Overview
Overview
Overview
The ENERLITES MDC-50L is a commercial-grade low voltage ceiling mount sensor that operates lights using a combination of passive infrared (PIR) and ultrasonic technologies. The dual-technology sensor features a 360° field of view fresnel lens that provides up to 1200 sq.ft. of PIR coverage and 1000 sq.ft. of ultrasonic coverage. This ceiling-mounted sensor operates lights ON/OFF based on occupancy and ambient light levels detected in the area. Ambient light level detection prevents the occupancy sensor from turning lights ON when the ambient light levels are sufficient. The sensor is compatible with the ENERLITES 91245 momentary switch for optional vacancy mode and manual ON/OFF operation. Note that a power pack supply (MPP-24) is required for the MDC-50L sensor to work.
Features & Benefits
- Dual-Technology Sensing: Combines PIR and ultrasonic technologies for superior accuracy and reliability in detecting occupancy
- 360° Coverage: Fresnel lens provides complete room coverage with up to 1200 sq.ft. PIR and 1000 sq.ft. ultrasonic detection
- Adjustable Time Delay: Easily set from 30 seconds to 30 minutes based on occupancy patterns
- Daylight Harvesting: Adjustable ambient light level sensor prevents lights from turning ON when sufficient natural light is present
- DIP Switch Simplification: Easy-to-use DIP switches simplify sensor adjustments for time delay and light level settings
- Adjustable PIR/US Sensitivity: Fine-tune both PIR and ultrasonic sensitivity settings for optimal performance
- Six Trigger Modes: Switch between PIR-only, ultrasonic-only, or combined sensing modes for maximum flexibility
- LED Indicator Lights: Flash when sensor detects motion via PIR or ultrasonic to verify active detection
- Zero-Crossing Technology: Ensures long relay life by switching at optimal points in the AC cycle
- Vacancy Mode Compatible: Works with ENERLITES 91245 momentary switch for optional manual-on/auto-off operation
- NEMA WD7-2000 Tested: Sensor coverage tested to industry standards for reliable performance
