Overview
The WattStopper LMPX-100 is a digital passive infrared (PIR) corner mount occupancy sensor designed for use with Wattstopper Digital Lighting Management (DLM) systems. This sensor detects occupancy in spaces up to 2,000 square feet using PIR technology and one of four interchangeable lenses, enabling energy-efficient automatic control of lighting and plug loads in commercial and institutional environments.
Featuring an integrated LCD display and programming pushbuttons behind a snap-down cover, the LMPX-100 allows precise adjustment of time delay, sensitivity, and walk-through mode directly at the sensor. A built-in infrared (IR) transceiver supports wireless configuration and remote control via the LMCT-100-2 wireless configuration tool. Out-of-the-box Plug n’ Go automatic configuration maximizes energy savings from the moment of installation.
Features
- Plug n’ Go automatic configuration for quick installation and maximum energy savings
- Detection Signature Processing eliminates false triggers and provides immunity to RFI and EMI
- Push n’ Learn functionality for system personalization without tools or a PC
- LCD display and pushbuttons for setting sensor and system parameters
- Infrared (IR) transceiver for wireless configuration and control
- Four interchangeable lens options for different coverage patterns and space types
- Compact 2.4 in. x 3 in. form factor mounts easily on wall or ceiling
- Sensor coverage tested to NEMA Guide Publication WD 7-2000
- Meets RoHS materials restrictions
- BAA/TAA-compliant models available
