June 23, 2014: New Occupancy and Vacancy Sensors Simplify Energy Management
Sensors Offer Contractor-Friendly Integrated Design
MELVILLE, N.Y. — Leviton has announced the introduction of its Provolt ODC family of line-voltage occupancy and vacancy sensors. The company said 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 savings in labor, time, and material, said the company. 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.
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., HVAC, fans, lighting, 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 reduces installation time over low-voltage sensors that require a separate power pack to supply voltage to the unit. A self-detecting, configurable manual switch input (for both momentary and maintained contacts), terminal blocks, and screw guides on the sensors speed installation and setup.
