The ENSA-PS3 is an intelligent sensor switch, designed for recessed mounting in ceilings. It features configurable ambient light sensing, passive infrared motion detection and on-time delay, so you may tailor light usage and energy consumption to your exact specifications. Add three step energy saving to any light with sensor switches: 1) Daylight sensor: Activates motion sensor when lux levels fall below limit 2) Motion sensor: Detects movement, turns light on only when necessary 3) On-timer: Light-on duration is set only as long as is required Product features: Automatically activate and deactivate lighting for energy efficiency Adjustable sensors: Daylight (3~2000lx) / Motion (6m) / On-timer (10s~15min) 360° circle / Ø6m passive infrared detection Recessed ceiling mount, for indoor use only 3 year warranty Specifications Features Daylight Sensor - Yes Motion Sensor Type - Passive Infrared Electrical Input Voltage - 220 ~ 240VAC 50Hz Power Consumption (Sensing Mode) - 0.5W Max.
