Roll over for zoom Provolt™ vacancy sensor lighting control, line voltage, 8 - 12 ft ceiling mount, PIR Sensor 1500 sq-ft, daylighting, auto-calibration, 120 - 277 VAC/CA 50/60 Hz. UL/CE, RoHS and CEC Title 20/24 compliant. The Leviton Provolt™ series combine line voltage vacancy sensors into a self-contained unit. The integrated design alleviates the need for separate power pack and vacancy sensor wiring making it a low-cost, efficient energy solution for new construction and retrofits. Time delay and sensitivity are continually adjusted to occupancy pattern of use Configurable for manual on/auto off The sensor will turn lights OFF if no motion is detected after a specified time Exclusive walk-through feature: provides increased energy savings by not leaving the lights on for an extended period after only momentary occupancy The PIR scans for movement and shuts lights off after 31 min preventing false triggers from HVAC systems
