LMS-502SC | Recessed Can HFD Occupancy Sensor, 800W, 120/277V, 50/60Hz

IR-Tec LMS-509SC is a recessed can HFD occupancy sensor for ceilings and walls. The LMS-509 series member of the TRANS family is a line voltage switching occupancy sensor designed for all-purposes energy efficient lighting control. This motion sensor employs an advanced High Frequency Doppler (HFD) sensing technology to provide superior sensing performance of minor motions, such as typing, writing, or reading. The HFD technology is operating with high frequency (4~12GHz) radio waves which is capable of detecting the occupant's presence and movements without requiring unobstructed line-of-sight like PIR sensors.The Accu-Set digital potentiometer makes the sensor setting easier, faster and more accurate than the conventional analog potentiometer. 4 levels of sensitivity can be selected to provide optimum range via DIP switch setting. An exclusive Hybrid Switching technology makes LMS-509 series ideal to control the lighting with exceptionally high inrush current (HIC) while switching on, such as multiple LED or CFL lightings connected in parallel. The sensor comes with ambient light sensor (ALS) to inhibit switching on the light if the ambient light level is higher than the threshold set. This provides a second-to-none design and installation flexibility.  Brand:  IR-TEC Type:  Occupancy Technology:  HFD Lens:  360° Mount:  Recessed Color:  Off White Coverage:  20' Range:  2000 sq ft Wattage:  800W max Voltage:  120-277 VAC Hertz:  50/60Hz Control:  Dip Switch Certifications:  UL Length:  3.54" Width:  3.54" Height:  1.65" LMS-509 data sheetLMS-509 installation sheetLMS-500 mounting instructions  General Lighting   Classrooms Offices Bathrooms 8-20' Mounting Residential/Commercial Indoor/Outdoor Damp Rated    Occupancy-Vacancy sensor Rotary DIP settings switch Operation LED indicator Wire Leads included 360° Lens High Frequency Doppler Hybrid switching Accu-Set potentiometer 4 levels sensitivity setting Manual Control 120-277VAC multi-volt   30 day Seller Warranty 3 year Limited MFG Warranty
