  1. The NightLite Sensor

  2. Introducing the NightLite Sensor The Occupancy Sensor that is a Night Light!

  3. Perfect for Hotel Bathrooms • Many people leave light on all night • 24/7 lighted push-button provides enough light for 2 am trip to bathroom without having to turn on bright overhead lights! • If occupant wants to turn on overhead lights, the night light is the On/Off switch. • Passive Infrared (PIR) detection turns lights off if no occupancy

  4. NightLite Sensor (WSD-NL) Technical Features • Passive Infrared (PIR) occupancy detection provides coverage up to 10 feet for small hand motions and 20 feet for walking motions • Draws 1/10 of a Watt at 120VAC (7-10 times less than other night light devices • Can control lights and/or exhaust fans (1/4 HP Motor load) • Patented either/or wiring for hot and load wires makes installation simple (neutral & ground also required) • No minimum load requirements

  5. NightLite Sensor (WSD-NL) Programmable Features • Device contains microcontroller “brain” that is push-button programmable • Default operation is Auto On/Auto Off • Manual On is user selectable • Optional Reduced Turn-On Sensitivity Mode (eliminates PIR reflection off glass • Switch can also be disabled • Off time delay is factory set to 60 minutes, but is selectable up to from 15 minutes to 2 hours (in 15 min. increments)

  6. NightLite Sensor (WSD-NL) Physical Features • Mounts to standard switch box • Fits next to GFI receptacles • Vandal resistant lens • Conformally coated circuit board provides corrosion protection from condensation caused by high humidity (steam) in bathrooms • UL/CUL listed • 5 Year Warranty • Made in the USA

  7. How does a PIR Sensor Work? Answer: • Uses Passive Infrared (PIR) detection to “See” • Sensor detects “Heat in Motion” • You look like a moving 60 Watt light bulb!

  8. How does a PIR Sensor Work? • Two wafer thin Pyro-Electric elements are encapsulated and positioned behind a Fresnel lens Lens Detector • Each lens segment generates a pair of collector beams • The distance behind the lens is called the “Focal Length” • The Focal Length determines the size of the beams

  9. How does a PIR Sensor Work? • When People Move they Enter and Exit the Beams • The PIR Detector then “Sees” Changes in Energy < < < < < < < < < < < < • Body Heat in “Motion” Turns On the Sensor! AUTO

  10. How does a PIR Sensor Work? • When People Move they Enter and Exit the Beams • The PIR Detector then “Sees” Changes in Energy • Body Heat in “Motion” Turns On the Sensor!
