SANTA CLARA, CALIF.—WattStopper’s LMLS-400 and LMLS-500 digital photosensors were selected by Building Operating Management (BOM) readers as recipients of BOM’s 2012 Top Products Awards. The photosensors are part of WattStopper’s Digital Lighting Management (DLM) product line, and are specifically designed for easy integration with occupancy sensors and other lighting controls. DLM maximizes energy savings and return on investment (ROI), and meets or exceeds the latest code requirements.
Both products include a two-way infrared (IR) transceiver for communication with a wireless configuration tool, and the LMLS-400 features automatic commissioning for either switching or dimming. Either sensor can be configured for on/off switching, bi-level or tri-level step switching or step dimming, or continuous dimming for each controlled zone.
A menu-based handheld wireless tool is used for sensor configuration. The wireless tool also initiates the self-commissioning process for the LMLS-400, and prompts users to input light levels in order to quickly commission the LMLS-500. Once the LMLS-500 receives measured light levels for each control zone, it automatically recommends setpoints, simplifying the setup process compared to other open loop daylighting controls.
WattStopper’s LMLS-400 is a single-zone closed loop photosensor that can be installed on a ceiling or in a lighting fixture. The LMLS-500 is a multi-zone open loop photosensor designed to mount on a ceiling or in the light well of a skylight, and control up to three lighting zones. The digital photosensors simply plug into a DLM network and can easily be added, or exchanged for one another, if project requirements change. They are ideal for both retrofits and new construction.
The Building Operating Management Top Products Awards are 100 percent reader-selected and recognize the most popular manufacturers and suppliers of the year, as determined by building and facility executives who participated in a national survey. Award winners are featured in the January 2012 issue.
