Occupancy Sensor with Integrated Photocell, Line Voltage, Dual Relay, Ultrasonic, Ceiling Mount, 1000SF, 120-277V, Extended Range Lens installed, Provoltª

• Utilizes sensors which emit non-audible sound waves and sense movement. Any movement within the sensorÕs field-of-view causes a shift in the original emitted frequency. The sensor identifies the change as movement and controls light accordingly. U/S models are immune to external ultrasonic signals from other sources such as white-boards delivering uninterrupted performance.
• Auto-Adapting: Time delay and sensitivity are continually adjusted to occupancy pattern of use
• Vacancy Sensing Time Outs: (Delayed OFF Timer, Exclusive Walk-through Feature, Time delay and saved settings are protected during power outages and will return to the last known state)
• Output short circuit protection
• Industry-exclusive self-configuring local manual switch input: Momentary or maintained switches are supported
• Presentation Mode allows user to turn lights OFF and keep them OFF while the room is occupied
• Adjustable Time Delay: 30s, 5min, 10min, 20min, 30min
• Test Mode for simplified commissioning
• Manual Switch and Emergency Override are Class 1 or Class 2 circuits. Class 2 circuits provided for flexibility
• Industry-exclusive Òfail-safeÓ circuitry: In the event of product failure, Return-to-Closed feature causes the relay to default ON which eliminates life safety concerns
• Industry-exclusive H.I.S. (High Inrush Stability) technology designed to handle todayÕs high inrush electronic ballast loads and offer unmatched durability and service
• Robust and reliable mechanically held 10A latching relay provides dependability and robust performance for all load types and provides energy savings over electronically held relays
• Field of View: Units from 500 to 2000 square feet available
• Visual LED indicators for all states: (Green - Blinks during U/S detection and is solid during auto-calibration, Yellow - Blinks during test mode; solid with emergency/BMS input, Blue - Blinks when knob settings are changed and during photocell override
