• Measures actual light on the work surface and reduces the influence of stray light striking the photocell from nearby windows or incidental side lighting

DEFINITION Leviton’s photocell sensors precisely monitor either task or ambient light levels. As part of a Leviton lighting and energy solution, photocells work with other components in the system to automatically adjust light levels to a userdefined level. Photocells are most suitable for installation in rooms with windows and open spaces receiving substantial ambient light. Photocells must be hardwired to a compatible Leviton lighting control system. The photocell measures ambient light in a specific area and sends this data to a dimmer or relay that, in turn, adjusts fixtures to a constant lighting level as measured in that specific area. Daylight harvesting is achieved as lights in a room (with windows or significant, artificial ambient light) automatically brighten or dim depending on how much light the photocell detects.

BENEFITS • Constant lighting at the optimal level for greater visual comfort and acuity, which contributes to improved productivity • Provides convenient, automatic hands-free daylight harvesting when integrated with Leviton lighting control products • Lowers electric bills by reducing usage of lighting where ambient natural light is also present • Lumen maintenance opportunity compatible

DAYLIGHT HARVESTING With daylight harvesting, ambient (often natural) light supplements in-room, artificial light in order to keep a constant lighting level while simultaneously saving energy. This ensures unnecessary overhead lighting remains dimmed or OFF. This constant level is programmed into a compatible control device. Once hardwired to the photocell, the dimmer or relay receives the photocell’s real-time light measurement and maintains a steady level within the photocell’s area of detection

RULES OF OPERATION Measured light level = Light Maintain Level Action: Output to lights remains constant Measured light level < Light Maintain Level Action: Lights are brightened Measured light level > Light Maintain Level Action: Lights are dimmed

FEATURES • Indoor photocells designed with a flat Fresnel lens looks downward in a 60° cone of reference to measure actual light on the work surface and reduce the influence of stray light striking the photocell from nearby windows or incidental side lighting • Outdoor photocells are IP54 rated to guarantee ultimate protection from dirt, dust, oil and other non-corrosive material • Measures light from any source in the visible spectrum within a 60º cone or 180º angle of response depending on the model • ODC0P-00W photocell with 60° clear lens operates between 1-1,600FC. ODC0P should be surface mounted or direct to ceiling box • ODC0P-S0W switching photocell with 60° clear lens operates between 1-1,600FC. ODC0P should be surface mounted or direct to ceiling box • ODC0P-D0W dimming photocell with 60° clear lens operates between 1-1,600FC. ODC0P should be surface mounted or direct to ceiling box • PCCxD-00W, PCCxS-00W, PCCSD-00W line voltage photocells with 60° clear lens for applications where zone control switching, dimming, and demand response are required. Operates between 1-1,600FC. PCC photocells should be mounted to the ceiling in standard 4”x4” square or octagon electrical boxes • PCIND-000 indoor photocell with 60° clear Fresnel lens is default setting = 75-800FC sensing range; can be field adjusted to 800FC max sensing range. PCIND should be mounted to the ceiling, facing down • PCIND-0SV side view photocell for applications where ceiling mounting is required yet the view should be of the lighting entering the space through a window; or, for installation to the wall of skylights where the view should be up into the skylight. Default setting = 0-30FC sensing range; can be field configured with a jumper for a 3FC, 30FC, 300FC, or 600FC max sensing range • PCOUT-000 outdoor photocell is enclosed in a weatherproof housing with a visor for shading and lens protection. Default setting = 50-750FC sensing range • PCOUT-0SV side view photocell for applications where wall mounting is required yet the view should be of the lighting entering the space through a top/side and/or face of the photocell. Reference placement diagrams. Default setting = 0-30FC sensing range; can be field configured with a jumper for a 3FC, 30FC, 300FC, or 600FC max sensing range • PCATR-000 atrium photocell with opaque dome lens filters 33% of light level in upper atrium. Default setting = 215-2,690FC sensing range; can be field adjusted to 2,690FC max sensing range • PCSKY-000 skylight photocell with dark dome lens filters 90% of light level in skylight.
