Leviton today announced the introduction of its Provolt ODC family of line-voltage occupancy and vacancy sensors.
The new sensors simplify energy management with an easy to install self-contained solution. Provolt occupancy sensor models include line voltage occupancy sensing, daylight harvesting and manual-ON/auto-OFF override control in a single unit with no special control stations required.
The integrated design eliminates separate power pack and sensor wiring for additional savings in labor, time and material. Available in passive infrared, ultrasonic and multi-technology versions, the new line features both single and dual relay versions with mid-range, high-density and extended range lenses included with select models.
"We engineered the Provolt ODC family of line-voltage sensors to provide robust performance and reliability, optimal energy-savings and compliance with the most rigorous testing standards," said Richard Westfall, vice president and general manager, Leviton Lighting & Energy Solutions. "Many industry-leading Leviton exclusive features are built-in to ensure reliability, safety and ease of installation. The innovative integrated design is installer-friendly, reducing labor and commissioning time. The occupancy sensor line's built-in photocell enables true daylight harvesting capabilities to secure even greater energy savings."
Provolt occupancy sensor models switch connected loads ON when occupancy is detected and automatically switch them OFF after a predetermined time interval after the space is vacated. Vacancy sensor versions require connected loads to be switched ON manually and automatically turn them OFF when occupancy is no longer detected.
All models feature Leviton's auto-adapting technology which continually adjusts to occupancy patterns to deliver optimal performance reliability and false triggering prevention. To further enhance energy savings, Provolt occupancy sensor models feature true daylight harvesting (both open and closed loop) through an integrated photocell that automatically activates or deactivates connected loads (e.g., lighting, fans, HVAC, etc.) in conjunction with the presence or absence of natural light. In instances of power failure, an automatic time-delay with auto-save feature returns the time-out setting to the last saved level once power is restored.
The Provolt ODC's contractor-friendly, compact, one-piece design significantly reduces installation time over low-voltage sensors that require a separate power pack to supply voltage to the unit. An industry-exclusive self-detecting, configurable manual switch input (for both momentary and maintained contacts), terminal blocks and screw guides on the sensors significantly speed installation and setup.
The new sensors feature robust performance for all load types and a mechanically-held 10 Amp latching relay that delivers power savings beyond electrically-held relay designs. All Provolt ODC sensor models feature Leviton's industry-leading fail-safe circuitry. The circuitry returns the sensors' electronics to a "closed" position to maximize safety once power is restored after an electrical outage. Another Leviton exclusive – high inrush stability (HIS) circuitry – accommodates a variety of high inrush electronic ballast loads. Factory calibrated zero-crossing circuitry on the sensors extend their relay life.
Provolt sensors are ideal for installation in tight ceiling spaces with limited access for low-voltage wiring, new construction projects aimed at energy conservation and retrofit environments requiring compliance with the latest energy mandates. The Provolt ODC line of sensors is listed to UL 773A and UL 924. They are CE Compliant, cUL Listed, RoHS Compliant, NOM Certified, CA Title 20/24 Compliant and backed by Leviton's Limited 5-Year Warranty.
