Fits in standard wallbox and replaces 1-pole wall switch, ground connection required, gangable with other unitsLow profile design eliminates obtrusive "scanning device" lookConvenient pushbutton provides manual ON/OFF light switching at any timeTwo dual element PIR sensors used to widen detection range, relay switches at the zero crossing point of the AC power curve to ensure maximum contact life and compatibility with electronic ballastsSegmented fresnel lens provides optimum sensitivity and performance designed with an extensive "minor motion" area where even slight body movements will be detectedVandal resistant PIR lens, 1-unit can be used for 120 to 277 VAC lighting, compatible with both electronic and magnetic ballastsHorizontal field-of-view may be adjusted between 180 and 60 deg of arc by using integral blinders located on either side of the lens, no masking tape requiredManual ON/auto OFF mode for installations where manual ON switching is required but auto OFF switching is still desired for CEC title T24 energy savingsTo comply with T24, red LED indicator light flashes when sensor detects motion to verify detection is activeTime delay in adapting mode, the time delay can be configured from 30 sec (test mode), 5, 10 and 20 min, in non-adapting mode, the delay can be configured from 5, 10, 20 and 30 minLight sensor adjustable ambient light override ranges from approximately 20 to 5000+ LUX to prevent lights from turning ON automatically during periods of ample natural light, increasing energy savingsLight sensor enables the load hold OFF feature once level has been set, no neutral design is optional for retrofit applicationsSelf-adjusting delayed OFF time interval compensates for real time occupancy patterns, preventing unnecessary ON/OFF switchingExclusive Walk-through feature provides increased energy savings by not leaving the lights ON for an extended period after only momentary occupancyVacancy confirmation when the time out expires and the relays turns OFF, a 30 sec vacancy confirmation exists to turn the relays back ONFalse detection circuitryPresentation mode feature for slide or film presentations allows pushbuttons to turn lights OFF and keep them OFF while the room is occupiedAdditional manual service switch provided for installer to force lights to hold OFF or hold-ON during installationBeep warn - unit beeps 3 times after delayed OFF time expires, then waits 10 sec before turning lights OFFExclusive Leviton® high inrush stability (HIS) circuitry, specifically designed to handle today's high inrush electronic ballast loads and offer unmatched durability and service
