Introducing the NightLite Sensor The Occupancy Sensor that is a Night Light!
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! Perfect for Hotel Bathrooms 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
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
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) NightLite Sensor (WSD-NL) Programmable 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 NightLite Sensor (WSD-NL) Physical Features
Answer: Uses Passive Infrared (PIR) detection to See Sensor detects Heat in Motion You look like a moving 60 Watt light bulb! How does a PIR Sensor Work?
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 Detector Lens Two wafer thin Pyro-Electric elements are encapsulated and positioned behind a Fresnel lens
