The Wattstopper LMDC-100 is a dual technology ceiling mount occupancy sensor designed for commercial applications. It utilizes both passive infrared (PIR) and ultrasonic technologies for precise occupancy detection, contributing to energy-efficient lighting and plug load control. The device is part of the Wattstopper Digital Lighting Management (DLM) system and offers features like Plug n’ Go™ automatic configuration and Push n’ Learn™ customization. It is manufactured in China and is compliant with BAA and TAA standards for products produced in the U.S.
Device Specifications
The LMDC-100 possesses several key specifications relevant to installation and operation. The sensor’s color is white, and its construction utilizes ABS material with a matte finish. Its dimensions are 4.5 inches in width, 4.5 inches in depth, and 4.5 inches in height, with a volume of 44.55 cubic inches and a weight of 0.2 pounds. The ultrasonic frequency employed is 40 kHz.
The device is designed for ceiling installation and includes spring clips for mounting. It requires a load controller for full functionality and features adjustable time delay, indicator lights, and sensitivity adjustment capabilities. The LMDC-100 operates within a storage temperature range of 23° to 176° F (-5° to 80° C). It adheres to several standards, including UL, cUL, FCC part 15, RoHS, and PEP. The product’s UPC number is 754182926329. A product environmental profile is available.
Operational Technologies
The LMDC-100 employs a dual technology approach to occupancy detection, combining passive infrared (PIR) and ultrasonic sensors. The PIR component provides 360-degree coverage. Ultrasonic diffusion technology, utilizing the 40 kHz signal, extends the sensor’s coverage area. This combination, coupled with Detection Signature Processing, aims to minimize false triggers and provide immunity to radio frequency interference (RFI) and electromagnetic interference (EMI).
Installation and Configuration
The LMDC-100 is pre-set for Plug n’ Go™ operation, meaning initial adjustment is optional. However, full operational details and advanced features are available in the DLM System Installation Guide, which is provided with Wattstopper room controllers and accessible on the manufacturer’s website (www.legrand.us/wattstopper). Installation must comply with all applicable regulations, local and NEC codes. Wire connections must be rated appropriately for the wire size used.
The device supports Push n’ Learn™ functionality, allowing for customization without requiring tools or a personal computer. Digital Lighting Management components connect via a free-topology Category 5e DLM local network. An infrared (IR) transceiver enables wireless configuration and control.
System Integration
The LMDC-100 is designed to integrate with other components within the Wattstopper Digital Lighting Management (DLM) system. The documentation references a connection with an LVSW-102, though specific details regarding this integration are limited within the provided source material. The system utilizes a local network topology, allowing components to connect without a rigid, predefined structure.
Troubleshooting and Common Issues
The provided documentation includes questions and answers related to troubleshooting. One user reported a display showing an E06 error code with flashing red and blue lights, indicating a potential issue requiring further investigation. Another user inquired about configuring the sensor to function as a toggle switch, turning on with movement but remaining on indefinitely, which the documentation does not directly address.
A user also reported an issue where the LMDC-100, connected to an LVSW-102, failed to automatically turn lights on or off despite successful testing in 5-second mode. Another user requested information on adjusting the sensor timer using the four buttons available (configuration, feature, up, and down). A final question concerned obtaining the coverage pattern for the LMDC-100 within a Revit model.
Warranty Information
The LMDC-100 is covered by a 5-year warranty.
Compliance and Origin
The LMDC-100 is BAA and TAA compliant, indicating it is a product produced in the U.S. The country of origin is China. The device meets UL, cUL, FCC part 15, RoHS, and PEP standards.
Conclusion
The Wattstopper LMDC-100 is a dual-technology occupancy sensor intended for commercial lighting control applications. Its features, including Plug n’ Go™ configuration, Push n’ Learn™ customization, and integration with the DLM system, aim to provide energy savings and flexible control options. Proper installation, adherence to relevant codes, and understanding of the device’s operational technologies are crucial for optimal performance. The provided documentation offers a starting point for installation and troubleshooting, but users may need to consult the full DLM System Installation Guide for comprehensive information.
