The Lumen Maintenance Photocell (LMPC) is a sensor that’s attached to a wall that reads the amount of light in an area, and relays the information to a control unit that can make adjustments according to the user’s specifications. It can control as many as four dimmed or switched circuits per room with adjustable settings. The LMPC has an onboard digital readout that indicates foot-candle levels, voltage-out from 0V to 10V, and a baseline setting, which eliminates the need for a separate foot-candle meter. Users wall-mount the LMPC photocell in the desired room, and it’s setting and trip points can be adjusted locally or remotely.
