The Leviton® Provolt™ dual relay vacancy sensors 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. Vacancy timers continually analyze and adjust to changing conditions using the latest microprocessor based technology to optimize performance.

Commercial Applications
Time delay and sensitivity are continually adjusted to occupancy pattern of use
Industry exclusive self-configuring local manual switch input, momentary or maintained switches are supported
Test mode for simplified commissioning
In the event of product failure, return to closed feature causes the relay to default ON which eliminates life safety concerns
Industry exclusive HIS (high inrush stability) technology designed to handle today's high inrush electronic ballast loads and offer unmatched durability and service
The PIR scans for movement and shuts lights OFF after 31 min preventing false triggers from HVAC systems
30 sec to 30 min adjustable time delay
Auto-adapting
Industry-exclusive "fail-safe" circuitry - in the event of product failure, return-to-closed feature causes the relay to default on which eliminates life safety concerns
Industry-exclusive HIS (high inrush stability) technology designed to handle today's high inrush electronic ballast loads and offer unmatched durability and service
Robust and reliable mechanically held 10 A latching relay provides dependability and robust performance for all load types and provides energy savings over electronically held relays
Lenses on PIR models are easily replaceable and color-coded red (mid range) for contractors and end-users to easily identify lenses from the ground
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
Red - blinks when infrared is detecting motion and solid during device malfunction, yellow - blinks during test mode, solid with emergency/BMS input, blue - blinks when knob settings are changed, and green - blinks when U/S is detected
-26 to 71 deg C storage temperature
0 to 90% non-condensing relative humidity
