drum wall cutouts while ±5° beam divergence maintains reliable coverage despite minor misalignment from mechanical wear over years of service.

100,000 lux ambient light immunity prevents sunlight interference while rugged IP65 construction withstands cleaning chemicals, vibration from adjacent drives, and -20°C to +60°C temperature extremes typical in Dubai commercial installations. Field technicians appreciate exact receiver compatibility across NPN/PNP configurations, polarity protection preventing field wiring errors, integrated optics eliminating external lenses, and universal mounting matching all FlipFlow safety beam layouts ensuring regulatory compliance worldwide.
