Uses industry exclusive digital (4 element) PIR circuitry for fewer false triggers from unwanted sources such as HVAC systemsA fresnel lens establishes dozens of detection zones requiring the heat source to move from one zone to another to trigger the sensorAuto-adapting time delay and sensitivity are continually adjusted to occupancy pattern of useIndustry exclusive self-configuring local manual switch input, momentary or maintained switches are supportedIndustry exclusive "fail safe" circuitry in the event of product failure, return to closed feature causes the relay to default ON which eliminates life safety concernsPresentation mode allows user to turn lights OFF and keep them OFF while the room is occupiedTest mode for simplified commissioningManual switch and emergency override are class 1 and 2 circuits, class 2 circuits provided for flexibilityRobust and reliable mechanically held 10 A latching relay provides dependability and robust performance for all load types and provides energy savings over electronically held relaysLenses are easily replaceable and color coded blue (high density) and red (mid range) for contractors and end users to easily identify lenses from the groundRed visual LED indicator blinks when infrared is detecting motion and during photocell manual calibration, solid during device malfunctionYellow visual LED indicator blinks during test mode, solid with emergency/BMS inputBlue visual LED indicator blinking light indicates photocell overrideConfigurable for manual ON/automatic OFF or automatic ON/automatic OFFAdjustable time delay
