Photocell, Switching, Dual Relay, ON/OFF, Provolt

• Leviton Provolt™ Line Voltage Photocell is a first of- its-kind, self-contained mini daylight harvesting system offering the functionality of a 1-10V dimming photocell combined with the robustness of a Leviton power pack. Ideal for daylight harvesting applications and lighting control in airports lobbies, commercial lobbies, conference rooms and classrooms. The integrated design eliminates the need for additional components such as a separate power pack and low voltage photocell making it a low-cost, efficient energy solution for new construction and retrofits. The Provolt Line Voltage Photocell uses patented daylighting design level technology to autocalibrate a room or corridor for a more accurate daylight harvesting operation. The photocell maintains the architectural lighting design level through calculation and measurement of ambient (natural and artificial) lighting and fine dimming adjustment. For installers, the Provolt Line Voltage Photocell provides a simple all-in-one solution for new construction and flexible retrofitting. This revolutionary photocell auto-detects existing momentary or maintained switches and will work automatically with either. The photocell also complies with growing energy regulations and includes a connection for emergency lighting and demand response to meet California Title 24 and ASHRAE Standard 90.1 2010.

• Self-contained, open and closed loop daylight harvesting system
• Includes two removable light pipes (flat or angled) for open and closed loop daylight harvesting applications
• Leviton-exclusive auto-calibration eliminates the need for on-site configuring at a specific time of day
• Industry exclusive “fail-safe” circuitry assures lights ON to meet life safety requirements (NFPA101)
• Auto-detects momentary or maintained wall station for manual override control
• Manual calibration — used for precise fine tuning and open loop applications
• Low voltage contact closure uses: - Wall station — dimming/switching and daylight harvesting control - Emergency lighting — energy savings and safety - Demand response — meets energy codes - BMS integration — incorporate into whole building controls
• Forced ON — user forces lights on for 2 hours through wall station, auto-exit to daylighting state
• Forced OFF — user forces light off through wall station
• Test Mode — fade rate is set to 30 seconds for 60 minutes and then product auto-exits to normal operation
• Power-Up Restore — if manual switch is forced off after a power outage, the lights will remain off
• LED Enable/Disable — flexibility for light sensitive requirements
• Lamp Burn-In Mode — seasons fluorescent lights
